Who is behind this project?



This news and research blog augments the World Hum Database and Mapping Project located http://www.thehum.info

Dr. Glen MacPherson lectured for 16 years at the University of British Columbia (UBC), training mathematics teachers in the Faculty of Education, and worked for 10 years with UBC Robson Campus with its GMAT and GRE curriculum program. He is also an ethnographic researcher, and high school teacher of physics, mathematics, psychology, general science, and biology. He lives and works on the west coast of British Columbia, Canada. His books, articles, and speaking engagements focus primarily on mathematics education.

After first noticing the Hum in spring of 2012 and discovering the Hum community, he sensed the need for a unified, moderated, and serious place for discussions and research surrounding the world Hum. This led to the World Hum Map and Database Project.

The leading theory is that the world Hum is an internally generated audiological phenomenon, possibly related to otoacoustic emissions.  (Note that tinnitus is also a self-reported audio effect, although it manifests quite differently from the Hum.) There are four competing theories.

This is a place for disciplined inquiry, and not for wild speculation and conspiracy. There are many entertaining and interesting websites available for those who want to indulge in those activities.

    There are moble devices that measure these things right down to 11 HZ. Why isn’t anybody using them?

    • Could you post a link to an example of one?

    • Peter Haartsen says:

      Last month on Dutch tv there was a short documentary on the hum. One interviewed civil servant had this handheld mobile device by bruel kjaer. He said that often no low frequency noise could be established when he visited people who had complained about the hum in their neighborhood. He had some device at home, and with that machine he almost always could help people finding the frequency that alarmed them all the time. He said that people most of the time can fixate the noise up to 1hz plus or minus. This convinced him that these people really do hear these specific frequencies, but that it seems not possible to establish the presence of the hum at their place with his handheld.

      The experience of relative quiet in the south of France earlier last summer, gave me reason for a second short stay in Siorac, a village near the river Dordogne. During these six days I experienced the hum mostly like I experience it at home in Middelburg, Holland.
      From the 14th till the 20th of September 2017 the weather in the region of this village was not really inviting to engage in (end-of-summer) outdoor activities. And yes, the hum was there all the time. Or maybe I should say: “I was there all the time”.
      My six day stay in Siorac in September made me think a bit more about the external or internal origin of the perceived hum, pressure or vibration.

      We all accept hearing the hum as a fact.
      If we can find out whether we are hearing the same hum, we will have ground for the next inference: ‘We hear this same specific hum, with these-and-these characteristics which we have been able to confirm independently at this time and location, by using a validated checklist’.
      At that moment we may have found a beginning of an answer to a problem that needs solving. Suppose that a company of three well-prepared persons travels to six locations worldwide to experience the hum as it has been reported to exist there. Their personal experiences with the hum should qualify them to represent the larger community.
      If the documented experiences of these three researchers show significant, if not very convincing similarity, it may bring us to a new inference:’experimental research informs us that at six locations worldwide three well-prepared fieldworkers have established individually to hear a hum with well defined characteristics. Their individual reports give rise to the belief that these three persons have been hearing exactly the same hum.’

      If we can come this far, we will have solved one part of the external vs internal origin of the hum problem. Or maybe we will have narrowed it down.
      We would have gathered convincing clues as to the fact that at least the hum seems to origin from a source outside the body, able to affect the experiences of three researchers in virtually the same way.
      If the hum would be produced independent from incitement from outside the body, it would be very hard to believe that three persons, together in one place, were having almost exactly the same experiences with a hum.

      The production of noise by the brain alone would be a very idiosyncratic, erratic process. Like it has been said on these pages before, no explanation can be excluded before all the missing information has been uncovered.

      Obviously any checklist would need to present qualifications of the hum-experience in a way acceptable to all informed hearers of the hum. Since experiencing the hum is a very individualised event, it may take some time to agree on acceptable general descriptions of various levels or patterns of the hum before a list shows enough quantitative and qualitative potential to be of serious use.

      Personally I think about moving to Siorac, or somewhere near this village. The days without the hum last summer were important enough to extend my stay in that region. If the hum after all turns out to be just as bad as it is in the Netherlands, then I have at least committed myself to this experiment. Nothing lost. And still there is some hope. With the hum I do not believe in coincidence, not after living with it for almost thirty years.
      These two weeks in Siorac were real. It felt good. If that kind of period of quiet repeats itself, whatever reasonable explanation I am lacking, I will have confirmed at least for myself that the hum can still be evaded to some degree.

      • Your suggested experiment would be an important one. It has been suggested many, many times before. In fact, I can probably dig up some 30-year-old references to it. We have already established the checklist you propose. If you search this blog you’ll find it. One obstacle for your experiment is money. There are other, more subtle problems as well. Regarding recordings, I’m not at all convinced that the Worldwide Hum has ever been recorded. Moir’s stuff is still all over the internet, yet every effort to chase down the precise details of his experiment end up with, “I’ll get back to you on that”. The also goes for his claim that the term “hum drum” comes from the Industrial Revolution (it does not, incidentally). If anybody claims that they can record a local acoustic hum, then there is some pretty basic beamforming software that can draw back vectors and triangulate the source. This is what Novak tried to do in Windsor, with mixed results. Within a few days, the Hum Map survey will be available in Dutch and German, and I encourage you and your fellow hearers to add to what we know.

      • George G. says:

        Peter, what you propose is a well thought experiment.
        If you do manage to conduct this exercise may I suggest you exclude hearers who are prone to the Hum constantly.
        From the number of readers who have offered to join Glen in D-Box experiments over the past few years I am confident that you will have no problems with finding suitable volunteers.
        Looking forward to reading your results.

    • taquahn says:

      I was just watching a video on the hum and i think i can hear it.It does not happen all the time but when it does it’s really annoying and get’s really loud.it sounds like a loud screeching sound sometimes i would ask the rest of my family if they could hear it but it seems like it’s only me

  2. Daniel Parks says:

    Hello Dr. MacPherson,

    I’m in the process of writing a novella entitled, “104th Meridian West,” about the strange disappearance of long haul trucks at longitude 104 W. as it passes through New Mexico. While this is a fictional tale, it contains a tremendous amount of truthful information. One of the noted characteristics of the area north of Tucumcari, New Mexico is an eerie low pitched hum in the desolate mountains north of New Mexico Highway 104. I would like to use your descriptions of the phenomena and mention your background as supporting information for the occurrence. My book contains no bad language or sexual innuendos… in other words it’s the kind of story I’d be happy for my grandson to read. I will be glad to send you the chapter that contains your name and background for your approval before publication.

    Thank you for your consideration,
    Daniel Parks

    • As much as it sounds like fun to have one’s name appear in fiction, I distance myself from any and all connections between the Worldwide Hum and fiction/fantasy. Refer to my name and research if it helps your plot, but understand that in no way do I endorse or support such conclusions. Also, note that evidence is piling up that points away from external sources such as military VLF transmissions.

  3. Frank says:

    Interesting that they are having the same issue defining the Cuba “noise” as we are with the Hum. http://nypost.com/2017/10/12/revealed-sound-of-the-sonic-attack-on-americans-in-cuba/ . Wouldn’t it be interesting if they were both related?

  4. Lisa Allen says:

    I think we should have a World Wide Hum conference somewhere. We’d probably have to have at least a few in different locations to get as many people to participate as possible, then put all of our findings together. We could conduct experiments and explore the surrounding area to see who hears the hum and have guest speakers and experts (you, Glen). Maybe we could learn something by bringing our collective experiences together in one place.

    • Simon says:

      Hi Lisa, I think this is great idea. I did post a proposal for a conference of this kind some time ago, but it did not generate any interest at the time. I personally think Vancouver would be a good location, mostly because it has a hum, (I have heard it!) and is a great city to visit for a few days away. I certainly would be very interested to meet a bunch of fellow hum hearers in one location, and hopefully take away something from the more learned amongst our community, who i am sure would need little persuasion to explain some of their ideas and research.

  5. Michael Curcio says:

    I recently moved to Florence SC. We are on the outskirts of the city. I became aware of a low level, low frequency oscillation a couple of weeks ago. It seems to be present wherever I go, in our home. My wife says she hears nothing.

    • Lisa Allen says:


      I am in Myrtle Beach and I hear it too. For me it started in February 2016. My husband, like your wife, also hears nothing. I’m sorry you are now a member of this “club” but are the same time I’m glad to know someone else hears it too that’s on this side of the state.


  6. Lisa Allen says:

    Did anyone else notice that the hum was unbearably loud last night after 2:00 a.m.? I actually thought it was some noise from a neighbor but it wasn’t – it was just the hum. It was frightening that this could be happening. Tonight seems like it could be the same as it’s getting louder and louder. I am in Myrtle Beach, SC – I don’t know if something is going on here that is making it worse.

    • Gail Hewitt says:

      I find it hard to believe the government at some level is unaware of this. Sometimes saying nothing speaks louder than words. People do report these kind of things to 911 etc. Why is there no drive by media attention to this phenomenon?

      • One could easily ask why there is no serious governmental focus on heart disease. If there were, why then would we need people to go door to door to beg for research funding? And that’s for a disease that is the biggest killer in society.

      • Janet Menage says:

        If the Hum is a side-effect of a military communications project, or similar activity, it may officially “Not Exist”.

      • Bill Wiemann says:

        Hallo Janet

        I also thought that many should also hear this “Huml” That was about 2 years ago. Now I know what this “Hum” is. It is generated in our central nervous System. The best Name for this is Tinnitus. Tinnitus can be a high pitched tone or a low pitched tone. None of whet (me also) hear is coming from outside. I mentiuoned here some weeks ago that if a Person takes a deep breath and makes a deep throat hum, his or her hum that is thought to b coming from outside somewhere will be gone for a short period of time. By me it is only 15 to 30 seconds of a very nice silence which sets in after the Person hums the deep tone. This works each and every time. I admit that I do not know why or how this humming will silence the hum that many here “have.”

