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 now works 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.

    Derek, I hope you never hear what we hear, but if you did, you would understand why it bothers so many of us. Loud, constant, low frequency noise can be very irritating, especially when it gets much louder at night just when you’re trying to go to sleep.

  2. Lisa Allen says:

    In case anyone is interested, I wanted to say that I ordered and received the ballistic gel from a medical company online that sells it for the purpose of training medical personnel (since it is similar to human tissue). I bought it because my finger is the only thing that can block out the hum when it’s loud, so I wanted to see if something made from a material that was similar in density and viscosity would also block it. Well, when i press it against my ear I cannot hear anything. I have tried it several times. When I hear/feel that pulsing hum when I put my head on the pillow, and then press the small sample of the gel against my ear, it is silent. This is the only thing that has blocked the hum for me. I am afraid to put it in my ear, however. But if these can somehow be made into earplugs they would block the hum. I can melt them down, shape them into small ear plugs, and then insert them into a foam earplug that the middle has been cut out of. I don’t know if that will work but I’ll try it when I have time. This is what it looks like (still in plastic wrap):



    • I’m glad it worked for you.

    • annamaeforever says:

      Hi Lisa, Please tell me where to get it and what to order. Thanks

    • william Hoffman says:

      ear plugs only help slightly but my fingers block the noise just as you have mentioned. I only have to put a finger in one ear and the noise is nearly gone. It can be either ear but it only takes one. I find this fact interesting, there has to be an explanation for this that can offer clues

      • Lisa Allen says:

        I agree. I bought a stethoscope for $12.00 online a while ago and found that that also blocks the hum; that too would be worth finding out “why.”

  3. Lisa Allen says:

    Annamae, I bought it from Hominics Medical. I bought a bag of gel samples (photos in prior post) and also a bag of the #1 gel cubes. I recommend buying the bag of samples. It’s only $10.00 and you can experiment with them and see which works the best for you. Gel #1 is the most dense and most like human tissue. Gel #5 is the softest but it still works ok. I haven’t tried #2, 3, or 4 yet (maybe tonight). Last night I was trying to sleep and heard that pulsing noise and put the #5 sample between my ear and the pillow (inside the plastic bag it came in) and it blocked the hum enough for me to fall asleep. Gel #1 works better but isn’t as comfortable because it’s harder. Anyway, I hope it works for you. Let me know how you like it.

    • It’s probably a good time for me to mention that in no way do I endorse this product or any claims associated with it. This product is being suggested by a blog member. Glen.

      • George G. says:

        If you allowed my Aeroplane Jelly crack to get through the filter, you would not have had to worry about endorsement rules.

        They would have loved the publicity, and who knows, they may even have offered some funding.

        (I am an eternal optimist)

        Ha ha and cheers.

  4. Lisa Allen says:

    Correction: Gel #0 is the most dense (not #1).

  5. Lisa Allen says:

    George, you piqued my curiousity and I had to look up Aeroplane Jelly – I never heard of it before. Well now I know something new, thank you! It’s a jello type dessert in Australia I guess. Maybe one day before I die I will actually have an oppornity to talk about Aeroplace Jelly with someone. 😉

  6. George G. says:


    I owe you an explanation.

    Yes, it is a jelly desert which dates back to the time when aircraft were becoming popular, especially with youngsters, so the manufacturer decided to marry the love of aircraft with their product. They even had a theme song for it.

    Aeroplane Jelly is fruit flavoured gel crystals. You simply add hot water and let it sit in your refrigerator till it sets.

    When I read your comment on ballistic gel, my initial thought was something toxic entering your ear canal.

    After researching ingredients of ballistic gel, and what it cost, I figured you could make your own much cheaper. So, I commented that perhaps you should use Aeroplane Jelly instead of ballistic gel, that way if it did not achieve the desired affect of blocking the Hum, at least you could enjoy eating the rest.

    Moderators, in their wisdom, decided to block the post.

    I had a few beers, (as Australians do) and I was being silly.

    Hope we are still friends,


  7. Lisa Allen says:


    I don’t know if you’ve seen this, but below is an article about your segment on Inside Edition:


    I think it may be on tomorrow night based on the previews that were on at the end of the show tonight.