        Give it a try: take a deep breath, hold your fist over your closed moulth and begin your deep hum which is coming from your throat. If you do this correctly, thi “Hum” will fade out for a short time. This silence that sets in is really something that many of us here are missing.

        One important Thing to know is that Tinnitus is not going to bother anybody when they are sleeping. That is because the Person is simply in a sleep mode and therefore Hearing is not all that important.

        Anyway, give it a try and let us know your outcome. Now, the next step in understanding this Hum is to find out why it happens to so many People in this World. What is known is that it is generated by the central nervous System.

        Bill (in Hof, Germany)

      • We’ve heard this prescription many times on this website, and for the record, nobody has reported to me that it does what the writer claims. But I suppose it does no harm to try, does it? Also, when you write, “What is known is that it is generated by the central nervous System.”, I’m curious: who knows that?

      • Gail Hewitt says:

        Tinitis is easily diagnosed by a compitent physician. Go see your doctor and if you are properly tested ignore this post.

    • annamaeforever says:

      It feels worse the last 2 weeks here in Orlando. Sound, vibrating and pounding up through the floor and through the bed.

      • Janet Menage says:

        Much worse here in West Wales, UK. I can hear it all day long, especially if sitting, and can only sleep using blue-tack earplugs & the radio on quietly by my pillow. Even so I’m woken at 5am, usually with a headache. The physical body vibration excludes tinnitus. Turning my back on the bedroom window also reduces the noise slightly.
        Question: Is the Hum worse at night because we are physically still rather than moving around? (remember the ‘head shake’ experiment). Is there some kind of ‘standing wave’ that requires a still object (house or skull) to bounce off?

  7. Lisa Allen says:

    To be honest, I’m not sure I can ever believe the hum is solely caused by internal factors. It seems to be very clearly eminating from a point beyond my body. It’s hard to believe something contrary to your own perception when you’ve been living with it day in and day out, for months or years.

    Even if the government, or whomever, knew about the hum, there are too few of us, relatively speaking, for them to care to do anything about it. What are we – about 2% of the population? I don’t wish the hum on anyone, but at the same time if a person in a position of power – a top military guy or a member of Congress or Parliament, started hearing it, that would probably move things along rather quickly! All we can do in the meantime is to keep pushing along doing what we we’re doing and to keep sharing our experiences with others.

  8. George G. says:


    At your suggestion, I have taken a look at the work of the late Dr. Gerber.

    Thank you.


    • annamaeforever says:

      Lisa, I so agree with every sentence you wrote. No, it is not internal, and if it was I would be happy to seek some kind of treatment. I do not know how anyone who is truly living with this thing could believe that it is internal. For so many valid reasons I am completely sure that it is external and NOT internal.

      • George G. says:


        I beg to differ. Over many years, and with the help of this forum, I have narrowed it down to my right ear. It is always there. If I face west I perceive it from the north. If I face east, I perceive it from the south,and so on.

        One of the ‘tricks’ I have learnt to help me understand it is to close my nostrils and mouth, and blow gently till my ears pop. By sustaining this pressure for several seconds the Hum is amplified tremendously. I use this method for finding Hum direction location. The source is always from my right, regardless which direction I face.

        I have tried to record it (accoustic and electromagnetic) with no results.

        I have buried geophones into the ground, I have set up large diameter coils, vertical and horizontal loop antennas, still no results.

        I have even stuck pipes in my ears and fed them into a sensitive microphone—still no joy.

        Until fresh and compelling evidence comes along, I have to conclude the Hum is within me.

      • Gail Hewitt says:

        If it is within you, it’s within a lot of other people too. How do you explain that? Maybe you hear something unrelated to this phenomenon. Something, shall we say, different?

      • Janet Menage says:

        George, I have been thinking about your experience with the valsalva manoeuvre (ear popping). For the tympanic membrane (eardrum) to function properly there has to be an equalisation of pressure on either side of it (think aeroplane travel). It may be that by popping your ears (which equalises pressure in the eustachian tube) your eardrum starts to work better. I find this interesting as one of my symptoms from the Hum is a feeling of pressure in my ears. Also of note is that one of the adverse health effects of infrasound is a feeling of pressure in the ears (as well as body vibration).
        Does anyone know whether seismic radar transmits as well as receives?

    • Janet Menage says:

      Just found some interesting quotes on the website allaboutheaven.org/observations/3806/221/the-hum-002277 :-
      “the Auckland Hum – On 15 November 2006, Dr. Tom Moir of the Massey University in Auckland, New Zealand made a recording of the Auckland Hum and has published it on the university’s website. The captured hum’s power spectral density peaked at a frequency of 56 hertz”.
      And:- “Conference on “The Hum” held at The Royal Society of Medicine, London, on the 25th of November 1989″.

      • Every last claim made by Moir went to a dead end when I chased down the details. He answered my questions with generalities, and waved his hands over the technical details of the supposed recordings. He claimed, for example, that the phrase “hum drum” came from the industrial Revolution. Nobody I know can find any evidence for this, nor for his other claims. Perhaps he can be motivated to publish full and specific details of the recordings (which he did not do, incidentally).

      • Janet Menage says:

        The Pembrokeshire Hum was 63Hz, Aukland Hum 56Hz, my bedroom Hum 50Hz, Dr Chris Barnes says 30-80Hz is the usual range if recorded. http://www.drchrisbarnes.co.uk/HUMCAVE.htm. His magneto-acoustic theory is interesting. My local Dan yr Ogof caves are limestone – if he is correct it should be silent down there. Interesting that he says Hum gets louder in copper mines. Anyone understand what he means by PC1?

  9. George G. says:


    Good question, I wish I knew the answer. I suffered an ear injury when I was young and reckless (silly diving stunt).

    Later in life I began to pay the price——–vertigo, sporadic pain from the right ear, and Hum. Continuous Hum.

    I cannot argue 100% that this is the cause, but to me it seems more probable than other theories——-for the moment!


    Thank you—–” the valsalva manoeuvre—” I wondered if there was a term for ear-popping.

    I have to agree with you. When I carry out the manoeuvre, not only is the Hum amplified, but external sound as well. The only difference is that the Hum comes from the right, where as other sounds arrive from their respective directions.

    Always learning——-.

  10. George G. says:

    Re: Dr. Barnes,

    I have looked at the link Janet recommended. Dr. Barnes’ theory/theories are indeed interesting, but rather general, and at times vague.

    Nothing in the presented work is new. You will recall in the early days of this forum Dr. McPherson pondered along similar lines, but as new data became available the direction of study changed accordingly.

    Although Dr. Barnes presents some original concepts, there are also some dubious sources suggested as references to back up his theory.
    I noticed a reference to The Resonance Foundation. Several references direct the reader to the HAARP project.

    Dr. Barnes’ credentials are impressive, but when I compare how far we, an informal group of interested Hum researchers have progressed, I am confident we are up there with the best of them. Lets keep going, nobody will solve this for us.


    You asked what PC1 meant;

    PC1 In the context it was written, probably refers to a classification of natural electromagnetic waves which impinge onto the earth’s magnet field.

    The author was probably suggesting that the Hum is modulated by these waves.

    P = Pulsations
    c = continous

    The number which follows denotes the frequency, or time of the pulsations. Therefore, Pc1 = Pulsations continuous 0.2 to 5 seconds
    Pc2 = ” ” 5 ” 10 ”
    Pc3 = ” ” 10 ” 45 ”
    Pc4 = ” ” 45 ” 150 “

  11. George G. says:


    Is it true that Alaska University now controls HAARP?

    If so, what about pulling some strings and get amongst it?

    This could be the lucky break we have been waiting for.

  12. George G. says:

    They will have access to excellent receivers used during the HAARP projects, both on-site and abroad.

    Maybe, during the course of their projects, if they encounter regular sinusoidal EM waves, in the frequency range of, say, 30 to 80 Hz, they may wish to
    give you a shout?

    • Janet Menage says:

      Are you saying that sinusoidal EM waves 30-80Hz are audible? Try MIT & DARPA as well. (MIT didn’t reply to my email).

    • Janet Menage says:

      I have written to the acting Head of DARPA, Dr Steven H Walker, as follows:-
      “Dear Dr Walker, I am a retired UK family doctor with 30 years medical experience in the NHS.
      For 2 years I have experienced an uncomfortable, low frequency droning noise, together with bodily vibration and pressure in the ears, worse at night and indoors, but constantly present and which disturbs sleep.
      As you will know, this is a worldwide phenomenon known as, ‘The Hum’, which has received much publicity and has been occasionally recorded as 30-80Hz but whose origins remain obscure.
      Please could you advise regarding DARPA’s knowledge of the phenomenon and information held as to its source?
      Thank you.”
      I will try MIT again. However, my guess is that this must be a secret programme, otherwise we’d know by know, given all the publicity.

  13. Lisa Allen says:

    I wonder if an online petition would help, with a statement on the top reading, “We, the undersigned, experience hearing what sounds like a low frequency noise throughout the day, at varying strengths, almost every day. For some of us this has been going on for several years. We have contacted our local electric company, city officials, neighborhood organizations, cell phone companies, etc., in an effort to locate the source of this noise to no avail. We have been to audiologists and neurologists, only to be told “everything looks normal.” We need help in determining the cause of what we call “the hum” as thousands of people around the world are effected and it poses health problems caused by lack of sleep, stress, ear pain and more. We are asking professionals and the organizations they represent to consider research into this phenomonon to help understand the cause of this constant droning noise that can hopefully lead to it’s elimination. This list of “hum hearers” is only a small fraction of those whose lives are impacted by this mysterious noise. There have been articles written about this and interviews conducted in areas where the hum was widespread (i.e., Bristol, UK; Taos, NM and others).”

    Then, when there are thousands of names on the petition, it can be printed out (for effect), put in an appropriately sized box, and sent along with inquiries such as the ones Glen and Janet and others have sent, trying to get some interest and answers. If Janet had thousands of names attached to the letter she mentioned above they would have tangible proof of the “worldwide” portion of the hum evidenced by pages and pages of names!

    • In general, I support all advocacy efforts in these areas. I would stress, however, in the strongest terms, to do what you have done here: keep the language subdued, medically based, and free from conjectures and language that immediately raise flags or turn off the typical reader. It takes 10 serious letters and articles to undo the damage by one irrational person. What you have written above looks quite good – I would suggest a few minor changes, but that’s all. Somewhere on my hard drive I have a generic letter to the editor that I will share here if I can find it. Best of luck with your efforts.

      • Lisa Allen says:

        Glen – Ok, thank you. I agree with what you said and can make changes to what I wrote above if you let me know what you suggest. Also, do you have any thoughts on where the best place would be to put such a petition? I am not a super techy person but I can probably figure it out or get someone to help me.

  14. George G. says:


    A couple of points of clarification;

    a) There is no suggestion in my post that radio waves are audible—They are NOT!

    b) Your letter to DARPA claims the Hum has occasionally been recorded. False! The Hum has NOT been recorded.

    Please review your letter.

    • I missed that when I scanned the letter. I must agree insofar as I’ve seen no good evidence that the Hum has ever been recorded. The fact that there is a such a wide discrepancy in perceived frequencies within a specific locality raises serious questions about whatever might be captured on audio recordings. Moir’s claims lead to dead ends. Novak’s work in Windsor is irrelevant to our global study. If I had my choice, I would prefer that this reference be removed from the text of a letter.

      • Janet Menage says:

        We cannot know for definite that it has never been recorded. Indeed 50Hz at 20dB was recorded in my bedroom! ( with no clue of where it came from). DARPA & MIT will either disclose what they know or they won’t.
        Incidentally, there have been two cases recently of coastal communities in the UK experiencing a mysterious smell with no clue as to where it has come from (the first smelled like chlorine, the second like burning plastic). If the Hum is an auditory hallucination caused by EMF, maybe olfactory hallucinations could be produced also? I only say, “IF”, George!!

      • No doubt that many localized disturbances have been recorded. But after we have eliminated all reasonable possible sources of such noises, we are left with the generic global issue that we are studying here. Also, I think the word “hallucination” is very unfortunate here because of its connection to mental illness – schizophrenia in particular. I’ve never seen the words “hallucination” and “tinnitus” used together in the same sentence. Whether there is such a thing as induced smell (causes by EMF or otherwise) is a very interesting question, but I have no evidence surrounding that, nor am I aware of any.

  15. Gail Hewitt says:

    How about contacting your state senator or congressman to form a committee to investigate this situation.

  16. Lisa Allen says:

    I don’t think I would get anywhere if I just sent a letter, but I think if there was the visual effect of seeing the names of thousands of people who are also affected by this, I’d have a better shot of getting someone’s attention. I could print a portion of the data base here and send it along with a letter, but that would be alot of detailed reading. People are busy and move quickly from one thing to another, so I want to do something to capture someone’s attention simply and immediately. That’s why I thought if I could include a petition the person receiving the letter would see it’s not just one person, it’s many, many people who are affected by this and maybe that would increase our chances of obtaining some real interest. I found a website that helps you to create a petition, but I don’t know if enough people would sign it; that’s why I thought of extracting information from this website if I’m allowed to do that.

    • I think an “open letter” style might work, undersigned by certain people. Although all people are equal in my view, it might help to at least emphasize folks with academic and medical credentials, if only to help get the attention of laypeople and to have them take a serious look at the phenomenon. I’d want to help with the editing. This exercise might take some compromise and joint effort.

  17. Lisa Allen says:

    I agree. I can start a rough draft and you can edit and make changes, and add the names of those with the pertinent credentials. Then I can make a list of people to send it to and personalize each letter (instead of “To Whom it May Concern”). Getting the names and addresses of the right people to send it too will actually be more work than writing the letter and some suggestions would be welcome! I can easily get the names and addressed of members of Congress, but professionals in the appropriate science fields at universities, governmental agencies, private businesses, etc., I will need help with. I can post the letter here after I write it and we can go from there – editing, lists, etc.

  18. George G. says:


    I look forward to reading DARPA’s reply.



  19. Lisa Allen says:

    Glen – I started writing the letter but I need to know what specifically we are asking help with. Maybe you can add that in? I will keep working on it over the next few days and I can either post it here or email it to you and anyone you want can add, delete, edit, etc. It is so loud tonight that it got me into a writing mood.

  20. Alyssa Taylor says:

    Dr. Glen MacPherson,
    I’m a 22 year old that currently resides in Kingston NY. I moved here in August from Connecticut, and just recently over the last month I have begun hearing this Hum. I am losing sleep over it because it’s all I hear at all hours. I am exhausted and I feel like I’m going insane because I only hear it in my apartment, and my fiancé is sick of hearing me complain about this noise because he can’t hear it. The only time it ever seems to stop is when I have tv or music playing. Is there any other way to cancel out this noise? I have tried ear plugs and having tv or music on all night. If you or anyone have any recommendations it would be greatly appreciated.
    A fellow Hum hearer

    • There is no shortage of quack cures and snake oil, but from what I can see, background masking noise is the only thing that seems to work right now.

    • Janet Menage says:

      Hi Alyssa
      You may not have seen my previous posts. I have found that ‘blue tack’ earplugs wrapped in clingfilm cut down the Hum by about 50%. That, together with a transistor radio next to my pillow, on low volume with the bass turned up, helps to mask the noise. It doesn’t help the vibrational aspect but it does facilitate sleep most of the time.

      Glen – I note with interest that one sufferer hears more of a screeching sound. My neighbour experiences vibration in his solar plexus which is more unbearable than the audible Hum noise. Interestingly, when he shakes his body it disappears momentarily (similar to the ‘head shake’ experiment previously mentioned on the forum). I’m wondering whether the external source of the Hum is actually a stimulus which triggers different effects in different hearers?

      Are there any Hum hearers on this forum who are also electrosensitive? (EHS). I would be interested to know if there is a correlation, as Hum hearers and EHS sufferers both comprise around 2-2.5% of any population, it is said. Wi-fi makes my head & ears buzz and gives me a headache & brainfog. Mobile phones make my ear heat up, so I only use them to text.

      Also, I’ve found that low atmospheric, wet weather reduces the intensity of the Hum/vibration, but high atmospheric pressure increases it to unbearable levels sometimes. I was in Manchester at the weekend and had to get out of bed in the house & go and sleep in my campervan, which reduced it somewhat.
      http://www.drchrisbarnes.co.uk found a remarkable correlation between Hum severity & the weather, apparently.

      • Dr. David Deming, one of the early big names in Hum research, noted that there were a few times when he heard a second sound – a highly irritating, grating, higher pitched mechanical noise. I have never heard this, although it is reported occasionally. Weather changes might cause changes in Hum perception due to changes in air pressure, for example, but I’ve seen no correlations that are consistent across the database. Dr. Barne’s stuff is a fascinating read, but of course, some of his speculation can now be rejected (he didn’t have access to the data we now have).

      • Janet Menage says:

        Glen – as a matter of interest, how did you seal the lid on the Deming box when you got in it? The reason I ask is that I did some experiments with aluminium foil to determine whether EMF could be blocked and whether that would have any effect on my perception of the Hum.
        When I wrapped my mobile phone in foil, it could not receive a signal. When I coated a cardboard box with foil, the phone could still receive a signal inside when the box was shut. I did a similar thing with the cast iron/enamel bath! I glued aluminium foil over the whole top surface area, thinking it might become a place of refuge from the Hum. Sadly, the phone still received a signal when within, so I didn’t bother trying it in person.
        It seems that the seal to block EMF has to be absolute. Does your mobile phone work inside the closed Deming box? Apologies if you’ve already covered that on the forum.

      • The lid is cut from very heavy gauge mild steel, and so its own weight made the seal (recall that I used a radio-tight gasket to make the seal from steel to steel).

      • But I agree that this should be verified electronically, I am grappling with a technical issue surrounding the EM detector. Stay tuned.

      • Janet Menage says:

        Glen – did your mobile phone work inside the Deming box?
        I found a New Scientist article, dated December 1979, describing the Hum phenomenon https://books.google.co.uk/books?id=66VHTgzbIEUC&lpg=PP1&pg=PA868#v=onepage&q&f=false. Obviously well before the public had mobile phones.
        However, Michael A Persinger of Laurentian University in Canada stated that the electromagnetic soup in the environment, particularly ELF EMF, overlaps the human nervous system. Former DARPA scientist, Dr Paul Batcho, warned that, “cell towers were transmitting RF bands within the range of human brain activity and that …..the technology goes back to the V2K (P300) mind wave synthetic telepathy technology of the 1970s”.
        If HAARP also helps to create a plasma in the earth’s atmosphere to facilitate communication technology, it should be no surprise that some individuals’ body chemicals and brain electrical systems react abnormally.
        As I’ve said before, holding a radio aerial or walking near a radio, often improves its reception. The Hum I hear & feel reminds me of the old valved radio sets that hummed. I imagine that if I laid on top of a (very!) large old radio set (!) while it was switched on, I would get a similar experience to what I feel now – humming and vibrating.
        I’ve not even had an acknowledgement of my emails to DARPA & MIT.

    Hi Alyssa,

    I’m so sorry you are hearing this hum noise too. I just bought a new white noise machine from Amazon that I like because it can be turned quite loud. It’s called Dreamegg and has several different sounds – a fan, rain, the ocean, lullaby, etc. You can set it to play all night. I use that in conjunction with a clock that also has sounds. I like an ocean sound and fan together, personally. There is also a great website called mynoise.net, and you can adjust the frequencies of the different sounds to your liking: here is a link to the one I find most soothing that also, most importantly, helps to block the sound of the hum: https://mynoise.net/NoiseMachines/rainyRiverbankSoundscapeGenerator.php?c=0&l=7369567636231720222400.

    Also, someone here mentioned that if you put your hand between your ear and the pillow that helps to block the hum; I do that now too and it works for me.

    I hope this helps.


    • Alyssa Taylor says:

      Thank you Lisa! I’ll definitely have to look into purchasing one of those.