  8. Lisa Allen says:

    George – Lol, that is a funny story! I have posted a few times myself after having some wine so I understand. I heard that Aeroplane Jelly theme song – it’s very cute and catchy. I guess what we call jello in the U.S. you call jelly? What you described sounds like jello. Jelly is what we spread on toast here. About the ballistic gel, or medical gel (same thing used for different purposes) I wouldn’t put it in my ear – I’d put in inside of something first. But right now it’s still in the plastic packaging and I’m just putting that between the pillow and my ear. Anyway I enjoyed reading your explanation – gave me a good laugh!


    • George G. says:

      Thank you Lisa,

      Is the gel still blocking the Hum? Perhaps random diary entries over the next week or so may be in order?

      Good luck with your experiment, and regardless of the result, at least you are having a serious attempt.

      The forum can only benefit from practical research participants such as yourself.

  9. Lisa Allen says:

    Hi George,

    Well, so far the gel that is most dense and most similar to human tissue (gel #0) works best, but when the hum is loud I have to put my hand under the gel pack, and apply a little pressure against my ear, when my head is on the pillow. Then about 95% of the hum is blocked. That does help me to fall asleep. The gel #5 (least dense) got into the washing machine by accident and flattened out, so I’m not using that one anymore. It was nice because it was softer but didn’t do a good job of blocking the hum. I also heard the hum with gel #3 and #4. I don’t remember what happened when I tried number 1 and #2, but I will experiment with them again tonight. The hum is not always the same volume (partly because I go to bed at different times and the later I go to bed the louder it gets) so a gel level that works when the hum is low will not necessarily work when it’s loud. I will report back when I have more info. on gel #1 and #2.

  10. annamaeforever says:

    Glen, I just wanted to say thank you, for all of your help. I saw the tv show and I was very proud of you. You were very professional and came across sincere. I know there were errors in the program but I am hoping that a university will somehow start to have an interest in it’s study. I believe that “it” will eventually affect all of us and not just a few. Thanks again.. Mary Ann

  11. Lisa Allen says:

    Last night I didn’t take anything to help me sleep, and the hum woke me up at 3:00 a.m. and I didn’t get back to sleep until after 6 a.m. So, tonight I finally cut one of my gel cubes (gel #0) into two small pieces, wrapped them in saran wrap and stuck them in my ears, and they seem to completely block the hum when I apply pressure to them. The only thing is that they don’t stay in unless I hold them. I’ll need to buy a tight headband and see if that holds them in place. I wouldn’t recommended doing this though. I’ll be the guinea pig and report back on how it goes and the condition of my ears after a few days of this.

    • annamaeforever says:

      Lisa, thank you for being the tester. My problem is that I have RLS and the vibrations trigger it in my right foot on the bed. Do you think if I get this stuff and put it in a bag and put between my socks with a sock over it it would stop the vibrations? I have just tuned the sound out since it is the vibratory issue that is so pressing for me. I’ve been going to bed with 3 pairs of socks on and a slipper to minimize the vibrations. If it is really bad I do take something light . I have always slept fine no problems until this thing came. I hate it and I call it “the hell monster” the “hum” does not fit it to me.

      • Lisa Allen says:

        Annamae, I think the gel cubes would probably feel uncomfortable using them the way you described, and I don’t think they’d help with the vibration, but of course I can’t be sure. You can buy anti-vibration pads online and put them under the feet of your bed, and see if that helps, though I did that and it didn’t seem to make much of a difference. But who knows, it may work for you. I’m glad you can get to sleep most nights without having to take anything. Is there medication for RLS? That’s got to be difficult to live with. I had trouble sleeping even before the hum and now it’s hopeless. I called a sleep lab today and told the guy about the hum. He had never heard of it before but looked up this website while we were talking. He’s going to have a doctor who is a sleep specialist call me. Last night I wore a bandana to bed over the gel in my ears, but it was uncomfortable after about 15 minutes so I took them out.

  12. Randy S. says:

    Has anyone experimented with noise-cancelling headphones or ear buds? I’m thinking ear buds in particular, if effective, might allow a good night’s sleep.

    • They have been tried, with mixed results. Let us know how they work for you.

    • Benoit says:

      Hello, I have experimented with the earmuffs, I bought a construction model with hard shell and very tight ring for maximum pressure.
      I removed the foams and placed several layers of aluminum foil, then put the foams back.
      The advantage of this experience is that we reproduce the calm of a bedroom everywhere outdoors.
      In some areas a few miles from my home I was able to separate from Hum.
      In the bed it is also effective because after a few minutes the Hum decreases by about 70%.
      Only discomfort is that you have to sleep on your back.
      This experience allowed me to understand that the Hum is the vibration noise of an internal organ generated by a phenomenon of external pressure variation.