      • annamaeforever says:

        It is not the sound, I have been able to desensitize that somewhat better. it is the vibrations on my floor and bed that are the worst. I am trying to figure out how to survive the vibrations/pulsing/shaking. Sometimes the bed and floors shake and it is so loud under my house and there are knocking sounds and shakes on my bed it can really be terrifying. I believe that it is the military somehow. I am a therapist and I am trying to treat myself through this hell.

  22. Lisa Allen says:

    Hi Glen – I just wanted to ask if you received the draft of the letter I sent you. I was just afraid it might have gone into your spam folder. Thanks.


  23. Lisa Allen says:


    That sounds awful. Are you on the first or second floor? Is it every night or just sometimes? I’ve had periods where my bed vibrated and seemed to shake and it was frightening to say the least. One thing I’ve noticed is that on nights when the hum is particularly loud or active, and then the a/c or heat comes on, the combination of the two seems to be greater than the sum of its parts and that’s when my bed is more likely to vibrate. I don’t know if that is always the case but it may be something to play around with if you can. I put anti-vibration pads under the feet of my bed but that didn’t seem to help much, but there are different kinds so maybe that’s worth experimenting with. It’s awful that we have to live like this – I wish we could figure out what on earth is causing this and put an end to it!


    • annamaeforever says:

      Lisa, There seems to be some schedule of activity but it is always on. AC no difference. I wondered about the anti vibration products but a friend in the UK said that he tried it and it didn’t work either. I’m in Orlando and have been in this home for 39 years didn’t start until 2016. So, from 1979 to 2016 it was peaceful. Its not going to drive me away I love my little home and who knows, it may be there too, or come there wherever “there is that I go .. I am going to try cognitive restructuring and treat myself. I am going to convince myself that it is the military protecting us somehow. Thank you for responding Lisa your support helped me.

      • Lisa Allen says:

        Annamae, I live in Myrtle Beach, SC and also started hearing the hum in 2016. I was here for 8 years prior to that, living in peace and quiet. I wonder if there is something that started on the East Coast in 2016 that affected both Florida and South Carolina. I wonder about the submarines since we are so close to the ocean. I also love my house and don’t want to move and like you, don’t know if I would hear it elsewhere anyway. If I move it won’t be just to get away from the hum, there will have to be another reason too. I don’t know what cognitive restructuring is, but I hope it works! I’ve thought about going to a hypnotherapist to see if that could be of any help. If I come across anything that might help with the vibration I will let you know. Lisa

  24. Real Techs says:

    I visited a tone generator website on my PC. I wanted to try to match the hum to a tone so I could answer that question. When the lower frequency tones became difficult to hear I turned up the volume on my cheap computer speakers. I was hitting play and stop to investigate the tones and to my horror the stop button seemed to no longer work (would not stop the sound). Two things became apparent. With the volume all the way up the hum is nearly perfectly replicated from the speakers which have “nothing” being played. When tones around 10 Hertz are played along with the hum that comes from the idle speakers they seem to blend together. My speakers are emitting the hum always but they have to be turned way up for it to be heard. What type of interference would cheap computer speakers broadcast? The sound of the Earth? The magma in the core moving at a different speed than the mantle or other layers surrounding it? The sound of the universe? The sound left over from the big bang similar to the “snow” on a TV between stations which should have no other (known) signal?

    Would you like to know? Perhaps I can share this with you.

    • annamaeforever says:

      Lisa I thought it was interesting that the whole time they were searching for the 44 men in the sub/Argentina it was so quiet here. Almos a week. Cognitive restructuring is a process used with clients and patients where the therapist does hypnosis for calming and then offers suggestions for a different perspective which will serve the client or patient in a more positive way. I have a friend in Ms. who was there for 24 years before it started. She is having a very bad time with it and I feel for her so much. I think I have seen posts from people on the West coast too.

    • annamaeforever says:

      Tech, When we had the hurricane all of our power was off for 6 days, for many miles. The sounds of the generators replicated the sound that I hear so closely that I thought it was the same sound. I made an error on this site when I said that the sound was still there in the absence of the power outage. It wasn’t, it was the generators all around me that I heard. So, the thing/hum stopped when there was no power. Most of Fl. went dark, it was awful but peaceful with no vibrations for the 6 days. I think I am confused reading your post but it does sound interesting. ps. we have under ground power and transformers close to the sidewalk curbs

  25. Lisa Allen says:

    Annamae, hmmm, that is interesting about the submarine in Argentina and that there was no hum where you are during that time. For a few days I didn’t hear anything, but it was after Thanksgiving, and I attributed it to an ear infection. There are people on this site from the West coast that hear the hum; according to the world hum map on this site it seems to be all over. Thanks for explaining what cognitive restructuring is. If/when I look for a hypnotherapist (there are none in Myrtle Beach, unfortunately) I will mention that! I will have to tell them about the hum. I hope they don’t brush it off as tinnitus; that would be annoying. I feel bad for your friend in Mississippi, too. I feel bad for all of us. But at least we have each other to complain to. And Glen and others are trying to figure out what it is, so that gives me some hope that maybe one day we’ll know what’s causing it and maybe be able to stop it.

    • Gail Hewitt says:

      Maybe what you need to do is invite others into your house and see how many of them hear what you hear. That way people would have some objective statistics to measure this situation by. Keep a record. If everybody who heard it did that then there would be less confusion and perhaps even some kind of consensus.

  26. Gail Hewitt says:

    Then perhaps people should be instructed to find evidence to support their observation instead of waiting for people to write in that they are “hearing things” that are in their minds. This position is just adding to the confusion that already exists. Scientists want independant observation by unrelated observers who don’t have, shall we say, a dog in the fight. No conflict of interest or unseen objective to support. Instead of a petition, perhaps a record from observers who have substantiated the observations of the people who have been plaugued by this phenomenon would be noticed by a government official like a congressman or senator or in the case of Canada an MP or some such representative of the government. I can’t believe the government is totally ignorant of all of this. There’s too much of it to just ignore it and write it off as “psychic phenomenon”. To substantiate something you have to report on it. Why not go to the press and see if you can entreat them to come and examine it? The press seems to have more influence on shaping opinion than scientists do.

    • There’s been widespread press coverage over the past four years, much of it serious. In my view, there is value in all types of reports – scientifically worded and otherwise. With some exceptions, the people who have a dog in the fight are the people who can hear the Hum. If a person suffers from tinnitus, I can’t see how that disqualifies their objectivity in advocating for tinnitus research, just as a cancer survivor is not disqualified from soliciting funds for cancer research. I think the stories of Hum hearers are valid, crucial, and add to what we know.

    • annamaeforever says:

      Gail, There have been countless people in my home when the thing is railing, no-one has ever heard/felt it. My daughter lives down the street, she hears it very low but doesn’t feel it. My neighbor got on my bed one time and she said she felt “a shaking” but did not feel the floor shaking. so, if “people” come to investigate there will probably be nothing to hear or feel! That is why I feel so hopeless because I AM THE ONLY ONE WHO FEELS THE STRONG VIBRATIONS THAT SHAKE MY BED AND MY FLOOR AND MY ENTIRE HOME AND IT SOUNDS LIKE THERE IS A JET PLANE UNDER MY HOUSE.

      • Italics are usually preferred to all caps.

      • Janet Menage says:

        Annamae, you are not alone in your experience. After 2 years of being driven mad by the hum/vibration, my son gave me these noise-cancelling earphones and they work! The hum/vibration is reduced by 90-100%. Might be worth giving them a try? Good luck!

      • Lisa Allen says:

        Janet, what is the brand name of the earphones? Are you able to sleep with them? Thanks.


      • I edited out the direct link to Amazon (I often do this, for several reasons), but Janet: feel free to post back with the make and model. Glen.

      • Janet Menage says:

        The box says model TT-EPO1 from http://www.taotronics.com. Yes I can sleep in them. Comfortable lying on my back; lying on my side the earpiece digs in a bit so just making a cloth doughnut to rest my ear on! Sometimes just having one earphone in is enough.

      • Janet Menage says:

        I see Glen has edited out the amazon link, which is a shame, as the specific earphones are difficult to find on the taotronics website. I would advise against bluetooth – go for the wired ones – they are called Active Noise-Cancelling Headphones in Ear Earphones (Wired Earphones, Noise Cancellation, 15 Hours Playtime, Aluminium Alloy Construction,Gold-Plated Jack, Remote Control, Additional Ear-buds and Hooks).
        Perhaps Glen could let you have my email address then I can send you the link?

      • There are reasons why I would prefer no direct links to Amazon, but I’m sure with the information you’ve provided, a person can very quickly track it down. Thanks.

      • Lisa Allen says:

        Janet, Thanks for that information. I’m going to see if I can find them on Amazon. On another note, I just got back from the ENT (Ear, Nose and Throat) doctor. I had had an ear infection but I also talked to her about the hum and brought her a copy of a page from the database showing descriptions of the hum. I pointed out to her that there were over 16,000 entries and she was taken aback by that. She asked if ear plugs helped and when I told her “no,” she said that makes her think it’s coming from inside of me! She said ear plugs should block ALL sound, not just high frequency as I suggested to her. Later on when it gets loud I will put in my ear plugs and see what happens. I’m not 100% sure she’s right, but I’m not a doctor either. She said there is a test called MRA where they look at the arteries about your neck, and they can see if there is any kind of blockage that could be causing a person to hear the sounds of their own body. I may do that at some point. But despite all this I would swear on my own life that this noise is external.

      • Outstanding. This is precisely the sort of thing that makes a difference. When physicians and specialists are presented with clear, calm, and rational information, our cause moves forward, even if only a little. Conversely, every ridiculous conspiracy is a setback. I suggest using the logic of tinnitus, which is: if we believe people who self-report high-frequency sounds, why would we not believe people who self-report low-frequency sounds?

      • Janet Menage says:

        I think it depends on what type of material the earplugs are made of. High density seems to work better for low frequency noise. The ordinary foam ones don’t block the hum, in my experience. If the hum can be blocked by putting the fingers in the ears (bone is high density) then it isn’t tinnitus (in the medical sense) as blocking external sound would make tinnitus worse due to reducing the masking effect of external noise.