      • annamaeforever says:

        Benoit, Did the vibration diminish in the bed also?

      • Benoit says:

        Yes, in the bed -70% but only after a few minutes, which confirms that the noise is inside and that after an insulation of the ears of a few minutes, the internal noise decreases. My wife had the same experience, and the result is the same.

  13. Lisa Allen says:

    One of the posters here (Dr. Menage) has had some success with that though I purchased the same thing and I could still hear the hum. I am thinking of trying the Bose noise cancelling earbuds, though I don’t feel very optimistic about it. If you find something that works for you, please let us know.

    • annamaeforever says:

      Lisa, was the sleep lab person any help? No, no acceptable meds for RLS. Is it mostly the sound that bothers you?

  14. Lisa Allen says:

    Annamae, the sleep lab doctor hasn’t called yet. The guy I spoke to on the phone said it might take him a few days to call because he’s not in but once or twice a week. If he calls I’ll let you know what he says. What bothers me is that I can’t get a decent night’s sleep because my current masking machines aren’t loud enough to cover the sound of the hum late at night, and I also feel and/or hear the pulse of the hum in my ear through my pillow. I definitely hear the hum because I can hear it over my noise machines, but that pulsing thing might be vibratory – I’m not really sure. I know you said the vibrations are what bother you most, but do you hear it too? Does it get loud late at night? I re-discovered that a stethoscope blocks out the hum. I wonder why? Too bad it’s impossible to sleep with that in your ears all night!

    • annamaeforever says:

      Yes Lisa, It is very loud at night and right now as I type it is 12:49 pm. There is also a banging sound and my house shakes with each bang. It sounds like a massive machine under my house. I can hear it outside sometimes too. I think we are talking about the same thing, vibrate/pulse.

      • Keith Hamlyn says:

        We have much the same. However, providing evidence to those who cannot hear it seems impossible. Have you (or anyone) found equipment that can record the noise. Most of the common ones make so much thermal noise in their front end amplifiers that the noise is totally drowned. Ideas and suggestions, please.

      • George G. says:


        Loud banging sounds followed by physical shaking of a house is well beyond the Hum’s capabilities—-it simply does not have the energy.

        Assuming you are not imagining (or hoaxing), a shaking house is a call for council investigation—immediately, especially if you feel the source is below ground.

        If some underground construction activity is underway, your house may suffer structural damage. The sooner you report it the better.

      • annamaeforever says:

        George, Sorry but you are wrong.

  15. Lisa Allen says:

    Annamae, good Lord, that is so horrible. I’ve been hearing a banging sound too lately, and I can also hear it outside sometimes. To me it sounds like the world is in a big, very old dryer, tumbling and rumbling away, all the time, with the occasional banging and droning of an old motor. I was thinking, I wonder if a hypnotherapist would be able to help by giving suggestions that make this not so disturbing. I quit smoking years ago using hypnotherapy so I know it can work. By the way, last night I turned off all my sound machines since they weren’t helping and pressed my sample gel #0 against my hear and couldn’t hear anything. Of course I couldn’t sleep like that but even having the gel pack under my ear helped some and I fell asleep (with the help of melatonin).

  16. Lisa Allen says:

    Annamae, I have heard the banging only at night a few times. I have wondered if there are other contributing factors to this, ie, the heat blowing through the vents, the airport runway being just a half a mile away, Air Force jets periodically flying overhead, a road with traffic less than a half a mile away and the ocean a mile away. The hum has a more or less predictable pattern most of the time, and I wondered if when there are deviations it is actually the hum or the hum plus other factors in the environment creating a new sound. I don’t know. A couple of weeks ago my husband closed the vents in one of the rooms and it seemed to make the air flow louder in our bedroom. It was loud and very annoying, as if the hum isn’t hard enough to live with. When he opened the vent back up the extra noise stopped. Do you hear the banging during the day, too? Do you live in an area where other external sounds could be altering or adding to the hum sound?