    • Lisa Allen says:

      Gail, It is not clear from your post – do you hear the hum?

  27. simon says:

    Amen to that Glen. Whether internal or external, it is clear to me that the hum is sensed via the tissues of all our ENT systems, not just the ears (or just the right ear in a lot of cases) and I have found recently that I can silence the hum for long periods (long enough to fall asleep anyway) simply by a combination of head shaking (thanks Bernie!) and repeated swallowing. I have no idea how this is possible, but amazingly it seems to work. Anyone else had this experience? Personally I still believe the stimulus for the hum to be external, as the other sure-fire way to silence the hum here in the UK is simply to cup my right hand over my right ear. This too works remarkably well, but it is not so easy to do when lying in bed of course..

    • Janet Menage says:

      Simon, I have found that lying still tends to make the hum worse, eg lying in bed or sitting still in the living room during the day. As you say, moving the head on the pillow reduces it for a while. Swallowing changes the pressure in the eustachian canal so that will also move the eardrum to some extent. I have felt for some time that there may be an issue of some kind of ‘standing wave’ developing, whether acoustic or EMF – ie it bounces off the walls of the house or off the sides of the skull. Outdoors, where there are fewer surfaces and we move around, reduces the hum effect. And, yes, we feel the hum via lots of our senses, eg there are deaf musicians.
      Someone on the forum suggested lying with a hand between ear and pillow and that worked for me.

  28. Real Techs says:

    I would like to know if there are ‘listeners’ who are comfortable or comforted and not tormented or even annoyed by the hum. I was sorry to read so many people seem distressed and I would like to suggest some alternative thinking to help those who feel physical or mental discomfort that they believe is caused by the hum. I think if you understood your gift (not handicap) you would discover that it is a very special and beautiful thing to be able to detect this hum. I don’t mind when it wakes me and I try to listen for it on days when it feels diminished or obscured because I don’t want it to mysteriously go away.

    • You’re not the first person to suggest this. There have been a few posters over the years who view the Hum as some sort of “companion”. I don’t take that view, and the majority of hearers, from what I can infer, view it as a considerable nuisance at best. My suggestion is to do a search through the database (as opposed to the map), and you can find a wide variety of commentary.

      • Real Techs says:

        Thanks Dr. MacPherson. You have what seems like a qualified and lengthy scientific interest in the hum and I’m more than thrilled to have found some of your work here. Forgive me if you’ve previously stated this as I’ve yet to read everything here; Have you stated, or are you interested in sharing, your personal feelings on the hum? Not what the theories are, or any science, how it makes you feel and if that has evolved since 2012. If you find the question not relevant or private I understand. Also, do you follow any other online discussions or well moderated forums like yours related to our hum?

      • I have done so many times during many interviews. Some major ones include: The New Republic, the Walrus, Al Jareeza (video documentary), Coast to Coast AM, and The Conversation (the only article written in my own words). Cheers, Glen.

      • Lisa Allen says:

        Real Techs, I’m glad you are not bothered by the hum the way most people are, including myself. That makes me wonder if it sounds different to different people. I just can’t imagine anyone liking what I’m hearing – lol! Do you hear that droning sound that has an electronic quality and reverberates in your ear? How would you describe what you hear?


      • annamaeforever says:

        Since so many people feel it why is it called hearers and not feelers? Over and over I read that people feel it. I hear it and feel it. To me, it is a sound that is felt.

  29. Lisa Allen says:

    I tried my foam earplugs last night and the hum was louder; it almost seemed to be coming from inside of me. A few minutes ago I tried Mack’s silicone putty earplugs and that was better but I still heard it. When I stuck my fingers in my ears I don’t hear a thing! I wonder why that is?

    Janet, I ordered those noise cancelling earphones you mentioned. I hope they work but if they don’t I’ll return them and try a different kind.

    If the US military was the cause of the hum would people be hearing it in areas of the world where they don’t have a presence? I wouldn’t think so, unless the sound can travel vast distances.

    • Janet Menage says:

      Hi Lisa, fingers crossed the earphones work! I think high density materials absorb the hum better – fingers are flesh, bone and liquid which combination seems to absorb well. Also, fingers are ‘alive’ and have an energy field of their own which could interfere with whatever energy the hum might be (if it is a type of energy).
      Re the military. I heard the hum in a cove surrounded by cliffs where my phone had no signal. I would think the military have the globe pretty much covered with satellites….think google earth.

      • Lisa Allen says:

        Hi Janet, thank you, I hope they work too! I am going to look up high density ear plugs and buy some if they exist. You’re probably right about the military; if that’s the cause of the hum there’s not much hope for us unless more and more (and more powerful) people start hearing it. Maybe there are many sources of the hum – military amongst them. I hope we find out in our lifetimes.

  30. Real Techs says:

    Lisa, et. al., Here is my brief history: When I first heard the hum at the very end of 2006 I had just moved into a new home and when I was asked how I liked my new house after my first night I said, “I love it but one of my neighbors must have been working on their muscle car inside their garage and I could hear it and almost feel it when going to sleep.” That was the end of the discussion for many years except for occasionally asking my wife, “do you hear that?” The hum has become way more pronounced within the past year and even more in the last few weeks. For the first time it has awakened me in the middle of the night seeming very loud to the point I want to wake my wife and say, “that, do you hear that?” Fortunately for her I don’t, because I’ve realized she does not hear it, at all. During the day I occasionally walked around the house trying to find the source and even told my wife recently, “the next time I hear it I’m going to turn off the main breaker to see if shutting down all electronics makes it stop.” I never got around to that test but in early November this year I traveled to another house which is two hours away and very different in many ways from my home. To my astonishment I could hear the exact same hum at the other house. My wife doesn’t seem as fascinated, she seems more concerned for my sanity as many wives (or husbands) might be. I had no idea that any one else could hear the sound until I decided to type something about “hum” into my search engine less than two weeks ago. My observations (and initial reactions) are so similar to the rest of you that I was thrilled to have arrived at them independently. They are so close someone could easily wonder if I had adopted them from others by suggestion (mass delusion).
    I recently thought of the sound as being similar to the sound of a light saber from the movie Star Wars being waved about, not in a battle scene (where they smash together with a loud crash) but rather training or warmup light saber sounds. No, I’m not going off the deep end of science fiction here. It just occurred to me today that that sound can be something used to describe the whirling, wobbling electromagnetic radio signals being interpreted by our brains as approaching single digit Hertz hums. I’ve also described it to non-listeners as a somewhat distant airplane (sometimes prop and sometimes jet) that never gets closer or farther away. I don’t think I have super hearing because it feels like a gland or cavity in my brain is able to sense the signal as an otherwise imperceptible vibration. I believe there are other mammals with “acoustic” receptors such as these. I’m not suggesting I have that, just describing the feeling.

    • Lisa Allen says:

      Hi Real Techs, thanks for sharing your experience! It’s interesting to hear how other people first come to hear the hum, their reactions and how they deal with it. We’re all different and have different stories and that’s interesting. Also how we describe it. A lot of people say it sounds like a “diesel engine” but I never do because I don’t hear diesel engines enough to know for sure what that sounds like. I guess we use things we’re familiar with to describe how it sounds, and we’re familiar with different things so we use different terms. I’ve heard someone else describe it as a distant plane that never gets closer or further away – I think that was Glen but I’m not sure. Well, I hope it continues to not bother you too much. When the volume is low I can live with it but sometimes it gets very, very loud and that is more difficult. I think our spouses suffer too because we suffer, but I’m sure they must get tired of hearing about it all the time, too.

      • annamaeforever says:

        Lisa, Janet, Tech, are you all still there I can’t find any new posts. I was thinking, if it is the military and if only some of us can hear/feel this thing isn’t it possible that some of our enemies can hear/feel it too? If it is communication with subs/low frequency radio waves or elf and they are aware of it then what good is it for our security? Its so unbelievable to me that my family standing right next to me cannot hear/feel the banging underneath my house.

      • Janet Menage says:

        It might just be a side-effect of some technology rather than an end in itself. It’s interesting that I’ve had no acknowledgement of two emails to M.I.T. and one to DARPA. Why ignore me? If they don’t know what the hum is, why not say so? On the other hand, if they do know what it is (and it would be strange if they didn’t know), they might not want to say.
        Can you not communicate with MIT via UBC, Glen?

  31. Lisa Allen says:

    Annamae, I hope you can see these posts. Are you also reading the open forum posts which are listed to the left of the home page? It’s weird to me too that no one I know hears this but me. This has wreaked havoc on my ability to get a normal night’s sleep. But I’m happy my husband and siblings believe me and take an interest in it (to some extent). And I’m glad we have each other on this forum too. We know what it’s like and it helps to know that others out there can hear it, too. Imagine if you were the only person in the world who heard it? That would probably have driven me crazy already!

    Janet, I do think the hum is a side effect of some technology and not an end in itself, as you stated above. Maybe the people at MIT and DARPA are just very busy and have timetables and deadlines to meet and that’s why you haven’t heard from them. Maybe we ALL need to send letters to M.I.T and DARPA to get their attention! If you post their addresses and the letter you sent maybe some of us can send variations on that letter, and maybe they will answer one of us eventually!! I thought the “open letter” that Glen suggested was a good idea, with many signatures, but maybe everyone is too buy now with the Christmas holidays just around the corner. I still think it’s a good idea, though.

    • Janet Menage says:

      Hi Lisa, I think MIT & DARPA have enough staff to answer a simple email. I contacted them via their respective websites.
      A communication from university to university might carry more weight and be harder to ignore.

  32. Real Techs says:

    Space is said to have no sound because there is no air to carry the waves but the radio emissions from space can be interpreted into sound. NASA has some great recordings from our solar systems available online at NASA.gov if you search a bit there. Consider just the sounds of our solar system and then add as many galaxies as your imagination will allow. Now consider our very protective atmosphere and magnetic field. This atmosphere is thought to capture and maintain a resonance of most Earth sounds natural and/or man-made. You can read about The Schumann resonances (SR) and think about how that fits with working theories #2 and #3 as stated here. As our atmosphere evolves both naturally and artificially it can change our relationship with things from space. As added greenhouse gasses can trap more inside our atmosphere so can a hole in its ozone layer (for example) let things in. For me the hum is the Universe. https://www.jpl.nasa.gov/spaceimages/details.php?id=PIA16881 Our carbon has existed in space before and not for a short period of time. You were once a particle traveling through space. You have only been enjoying the relative quiet of this planet for a short period of time. We are the ones from out there and it is beautiful. You can learn to love the sound as you would the lulling, comforting sound made by a terrestrial vehicle taking you home for the holidays. Let the hum remind you of the enormity of it all and the importance of enjoying your time here. Don’t sweat the small stuff. The hum can only bring you awareness and consciousness, it cannot harm you. -More to follow if it helps anyone and our host will allow.

    • I quote directly from the article:

      “For this sound file, the patterns in the sky observed by Planck have been translated to audible frequencies. This sound mapping represents a 50-octave compression in going from the actual wavelengths of the primordial sound waves (around 450,000 light-years, or around 47 octaves below the lowest note on the piano) to wavelengths we can hear.”

      Interesting stuff for sure, but this has nothing to with what we are studying here. Thank you for your post, but this will be the last one regarding this particular NASA news story.

      • Real Techs says:

        My oversight, I must have forgotten that I found that piece through your work here otherwise I wouldn’t have mentioned it again as though I found it independently.

        Are you exclusively studying sounds believed to be of terrestrial origin? Also, have you ever been asked to listen to a recording from one of your readers and are you willing to indulge in such folly?

      • I have received and listened to many recordings; some of them are hoaxes, some of them recorded with cell phones (which have extremely poor low-frequency response), and some of them cannot be replicated. To my knowledge, the Hum has never been recorded in a high-quality and replicable way. The fact that different people in the same area will report different dominant frequencies leads me to think that the Hum is not a sound in the classic sense. Standard sounds are reported by listeners as being at a similar pitch, usually very similar.

  33. Susan McIntyre says:


    This is what I believe the Hum might be, and I believe it is a simple, rational explanation that can account for all the symptoms. For example, the Taos Hum (continuing even after people move away), the article here https://newrepublic.com/article/132128/maddening-sound describes the woman hearing a humming sound, her bed vibrating, dizziness/vertigo, nausea, etc. with her husband having tinnitus, and even people writing about paranoid conspiracy theories transmitting sounds, voices, and images directly into the brain, “creating numerous pains and sensations throughout the body and significantly altering energy level and emotional states.”

    I experienced all these things during an urban outbreak of an airborne infectious disease that doctors mistakenly believe is “rare” in immunocompetent people, but is not. Based on my symptoms during an urban outbreak, I believe this infection can cause Fibromyalgia and Dysautonomia (which occurs after a virus-like infection, and this would this explain why it’s comorbid with IBS). This pathogen is known to cause tinnitus (my ears have been buzzing for 3 years). It made my bed vibrate and the headboard bang against the wall (Fibromyalgia symptom). It gave me various aches and pains that felt like pin pricks, pinches, and burning. It gave me vertigo/benign paroxysmal positional vertigo. it can cause nausea, and is known to cause wild mood swings (pseudobulbar effect), anxiety, OCD, depression, paranoia, auditory/visual hallucinations, delusions, fatigue, etc. It gave me MS symptoms (including visual). It also gave me insomnia, presumably from the pathogen acidifying the blood and releasing adrenaline

    I’d like to share information I learned during my workplace’s outbreak of an airborne infectious disease that can cause malignancies, precancerous conditions, rheumatic diseases, connective tissue diseases, autoimmune symptoms, inflammation in any organ/tissue, seizures, migraines, hallucinations, etc.

    My coworkers and I, all immunocompetent, got Disseminated Histoplasmosis in Dallas-Fort Worth from roosting bats, the most numerous non-human mammal in the U.S., that shed the fungus in their feces. The doctors said we couldn’t possibly have it, since we all had intact immune systems. The doctors were wrong.

    More than 100 outbreaks have occurred in the U.S. since 1938, and those are just the ones that were figured out, since people go to different doctors. One outbreak was over 100,000 victims in Indianapolis. 80-90+% of people in some areas have been infected. It can lay dormant for up to 40 years in the lungs and/or adrenals.

    This pathogen parasitizes the reticuloendothelial system/invades macrophages, infects and affects the lymphatic system and all tissues/organs, causes inflammation and granulomas, etc. It causes idiopathic (unknown cause) diseases and conditions, including hematological malignancies, autoimmune symptoms, myelitis, myositis, vasculitis. etc. It causes hypervascularization, calcifications, sclerosis, fibrosis, necrosis, eosinophilia, leukopenia, anemia, neutrophilia, pancytopenia, thrombocytopenia, hypoglycemia, cysts, abscesses, polyps, stenosis, and perforations, GI problems, hepatitis, focal neurologic deficits, etc. Many diseases it might cause are comorbid with other diseases it might cause, for example depression/anxiety/MS linked to Crohn’s disease.

    It at least “mimics” autoimmune diseases, cancer, mental illness, migraines, seizures, etc. It’s known to cause rheumatological conditions. It causes hematological malignancies, and some doctors claim their leukemia patients go into remission when given antifungal. My friend in another state who died from lupus lived across the street from a bat colony. An acquaintance with alopecia universalis and whose mother had degenerative brain disorder has bat houses on their property.

    Apparently, even the CDC didn’t know bats CARRY it and shed it in their feces, although they knew it could grow in bird and bat feces. Researchers claim the subacute type is more common than believed. It is known to at least mimic autoimmune diseases and cancer, and known to give false-positives in PET scans. But no one diagnosed with an autoimmune disease or cancer is screened for it. In fact, at least one NIH paper states explicitly that all patients diagnosed with sarcoidosis be tested for it, but most, if not all, are not. Other doctors are claiming sarcoidosis IS disseminated histoplasmosis.

    The fungus is an Oxygenale and therefore consumes collagen. It’s known to cause connective tissue diseases. Fungal hyphae carry an electrical charge and align under a current. It causes RNA/DNA damage. It’s known to cause delusions, wild mood swings, and hallucinations. It’s most potent in female lactating bats, because the fungus likes sugar (lactose) and nitrogen (amino acids, protein). What about female lactating humans…postpartum psychosis? The bats give birth late spring/summer, and I noticed suicide rates spike in late spring/early summer. A map of mental distress and some diseases appear to almost perfectly overlay a map of Histoplasmosis. Johns Hopkins linked autism to an immune response in the womb. Alzheimer’s was linked to hypoglycemia, which can be caused by chronic CNS histoplasmosis. The bats eat moths, which are attracted to blue and white city lights.

    I believe the “side effects” of Haldol (leukopenia and MS symptoms) might not always be side effects but just more symptoms of Disseminated Histoplasmosis, since it causes leukopenia and MS symptoms. What about the unknown reason why beta receptor blockers cause tardive dyskinesia? The tinnitus, photophobia, psychosis “caused” by Cipro? The hypersexuality and leukemia “caused” by Abilify? Humira linked to lymphoma, leukemia and melanoma in children? etc.

    From my experience, I learned that NO doctor, at least in DFW, will suspect subacute and/or progressive disseminated histoplasmosis in immunocompetent people. Some doctors, at least the ones I went to, will even REFUSE to test for it, even when told someone and their coworkers have all the symptoms and spend a lot of time in a building with bats in the ceiling. Victims will be accused of hypochondriasis. In fact, the first doctor to diagnose me was a pulmonologist, and the only reason he examined me was to try to prove that I didn’t have it, when I really did. No doctor I went to realized bats carry the fungus. And NO doctor, at least none in DFW, even infectious disease “experts,” understand the DISSEMINATED form, just the pulmonary form, and the only test that will be done by many doctors before they diagnose people as NOT having it is an X-ray, even though at least 40-70% of victims will have NO sign of it on a lung X-ray. It OFTEN gives false-negatives in lab tests (some people are correctly diagnosed only during an autopsy after obtaining negative test results) and cultures may not show growth until after 12 weeks of incubation (but some labs report results after 2 weeks).

    One disease of unknown cause that could be caused by Disseminated Histoplasmosis: I suspect, based on my and my coworker’s symptoms (during our “rare” infectious disease outbreak) and my research, that interstitial cystitis and its comorbid conditions can be caused by disseminated histoplasmosis, which causes inflammation throughout the body, causes “autoimmune” symptoms, and is not as rare as believed. I read that “interstitial cystitis (IC) is a chronic inflammatory condition of the submucosal and muscular layers of the bladder, and the cause is currently unknown. Some people with IC have been diagnosed with other conditions such as irritable bowel syndrome (IBS), fibromyalgia, chronic fatigue syndrome, allergies, and Sjogren’s syndrome, which raises the possibility that interstitial cystitis may be caused by mechanisms that cause these other conditions. In addition, men with IC are frequently diagnosed as having chronic nonbacterial prostatitis, and there is an extensive overlap of symptoms and treatment between the two conditions, leading researchers to posit that the conditions may share the same etiology and pathology.” Sounds like Disseminated Histoplasmosis, doesn’t it?

    My coworkers and I had GI problems, liver problems, weird rashes (erythema nodosum, erythema multiforme, etc.), plantar fasciitis, etc., and I had swollen lymph nodes, hives, lesions, abdominal aura, and started getting migraines and plantar fasciitis in the building, and haven’t had them since I left. It gave me temporary fecal incontinence, seizures, dark blood from my intestines, nystagmus, benign paroxysmal positional vertigo, various aches and pains (some felt like pin pricks and pinches), tingling, tremors, and chronic spontaneous “orgasms”/convulsions. Suddenly I was allergic to pears (latex fruit allergy?). I had insomnia (presumably from the fungus acidifying the blood, releasing adrenaline) and parasomnias. I suddenly had symptoms of several inflammatory/autoimmune diseases, including Fibromyalgia, Sarcoidosis, ALS, MS, Sjogren’s syndrome, etc. that have disappeared since leaving the area and taking nothing but Itraconazole antifungal.