    • Benoit says:

      Be careful, do not mix all the noises.
      World Hum is a sound wave phenomenon that creates a continuous noise in our auditory system.
      Variable noises at various frequencies and therefore with beating are noises from industries, domestic machines and others amplified by the HUM phenomenon.
      I used the stethoscope by placing it on a coin. I discovered a slight vibration that after much research led me to an industry 8 miles from my home, large mixers were vibrating the ground. When they stopped for maintenance, more vibration in my house but the HUM is still there.
      The HUM varies more late in the night for the simple reason that starting at 5am people are getting ready to go to work.
      HUM is also stronger when the terrain is frozen. The trees, the meadows … become solid and promote the reflection of the waves.

      • Lisa Allen says:

        Could you explain more about putting the stethoscope “on a coin” and how that led you to finding large mixers that were vibrating underground? Thanks.

      • Benoit says:

        If you place the stethoscope on a hard floor, you will not hear anything because the slightly recessed membrane does not touch the floor.
        By placing a coin between the device and the ground you will hear the vibration. But this is not the HUM, it may be an industry or just the washing machine of your neighbor who is in spin mode.
        How did I find this industry 8 miles away?
        The vibration I felt was at 7 Hz. I did not have a device to measure so I took the keyboard of my computer and I pressed the “I” key with each beat for 10 seconds. I did 5 tests and I found each time between 70 and 72 beats. I then divided by 10 and found 7 beats per second so 7Hz. I reproduced the same experience in front of the factory and the frequency was the same. After contacting the managers of the factory who received me well but did not take my request seriously at first, because for them 8 miles it was impossible, I discovered in front of the factory that cable connecting two poles vibrated 7 times per second!
        When they stopped the factory for maintenance, I no longer had that beating at home!
        I thought at first that the HUM was this cause but after various experiences I discovered that it is the HUM that amplifies our ears, therefore we perceive the infrasound and beats at a great distance.

      • George G. says:

        You have an interesting theory Benoit, which could explain why a small percentage of Hum afflicted people experience so called vibrations, shakes etc. when others cannot.

        As you probably know, most Hum hearers only hear a hum but do not report vibration or shaking.

        Essentially, you are saying the Hum is a sound wave, which all Hum hearers are able to hear. Yes?

        Furthermore, you suggest the most sensitive amongst us also feel spurious background vibrations from various sources, such as industrial activity, as a direct result of this sound wave interacting with industry, thereby interpreting these spurious “beats” as a product of the Hum. Am I correct?

        Are you able, someway, to record this sound wave, this continuous noise, and present it to us?

        How do you detect this continuous audio source you confidently declares exists?

        By stethoscope, or microphone? Perhaps you could couple your stethoscope to an electret mic with suitable tubing and record it for us?

        An interesting experiment awaits, Benoit. I hope you take the challenge.

        By the way, good work by coupling a stethoscope to ground with a coin— you are obviously a dedicated experimenter.

      • Benoit says:

        Hello George,

        The stethoscope allows you to hear the vibrations of the ground. World HUM is not a vibration of the soil.

        I am a sound technician. I started hearing the Hum between 2010 and 2012, I thought it was machines working in the valley where a problem related to my profession.
        Over time this noise seemed to increase slightly but I could only hear it at home, not at work 14 miles away, maybe because the environment was noisier.

        In October 2016 I stopped working and found myself at home 20 hours a day, this is where the noise became permanent.
        My wife already heard it since 2013. A continuous sound like a transformer and at the same time there was a beat at 7Hz.
        After my first research started in January 2017 and mentioned in the previous article, so I discovered that the beat came from this factory 3 miles (sorry I mentioned 8 miles in my previous comment, small problem with my Km converter / Miles) and thought everything was connected as it was running 7/7 and 24 hours a day.
        After stopping for the maintenance of the plant I did not hear this beat for 4 days (from 19 to 22 June 2017) during which temperatures were around 32 ° C.
        Once these four days passed, the temperatures go below 26 ° C and the noise comes back but the beat is not the same, it is slower, I go back to the factory and I see that it is still at the stop and the cable does not vibrate anymore.

        In July 2017 I had the opportunity to test for a week the only sound meter able to measure infrasound from 1 Hz.
        I did 80 measurements in the valley over a radius of about 9 miles. I first measured the noise in my house and had a peak of 40 decibels at 4Hz. Then the most important noise came from old refrigerated units located on the roof of a supermarket in the valley where I measured 84 decibels at 4 Hz!
        I then studied the frequency converters present in refrigeration units and discovered that at certain speeds, the frequency variation creates harmonics that cause audible vibrations at low frequency.
        I thought for a moment to this theory because at 32 ° C the frequency converters are almost inactive, the fans rotate at maximum and therefore no harmonic and therefore no vibration.

        The second most powerful source was a 1000 MWe electric generator 1.9 miles from my home + – 70 decibels at 4 Hz.
        My conclusion was that each time the most powerful beat stops, the next one is heard, so it’s not rotating machines that create the HUM.

        A few weeks later, I decided to go to the quietest place in the country, away from industries.
        Arrived on the spot, no HUM and no beat. After a few steps in the forest, the HUM returns down a valley but no beat, just the impression of being near a transformer.
        A little later I returned to this place, a day when I had a headache and neck stretched. I heard the HUM everywhere! After an exercise pumping my heart, the HUM pulsed at the same time.

        I concluded that the Hum is internal, so it is impossible to record, some machines where transformers can reproduce a similar sound but as soon as you move away it decreases.

        I am convinced that a powerful and inaudible wave vibrates our auditory system that reproduces this vibration as the sound of a transformer and not as a diesel engine with flapping. This phenomenon stresses the muscles of the neck behind the ears.
        If I stay too long in my house, my neck tends and sometimes I can have a headache, if I travel, the neck relaxes a little and no headache.

        Why a wave?

        In my experience with the anti-noise helmet and aluminum, the HUM decreases after a few minutes in the bedroom, which means that a wave vibrates our auditory or auditory nervous system and after a few minutes minutes the system is under stress, the HUM decreases. However, the experience of the Glen box designed to stop the HF waves did not stop the HUM, so it would be a low frequency wave, but why then aluminum would reduce it in my helmet? Mystery!

        In the valley, in two places I manage to separate myself from the HUM after a few minutes with the helmet, if I go back, it is no longer possible to part with it. If I go further, he comes back. These two places are spaced 6.2 miles apart, in their center at equal distance is a radiological detection beacon and a little further away an army communications antenna. But … Nothing is certain …
        What is found on every point of the HUM map around the planet that could create this?
        Let’s continue to look for and benefit from everyone’s experience, to be able to communicate here between us is already a big step towards this mystery.

    • annamaeforever says:

      Hi Lisa, The county has been to our house several times to investigate the sound and pulse and banging. The banging sounds like water Hammer but much stronger and at night. Orlando is full of construction but that has been ruled out after several inspections. No pile doing at night allowed here. The power company has been here 3 times also we have transformers and under ground lines and that has been ruled out. The home insurance agent has been here twice and taken pictures of our house frame and all over inside and out to see if any structural damage from construction has happened. none. My daughter lives close and hears it very early morning and in one area of her house. The neighbor across the street hears and feels everything that I do including the banging but her partner feels or hears nothing. and has since moved. My neighbor down the street was here and I asked her to get on my bed and she did and she said she feels “a shaking.” The sound and vibration/pulse is constant and the banging usually starts at night. No construction pile driving at night anywhere near here. Heat is never on and everything has been ruled out, I could go on and on. The DOT was involved also. My friend in Me. hears the same water hammer banging also. There is only 1 thing left… Been here since 1977 and nothing until 2016. Love it here nu use to move it could come wherever we move. My family feels nothing only my daughter hears it. I was surprised to see so many spots on the world hum map so close to me. I wish I could talk with them.

      • Lisa Allen says:

        Annamae, the fact that your daughter and two neighbors have heard it too is significant. I can’t help but wonder if there really is something going on with your electric company (or some other industry) that they are not telling you, or, aren’t even aware of. If they were to admit that they were the cause of the noise, can you imagine how dificult and expensive that would be to fix? I’m not saying that that is the case, but I think it’s a possibility. And so few people complain that they probably feel no pressure to really investigate thoroughly. The next time I hear banging I’m going to pay more attention and turn the power off in the house and really listen to how it sounds. But it sounds like you’ve done everything humanly possible to get to the bottom of it. Are there many others in Florida who hear it, too? It would be interesting to talk to them if you could.