    No one, including doctors, could figure out what was wrong with us, and I was being killed by my doctor, who mistakenly refused to believe I had it and gave me progressively higher and higher doses of Prednisone (at least 2 years after I already had Disseminated Histoplasmosis) after a positive ANA titer, until I miraculously remembered that a visiting man once told my elementary school class that bats CARRY histoplasmosis….so much of it that they evolved to deal with the photophobia and tinnitus it causes by hunting at night by echolocation. There’s a lot more. I wrote a book about my experience with Disseminated Histoplasmosis called “Batsh#t Crazy,” because bats shed the fungus in their feces and it causes delusions and hallucinations, I suspect by the sclerotia it can form emitting hallucinogens (like psilocybin and dimethyltryptamine) along with inflammation in the CNS. (Schizophrenics have 2X of a chemical associated with yeast, part of the fungal life cycle.)

    Thank you for your time,

    Susan McIntyre

    P.S. I would inspect homes/workplaces/areas of people experiencing the Hum for bats, which can travel up to 6 miles away in any direction from their roost to feed. Although, the people could have picked up the fungus in their past or during traveling/staying somewhere besides their homes/workplaces.

    • A (very lengthy) treatise on the subject which, I note, contains no references at all except for the article in which I appear. Setting that aside, it offers no explanatory value when considered against the Hum Map, which correlates strongly with population density, and not with bat populations or with prevalence of the condition you describe.

      • Real Techs says:

        Yea, but that’s a great name for that book. I wonder if one of the doctors propposed that. What is the suggestion here, that nearly every disease is caused by bat droppings? That those who hear the hum are batsh#t crazy? While the amount of research and presumably accurate scientific/medical terminology is impressive I’d bet part of the problem is that the delivery gives doctors and scientists auto-narcolepsy. I would suggest that doing something to kill or drive away the bats is not a good idea since they eat the deadliest animal on the planet, the mosquito. I’ll take spontaneous orgasms and the hum over Malaria any day. Either way, in the interest of getting to the bottom of this hum I will investigate the possible presence of bats in a six-mile radius in every direction of everywhere I have lived or visited or passed through over the past forty years that I may have been carrying dormant bat-scat.

      • I don’t think I agree with the full content of what you wrote, but it’s a legitimate opinion.

    • Peter Haartsen says:

      Hello Susan,

      I have been reading your thoughts about what is (in your opinion) the cause of this worldwide hum that many people are hearing/feeling.
      You present us with an impressive accumulation of variables which may be causing people to hear a hum/feel a vibration. Thanks for sharing these thoughts. I understand you really have to deal with challenging phenomena in your personal life. Suffering never gets easy. So I thank you for your effort to empathise, and your trying to share with us a rational approach toward this hum.

      The first two sentences of the first alinea of your posted text reveal quite a lot of what follows in your report.
      You have this belief about what the hum is, and about it’s explanation (sentence one). Based on your understanding of parts of an article on the Taos Hum, you base this (your) belief on reported symptoms by a woman hearing the hum, quoted in this article (sentence two).

      In the second alinea you present us with a plethora of phenomena which affected your personal life so badly that it hurts to even think of it happening to anyone.

      I think I understand how your personal experiences are a force in themselves to make you express every bit of sense you can make out of what you have been going through. And I think many many people can empathise with you.
      But on these pages it is not any type of pathology that drives this quest for hard-data answers to questions concerning the worldwide hum.
      So all in all I hope that you can give room to the prevalent assumptions which dominate these pages concerning the hum.
      Any rationalisation concerning the hum may bring us forward in formulating the proper questions about it’s origin. If your contribution helps this big search forward, thank you.

  34. Real Techs says:

    Glen, I was wondering if you saw this article and either way if you would care to comment on it. https://www.smithsonianmag.com/smart-news/mysterious-world-hum-recorded-seafloor-first-time-180967487/ I was a bit disappointed that there was no mention of the 2% of people who hear or feel something (possibly) similar. I would also like to know if you think they should produce their recording so that 2% of the population could determine if they can hear/feel it when it’s played. It would be nice if the recording could be altered in such a way as to make it audible to all people without fundamentally changing how it would sound because I would like to decide if their hum is similar to the hum I hear. If they really captured our hum, we should be able to detect it (unaltered) when played.

    • This is the same research that we’ve been discussing for the past few days, and it has nothing to do with what we are studying. Alas, the vast majority of the public – and indeed several readers of this blog – think that the Worldwide Hum has been solved. And that is not so. Good news is that I will be on Irish national radio on Thursday where I can set the record straight.

  35. Shane says:

    Hum “hear-er” not a hum sufferer here. Dr. Glen, when I read your experience w/the hum it sounded pretty much exactly like my experience. Even a cough or shuffle of the feet make it go away but as soon as it’s silent, the hum returns. I think I noticed it for the 1st-ish time about 3-4 years ago. It is a fragile thing that is unnoticeable to me with even a slight noise of any kind present. To me it is a curiosity more than anything. I can only hear (feel?) it indoors and the house has to be darn close to dead silent. I can hear it while outdoors but but very very faintly. Even the slightest breeze makes it go away. Outdoors “hearing” for me is very rare as conditions have to be just right. We live in a rural setting. We also have some high tension lines running north east to south west and vice versa but they are about a mile away. I’ve read your research but not all of it. Too much to do/busy. I’ll keep tabs on this. This is the 1st information I’ve found that isn’t some sort of conspiracy theory or other crazy things. I have asked my wife once or twice if she hears it and the answer is no. After she asked me if I was going nuts I quit asking her about it. 🙂 No biggy. I don’t lose sleep or have any other issues because of it either.

    • Janet Menage says:

      It will be interesting to see whether unperturbed hum-hearers continue to have the same experience or whether it changes over time, ie whether some kind of sensitisation takes place.
      I started hearing/feeling the hum 2 years ago and it gradually became more intrusive until sleep was disturbed and I experienced an uncomfortable pressure in my ears even during the daytime when sitting still. Thankfully, noise-cancelling earphones have brought a great deal of relief. I wonder if any other hum-hearers have noticed a change in their experience over the years?

      • George G. says:

        Hi Janet,

        Now that you mention it, my Hum has increased in pitch slightly over the years. My early impressions seemed to indicate a fundamental of 30 to 50 Hz.

        Today, I would describe it as 50 to 70 Hz. Always a sine wave. Before your post, I did not consider if a shift has occurred globally, I assumed it was simply part of my ageing process.

        If there has been a subtle change in pitch, I would also be very interested in other hearers reports.

        Why did you ask if others have noticed change, your thoughts please.

      • Janet Menage says:

        Hi George, I asked about subjective changes in hum intensity for a couple of reasons. Firstly, I was fascinated to hear that some people on the forum find the hum a positive experience and miss it when it’s not there. This surprised me, as my hum has always been a real nuisance. I wondered whether some people’s positive experience may change over time.
        Secondly, since I still suspect EMF to be involved in a type of sensitisation process (obviously unproven), I was interested to know whether people’s hums got worse over time, thus adding some weight to the EMF sensitisation hypothesis.
        I still don’t know why my noise-cancelling earphones work (but very thankful that they do!) – it could either be because the hum is a real, airborne sound which is blocked by the aluminium construction, or whether it is EMF (also blocked by the aluminium).
        Obviously it’s not a good idea to fear the hum, as the anxiety itself may be damaging to the body. But, equally, we have no idea whether or not the hum is harmful to biological processes. If it’s EMF it may be (www.bioinitiative.org). Since we don’t know, avoiding judgement either way is probably helpful.

  36. Real Techs says:

    Shane, Glad you aren’t suffering. I’m not either, I just have an increased awareness of the hum lately. If you don’t mind, I have a couple questions based on you being a hear-er. How long ago (before you found this site) did you start looking online for information about a (the) hum? Besides noticing it and being curious about it, have you ever found yourself listening for it, like you’d almost miss it or be disappointed if you couldn’t hear it? Since you first noticed it 3-4 years ago, have you noticed any changes in it recently? If you care to answer, thanks, if not no worries.

    • Shane says:

      If I had to guess, the 1st time I tried finding info about it online was maybe a year or so ago. Honestly, I haven’t tried very hard to learn about it.

      My work/business is seasonal. Winter gives me a little time on my hands to research curiosity things when they pop to the front of my mind.

      The 1st thing that actually made any sense was a thing called “mains hum” which is electrical power. As stated in my initial comment we do have what I call “high tension” lines about a mile away. I’ve been out hunting/hiking and have stood under such lines in other places just trying to see if I could hear anything. I hear the electricity “sizzle” at the insulators some but nothing like the “hum”.

      If electricity is the cause, I’ve come to the conclusion that being close to it doesn’t work. Like most (very) low frequency sounds I’ve heard in my life–they’re harder to hear the closer I am to them (to a point). It’s hard to explain.

      To satisfy my curiosity, I’d love to have a major power outage so I KNOW the main lines are dead just so I could see if the sound is still present. On another note, at my business I can hear it to if it’s quiet enough. I know we’re surrounded by electrical lines so the only definitive way (to me) to verify or debunk my little theory would be a rather major power outage.

      I’ve never been disappointed if I can’t hear it. The thought just randomly pops into my head to try and hear it from time to time. Usually there is too much ambient noise around me to hear it. Winters where I’m at are kind of harsh but it is the best time to hear it. We heat w/wood and I’ve a fan or two running constantly so I never hear it unless I shut everything down. Shutdown usually only happens as spring is breaking or unusually warm days.

      I’ve never noticed any changes in the hum. To me, it is a very steady, nonfluctuating sound.

  37. George. G says:

    Shane, Real Techs,

    So refreshing to read your comments.

    Initially, the Hum caused me great anxiety. I would often blame it for restless sleep. A few times it infiltrated lucid dreams, but all in all, it has never harmed me in any way.