      • annamaeforever says:

        Yes Lisa and not just in Florida but very near my zip code, many dots. The thing with the power being the cause is, why my family members do not hear and feel it too except for my daughter? All those people who came to our house from the county inspection and the home insurance and the Duke energy people did not hear or feel it. My granddaughter lays on the bed with me and does not hear or feel a thing. And at the same time I feel and hear it. The neighbors across the street, she heard and felt it but, he didn’t. The neighbor down the street felt my bed shake but didn’t hear it or feel the floor vibrating. btw, You can check your immediate area on the world hum map page too by manipulating the dots.

  17. mark a Hayek says:

    2 theories i have for the cause of hum: 1. underground tunnelling, ,imig machines digging underground causing vibrations/
    2. pharmaceutical companies use large machinery in their plants which generates frequencies that travel great distances

    • annamaeforever says:

      Mark, your theories are very interesting and made me think a lot, but, it all still comes back to the question, why can only a few of us hear/feel it?

  18. Lisa Allen says:

    Benoit – that is very interesting. Good for you that you were able to pinpoint exactly where it was coming from – you are a good detective. But you say that, “I discovered that it is the HUM that amplifies our ears, therefore we perceive the infrasound and beats at a great distance.” But where does the hum comes from? Do you think it’s internal? I put a coin under the stethoscope on the floor and it did sound different than without the coin, though I didn’t hear anything that sounded like a machine. I’ll try it again sometime.

  19. George G. says:

    Thank you Benoit,

    I now have a better understanding of what you meant on your earlier post.

    I agree with you, I also believe the Hum is an internal manifestation.

    And thanks for sharing your experiments with us, every experiment hearers conduct and report helps others to develop and refine their experiments—all knowledge is good.

  20. Lisa Allen says:

    Annamae, a woman in my town heard the hum a few years ago, and it was a nightmare for her. Eventually she moved and doesn’t hear it now. She was sure it was a substation of our local power company (which bought her house after she moved, by the way). I don’t know if it was in fact the power company but in her case it could very well have been. If it’s a very low frequency sound, regardless of where it’s originating from, most people won’t hear it, so it could be the power company, but it could be many other things, too. That’s part of the frustration – just not knowing and not being able to track it down. Right now my left ear is completely clogged and I hate to say it, but I’m kind of thankful because I can’t hear as well now. That seems to be a ridiculous thing to say but it’s the truth.

    • annamaeforever says:

      Lisa, During the hurricane we were out of power for miles. I remember thinking in bed, well at least there is no racket. But then all the generators started a few nights later and I couldn’t tell the difference between the generators and the hum. I do remember it being so quiet at first. There is a sub station close to me but it has been there since 1977 and this didn’t start until 2016. I hope you feel better but until you do, feel the peace of quiet.

    Thank you, Annamae. I want to make sure I understand what happened during the hurricane: you’re saying that the hum went away when the power was out, correct? And when the power came back on you heard the hum again? If that’s the case, then the hum has to be caused by your power company or something running on that power in your area, doesn’t it?

    I’ve lived in the same house for 10 years and didn’t start hearing the hum until two years ago. I think something in us must have changed since the environment didn’t change, to our knowledge anyway. I read somewhere that we’re exposed to low frequency sound throughout our lives, and that eventually that constant exposure can effect our auditory system in a way that enables that low frequency to break through so we start to hear it. That would explain why so many people start hearing it all of a sudden, even though they’re in the same home and nothing’s really changed.

      hi lisa sorry caps key won’t work again. yes, the first night when the power went out I heard nothing, but, there are times when it is not here at all so I can’t be sure. the next day and night there was nothing I can remember laying in bed with no power so so hot no ac but saying, well at least theres no racket. it was quiet. the next day everyone knew the power would be out for over a week and so the generators started. they sound just like the hum thing. same sound and pulsing. very large generators were all around me and so I don’t know if it was here or not. I have called the power company, duke several times I have a transformer right out front and all power here is under ground. they came out and were here for many hours and said all is ok. at this present moment it is railing since last night at 2230 when it switched on like a machine. it is so loud and pulsing. I slept around 2 hrs after taking something at 5am. I am on my own and very scared there is no-one to talk to or call no-one understands they can’t hear it how can they I get it. I am trying to figure out what to do. if I believed this thing was internal I would be at the dr getting treatment, but I don’t. it is a machine and someone on this planet knows what it is. thanks for your support means a lot to me.

        Hiya Annamae,

        I don’t post here much anymore. But after reading your comment about you being a little scared by the dreaded Hum I felt that I should say something.

        And it’s this: 1. what Lisa just said, and 2. in my experience the Hum doesn’t do any much more than be a nuisance, and as far as I am aware it has never physically harmed anyone, although that said, psychologically it can be stressful.

        The Hum is weird, but as yet I see it as more of a scientific curiosity than something we should be especially concerned about.



      • I think this comment should be challenged. Even though I am fortunate enough to not suffer from the Hum, there are vast numbers of people who do. I’m assuming you’ve sampled the 17,000+ entries in the database. If you have, then surely you’ve read about how folks have suffered over the years. I might have investigated the Hum only out of scientific curiosity – and there’s nothing wrong with people who explore anything for that reason – but in this case, there is a real need to find the answer. I’m assuming that you wouldn’t also discourage the researchers who are getting close to relieving people from tinnitus?

      • Charlie says:

        I didn’t mean to appear callous. I have read enough on this site to realise that the Hum can be a very stressful experience for many people. It was just that the poster seemed anxious about the Hum and I was trying to alleviate her concerns.

        When I first became aware of the bizarre and seemingly anomalous characteristics of the Hum it made me feel quite anxious as well. Nothing in my world had ever behaved in this way before. The unknown can be a little scary sometimes. So I felt that in some way i could relate to Annamae’s concerns.

        I can see now that I took the wrong approach. As it was I was trying to reassure her (hopefully correctly) that the Hum isn’t actually physically dangerous. But by so doing it appeared that I was dismissing or trivialising the psychological impact that it can have. My mistake, I rushed in and based my post on my personal experiences. If I had thought about it I would have written it differently.

        I understand the argument that both tinnitus and the Hum are both self reported. That one is seen as an accepted mainstream condition, whilst the other can be seen as a bit fringy is a problem that needs to be addressed. I have tinnitus myself and the doctors have never questioned that. I don’t know how they would react to my reporting my experience of the HUm. For some reason I expect that if I did, it would be met with sceptism, a self imposed stigma perhaps.

        Hope this clears things up a bit.

        Charlie and Glen, Thank you both for your understanding and support.

      Your statements–

      “I think something in us must have changed—-” and—“That would explain why so many people start hearing it—–”

      rank as two of the most logical trains of thought I have read on this subject since the begin of the forum.

      Excellent logic.

  22. Lisa Allen says:

    Thank you, George. I don’t always succeed but I am trying to think about this logically.

  23. Lisa Allen says:

    Annamae, it might not be much help, but when you are scared and feel alone, try to remember that many people around the country and around the world are going through exactly what you’re going through. I’m up here in Myrtle Beach, just a couple of states up from you, hearing the same thing and trying to deal with it, too. I think if I lived alone I’d probably move, but maybe not. I don’t know.

    In my mind, everything is on the table regarding what could be causing it, including the power company, because we don’t have any absoluate proof, to my knowledge anyway, that any one particular thing is or is not the cause. So for now, I think it could be the power company as well as anything else. But just because they’ve come out to the house to investigate and claim there is nothing wrong, that wouldn’t convince me of anything. It may be beyond their ability to assess, and the fact that they don’t hear anything doesn’t help.

  24. Lisa Allen says:

    Annamae, I just want to make sure you know there is another area on this site where people also post comments. Glen just posted a chart called the Theorectical Logic Flow Map that Henrik created. You may find it interesting if you haven’t seen it yet. I’m printing out a copy now.

  25. Lisa Allen says:

    ….Then click on topics under “Recent Comments” on the left of the page.

  26. I filter out entries that include the sound being louder during the day, louder outside, and descriptions that don’t match. And also those who have made no effort to track down the source.

  27. Lisa Allen says:

    Glen – I was just surfing around looking at Hum info, and came across this which was a Facebook post:
    “Hi everyone, my name is Alexa Ginsburg – I’m reaching out from Inside Edition. We’re doing a segment about these mysterious hums people are hearing, the impact they have on your lives and possible theories behind them. We already spoke to and interviewed with Glen MacPherson but we’re also looking to hear from hum sufferers themselves. Please message me or email me at alexa.ginsburg@insideedition.com if you want to share your story – I think its incredibly important that people know they’re not alone! Thanks!”
    Do you think it’s ok to email her? If everyone did maybe they’d do a follow up story and be a little more serious about it.

  28. Lisa Allen says:

    I just realized that since this was posted before the show she’s probably not interested anymore in hearing from us. I’m tired and wasn’t thinking!