    Now days it’s a good mate of mine.

    We have been together for 40 years. I have grown to accept it as part of me. And like you fellas, I only hear it when my mind is empty of stimulation, whether that be sound, sight or thought.

    That last statement is the key here.—–If I empty my mind of all stimulus, the Hum fills it. So be it.

    Real Techs, you must be an Aussie (“no worries”). You reckon it’s changed in any manor recently? How so?

    Cheers for now, and I sincerely hope we can inspire others to appreciate this thing called Hum, rather than fearing it.

    • annamaeforever says:

      Shane, power was out for many miles here in Orlando during hurricane. Everything was dead and dark for a week. but, everyone had large generators and they were everywhere loud and sounded just like the hum thing so I couldn’t figure out WHAT I was hearing. I do not remember the vibratory shaking though so I think it was absent during that time. After the power went back on it took quite a few days before I felt the vibrations and heard the thing. During the power outage I remember being in bed and thinking well at least the bed isn’t shaking…

  38. George G. says:


    The Hum can certainly be a nuisance, but over time I experienced the opposite to what you expect, i.e. as I got used to “hearing” it I began to ignore it.

    I also learnt this valuable treatment; Do not dwell on it. The more you ignore it, the less intrusive it is. And the more you think about it, the more annoying it becomes.

    With regard to an external origin, my perceived shift in Hum pitch over the years has not been confirmed throughout this forum. This suggests the origin is internal. If it was external, many others would be reporting a change in pitch.

    I am in complete agreement with you that we should not fear the Hum. As a doctor you obviously have seen how harmful anxiety can be, and I sincerely hope those who live in fear of it take notice of what you wrote, it is excellent advice.

    • Simon says:

      George, I think you are on to something here. I struggled with the hum for years, but since becoming more accepting of it, it seems less of an intrusion into my life. Of course, I would rather it stopped, but I think that changing one’s attitude to it is the key to successfully managing it. I kind of tried to distance myself from the forums and discussions around the the hum too, but curiosity draws me back in from time to time, as naturally I would like to see a resolution to the problem eventually.

      • George G. says:


        That’s great news, I’m glad you are managing to live with it. Let’s hope other sufferers take notice of this easy and effective method.


  39. Lisa Allen says:

    Last night my husband heard the hum, too. To verify that we were hearing the same thing, I asked him to tap on my arm what he was hearing and I tapped on him what I was hearing, and we were tapping the same pulse. And he heard it this morning too. It was very loud (to me, but not to him) which is probably why he was able to hear it. This verifies to me that there IS an external sound, although I don’t dispute that something internal may be causing us to hear it more clearly.

    I also hear it in the home of a woman I visit nearby, but it is slightly different and not as loud. I’ve heard it in many places and in each place it sounds slightly different, yet I recognize that it is the same hum. If it was only internal, I would think it would sound the same no matter where I went, but that isn’t the case. I wonder too if it is louder in a brick house than houses of other construction material because it is loudest in my house which is brick.

    • Peter Haartsen says:

      Lisa, it looks like you have found the answer to one of the important questions about the origin of the hum. I feel happy because of this fact. It’s a good message to begin a new year with. Happy New Year.

      • Lisa Allen says:

        Peter, yes, I feel the same way. It was an exciting moment when I knew for sure that we were hearing the same thing, validating the hum as an actual, external noise. Thank you and Happy New Year to you, too.

  40. George G. says:

    Hi Lisa,

    Has your husband heard the Hum before, or is this the first time?

    My wife and I have heard it simultaneously, but not often, usually one hears it and one does not, so I’m not sure about the external source view.

    Either way, we are fortunate that both of us are aware of its existence.

    • Lisa Allen says:


      This is the first time I was 100% sure that he was hearing what I was hearing in the exact same moment. A few other times he’s said things like, “I hear something” but when I asked what it sounded like, I assumed it was something else because the description didn’t match what I was hearing. It’s possible it was the hum and it doesn’t sound the same to everyone, or it could have been another noise. But the other night was different. We were hearing the identical noise, and after living with this all alone until now it was a pretty awesome discovery to know that he was able to hear it too, when loud enough.

      • George G. says:


        What you described is exactly how it happened to us. Two people in the house, one a long-term hearer the other a “novice.”

        I’m going to make a prediction. I envisage over a period of time your perception of the Hum will periodically fall out of sync with your husband’s perception.

        One of you will say the Hum was very loud last night, whereas the other will say they didn’t hear it at all.

        The fact that you are now both aware of the Hum will enhance your research capacity. This is a good thing.

        Looking forward to more reports.

      • annamaeforever says:

        Lisa, Could he feel it also? My daughter lives around the block and she hears it but doesn’t feel it and doesn’t hear it as loud but we have both agreed that it sounds like high end generators since we matched the sound during the hurricane. My friend and neighbor got on our bed one day when it was railing and she said “I feel something, like a shaking” but didn’t hear or feel it at her house, I did hear and feel it at her house. She lives 2 doors away.

  41. Lisa Allen says:

    George, it’ll be interesting to see if he starts to hear it more now, but I doubt that will happen unless it’s really loud like it was the other night. But we’ll see.

    Annamae, I just asked my husband your question and he said, “It was such a low frequency that I could feel it vibrate in my body.” To me I feel the vibration more in my ears I think, though it’s hard to describe exactly. Maybe the sound has to reach a certain threshold before it can be felt and it’s just not loud enough for your daughter to feel it. That’s also interesting about your friend feeling it in your bed, but not in her own home so close to yours. That your daughter and friend can hear or feel it too is more proof that there is an external component to this.

  42. Lisa Allen says:

    There was no hum today (Christmas)! Did anyone else experience that?

  43. Lisa Allen says:

    George, Oh, I didn’t know that (or I forgot). Thanks.

    • George G. says:

      At the time, it was proposed that during Xmas some form of industry or agency had taken time off for the festive season.

      When I read your post yesterday, it did not occur to me whether I could hear the Hum during Xmas, simply because i am not bothered by it.
      I then noted its absence, at 2115 UT. It returned at 2210 UT, ramping up from low to high in aprox. 8 minutes.

      I also noted the day was your Xmas: my Xmas was the previous day. (Dec 25 your time is Dec 26 here)

      This made me wonder if the Xmas day lull originates in the northern hemisphere. You may recall several posts discuss the possibility that although the Hum may be internally generated, an external stimulus may exist. The authors of those posts are well qualified people, and their suggestion is logical.

      Before we ponder any more, it may be a good exercise to mark this in our 2018 calendars, and take precise notes next Xmas, in real time (UT).

      If we can get enough people interested in the exercise, this may also help the forum in adopting a true time coordinated reporting regime.

      What do you think?

  44. Lisa Allen says:

    George, I think that is a great idea. I looked up Universal Time and found this World Clock Converter:


    For me, since I’m in EST, UT is five hours ahead. It was dead quiet until very late at night, and then I heard only the faintest pulsing – not enough to cause any problems sleeping. Today is about the same, relatively quiet compared to what I normally hear. So this is what I will record on my calendar:

    From 12/25/17,13:00 UT to 12/26/17, 6:00 UT – NO HUM (that is 8:00 a.m. on the 25th to 1:00 a.m. on the 26th EST)

    From 12/26/17, 6:00 UT to the present time, 12/27/17,13:30 UT – Intermittent, barely audible hum (that is 1:00 a.m. on the 26th to 8:30 p.m. on the 26th EST)

    Does the military slow down operations on Christmas? I wonder what businesses do? Anyway, I will put this info on my calendar for December 2018 and hopefully others will note their experiences as well if they’ve noticed a difference on Christmas day as I did.

      it seems that it is worse for us on holidays. so far the worst I have ever experienced it was on the last presidential Election Day night. but this Christmas was not as bad as last Christmas.

    That’s interesting, Annamae. Obviously it’s not the same for everyone.

    Happy New Year everyone, maybe this will be the year of discovery and the end of it..

    Happy New Year, Annamae and every other hum hearer. Let’s hope and pray for that!

    I am an engineer and as a company we were surprised to receive complaints from about 1km away from a high capacity gas burning stack even though alongside the unit the noise levels were clear but acceptable, even to health inspectors and environmentalists. It was described as a low frequency noise. Similarly large capacity generators could be ‘detected’ as running even though the exhaust noise at the plant was nothing to worry about

    When an engineering company based in Dorset tested for development a similar high capacity incinerator (with powered fans) complaints from residents around the town were eventually plotted and found to centre on the incinerator at a distance of 1.5 km and at times of testing. Although difficult to understand, it seems that the noise forms an umbrella and comes back to ground at a distance, probably distance dependent on the intensity of source.

    Putting this into perspective, in each of the 3 examples only a small proportion of people could hear the noise and only a few found it to be a problem.

    It seems to be a similar story to large windmills….some people say they can hear them but despite walking around many of different size, my wife and I certainly can’t.

    I’m sorry to say that the noise is likely to be a product of ‘modern’ society and the services that we all demand and therefore those affected willl have to live with it or move

      Very interesting and informative post Derek, but possibly a bit glib with your final statement. Sure we all want and need utilities of various kinds in the modern world, but does this mean that industry should have free rein to produce harmful noise and other forms of pollution that harm peoples’ well-being and the environment? Just saying..

      Derek, Move where? I’ve lived here for 39 years and never experienced anything like this until June 2016. So, if we move, it could “come there” too. A bit of sensitivity and compassion would be appreciated.

    This seems to tick a lot of boxes such as historic, percentage of hearers, and even public holidays.

    I particularly like the umbrella effect, where sound from a source may bounce of a ceiling medium and end up somewhere else. As the medium density varied, reflective and directive qualities would too.

    This would very easily fit in with the externally stimulated/internally generated Hum explanation.

    A very good post.

    I have recently learned about ballistic gelatin and wondered if anyone has used it to try and block out the hum. This is a description:
    “Ballistic gelatin closely simulates the density and viscosity of human and animal muscle tissue, and is used as a standardized medium for testing the terminal performance of firearms ammunition.”