  29. Lisa Allen says:

    Today the hum is very loud; I fell asleep and actually had a strange dream about the hum. Anyway, when I woke up I turned my cell phone recorder on and pressed it down on my mattress to see if it would pick up any sound. As soon as I picked it up and looked at it, I saw that there were short vertical lines indicating sound along that sound spectrum line. I did that a few times and the same thing happened. That seems to be proof that it was picking something up, even though there was no audio. When I just held the phone in my hand it went back to a straight, flat line. Maybe this is nothing new, but I didn’t know my phone would pick anything up at all.

    • annamaeforever says:

      That is very interesting Lisa. It has been very loud here too since last night at about 2300. I had to put slipper boots on with heavy socks to sleep because of the strong pulsing. It has been loud all day and still now. I wonder about the cell phone. The pulsing is strong and the banging is present too. I will try and record it and see what happens.

  30. Lisa Allen says:

    Annamae, if you try this, make sure you press the phone into the mattress when the hum is the loudest. I’d be curious to hear if you have the same results. Regarding your feet, do you think putting pillows (those heavier gel pillows) under your feet/legs would help? I recently bought a couple of gel pillows (which are very comfortable by the way) and now when I sleep on my side I put a heavy pillow on top of my head and that blocks the noise I hear in the room about 75%, and then I have to position the pillow under my head away from my ear so I don’t hear/feel the pulsing. So far that’s worked better than anything else I’ve tried.

    I really wonder what it is about those of us who can hear the hum that is different from everyone else. We must all have something in common, but what? And why, out of the blue, did we just start hearing it one day? Is it just some oddity in our auditory system that was triggered by something? I wish we could figure that out. I have an appointment with a new ENT in a couple of weeks and I’m going to ask him what he thinks.

    • annamaeforever says:

      Lisa, I will look into the gel pillows. Last night I tried stuffing bubble wrap into my slipper boots and it gave me a barrier to the pulsing but still bad. I tried the phone but nothing, I will ak my family members to do it when they come over and see what they come up with. My grandchild is a geek. I do believe that this thing is real and for some reason we can hear/feel it. I think I understand the “internal” theory better now. I see now that the internal opinion means that we experience it but do not cause from our own bodies. ie, It is real. It is quiet now, I love it. Even my cuckoo clock is happy! I’m happy for you that you have found some resolution if even just a small amount for your ears. I think we have to keep finding the treatments for our own specific symptoms because I wonder if it will ever be gone. It is no use to move because it is everywhere and if I move it may come there. I love my home.

      • annamaeforever says:

        Lisa, I have a sleep number bed with two, 2 inch toppers on it. It is an adjustable bed and I have tried every position it has. I have oak hardwood floors throughout the house. I think you are right that it is everywhere not just the floor or bed. Its so quiet right now, where is it??? It will be back at 2300 hours tonite I guess. The logic Map is a great at a glance tool. Thanks for your prayer. Do you think you may bring a copy of the Logic Map to the ENT? That may be helpful. I have some questions about the Map that I want to ask Henrick. I guess I will try the pan of water experiment the next time it is railing.

    Got a better match to the tone from a different sound generator on sawtooth setting it is 48.888 Hertz G1 tone.

  32. Lisa Allen says:

    Annamae, isn’t that funny, last night it was quiet here, too. I hardly heard a thing when I was going to sleep. Today I hear it a little but it’s not loud. I wonder if a mattress topper would help to absorb some of the vibration you’re feeling. I used to feel the vibration alot more with my old bed. When I bought a new bed, it was too firm so I bought a mattress topper at Bed, Bath and Beyond that made the bed more comfortable, but also may be the reason I don’t feel the vibrations much anymore. I don’t know. I also believe the noise is coming from an external source but something unique about us allows us to hear it. I thought the internal theory was that there is no external noise and that our bodies are producing the sounds we hear. Is that wrong? Maybe I’ve misunderstood the posts that claim that. I hope the peace and quiet continues for you all day and night! I pray for you, myself and everyone here suffering from this.

  33. Lisa Allen says:

    Annamae, It is still pretty quiet here – I hope it is where you are, too. I think the pan of water is a good idea. I’ll bring the Logic Map to the ENT but also some info from this site; I want to show him there are thousands of people affected by this, not just me. Chances are he is not yet familiar with the Hum.
