For those who are able to, listen for the Hum over the next few weeks

I am in Covid-19 self-isolation now, having just returned to Canada from work-related travel through St Petersburgh, Helsinki, Kyiv, and Toronto. I feel very grateful to be back on Canadian soil. I am currently asymptomatic, and I wish good health to all those who may have been exposed or are working to limit exposure to themselves and others.

I received an email from a sharp-eyed reader who noted that over the next while, Hum hearers will be able to tell us if the dramatic reduction in world air travel is connected in any way to the perception of low-frequency noise and infrasound.

No doubt there are countless people out there who are overwhelmed with uncertainty and anxiety over much more important matters – issues such as the safety of elderly loved ones, putting food on the table, and whether they will have a job, for example. My empathy goes out to them during these extraordinary times. 

For Hum hearers who are safe, properly isolated, and have the mental space and need to keep their minds active, perhaps take some time at night to listen for the Hum. What you hear, or don’t hear, could add to what we know.

I urge everyone to help stop this pandemic and to attend to their physical and emotional health. For those of you who recognize a personal need to keep your mind engaged and focused, feel free to listen for the Hum, and tell us what you hear.

Take care.

    Blessings to you and yours. Reporting in that The Hum is as loud as ever, and consistent, here in Huntington Beach, CA

    Just one more thing making our heads spin.
    Stay safe and calm everyone.

      I live in HB and heard a hum for the first time in my life 3 days ago. Not sure if it was related to the naval boat that was right off the coast by the bridge between HB and Seal Beach. My girlfriend hears it too, also first timer. Louder indoors than out. There are multiple pitches, maybe 4 or 5 ranging over a very deep octave or two. The pitches seem to be pure tones like in a hearing test, but again, very deep. They also sound as if they would be harmonious, like all are notes in the same chord. The rhythm is usually a short huuh and a stop and then a longer (4 seconds?) huuuuuh and a stop. Pitch change, rinse and repeat. Louder at night, pretty constant throughout, although my fridge or other humms can drown it out. Not happy with this. Not sure if its a power plant or data center??

    Thank you, Dr. MacPherson, for sharing this suggestion and, more importantly, your empathetic words of encouragement and thoughtfulness.

  3. Elizabeth says:

    Thank you for reaching out to us Dr Mac Pherson. Yes I can still here the hum, and I have discovered a couple of things. First of all, if I listen to it in the same position people who meditate do when they ‘hum’ (sat down, legs crossed and head down), the hum is much clearer and louder. It also comes in waves just as the meditators do it eg: hummmmm … hummmmm…hummmmm. Hope this is useful information

  4. Thanks Glen. Same as ever here in Bristol, UK. What interests me the most are the times when the hum vanishes completely. Anecdotally this is rare, but it would be really interesting to somehow discover if there is any consensus for times when it’s absent. I’ve long thought about building a timeline based data tool, perhaps an app, for users to report no sound. Wishing everyone good health. Stay safe, physically, and mentally active in these extraordinary times.

  5. Olga says:

    Thank you for the good advice and well wishes. I am still out working more than ever as i am a grocery merchandiser. We are so busy right now, i think supermarkets are busier than ever. I havent heard the hum now for almost 5 months praise God. Wishing everyone health and sanity.

  6. Melissa says:

    Loud and clear, maybe even louder with ambient business and traffic noise reduced. From Woodland, CA.

  7. rgrsummer@gmail.com says:

    Thank you! I just noticed this week that it seems quieter. We live in Northern New Mexcio in an area outside of Santa Fe. Although I’ve had anxiety about the virus, I’ve had stretches of time when I felt calm and at ease. I’m thinking it may be due to the reduction in noise. I will pay attention tonight. Stay healthy.


  8. Jim Burton says:

    My mind went to exactly this question. Interestingly, for 2 days this week it was blissfully silent. Completely silent. However it is now back but with variations of rhythm – more monotone last night, but back to its old self today (around 50 waves per minute). I live in the UK, in the countryside roughly between Heathrow and Gatwick airports. I was hoping, and was briefly rewarded, that the reduction in human activity would have an equal affect. Sadly not for me.
    Take care everyone.

    • Hi Jim, can you remember which 2 days were silent for you?

      • Jim Burton says:

        It was Tuesday 17th and Wednesday 18th March. We’d just returned hurriedly from France, so perhaps I had tuned out whilst away? But it is actually at sustained peak volume now. Sad face.

      • j4ybe says:

        Thanks. The hum is very consistent at the moment for me too (I live in Bristol, UK). Luckily for me, a silicon earplug in my right ear really helps. Considering the reduced amount of traffic and general noise due to the lockdown, infrasound from these types of things seems unlikely to be the cause of what I hear. Can you let me know on here if the sound disappears for you at any point during this time? I’ll do the same.

      • Nicolas Fabre says:

        I often notice that when I leave my house for a few days, when I come back, it takes 1 or 2 days to “re-tune” to the hum.
        But once I am tuned I can’t tune off.

      • The intensity of the sound has noticeably reduced for me during the last few days.

        For the first time this year it disappeared completely on the morning of the 21st June. It was very low last night and this morning, still audible but much less prominent.

        There is a heat wave here in the UK for the next few days so I’ll keep an ear out. I remember noting a couple of years ago that the sound vanished during a week long period of extreme high pressure over the UK.

      • Jamie –

        It would be very helpful if you could give indications as to whether your hum is internal or external. Checklist here:

      • Hi Bernie. I am almost certainly sure the hum I hear is externally generated, coming through the ground.

        One major factor to me feeling this – the use of silicon earplugs either dampens or eliminates the sound depending on its intensity at the time.

        It is usually a consistent distracting volume, noticeable when quiet both at night and in the morning. The sound bears all the usual hallmarks, so I won’t note those.

        As I mentioned above, recently it has notably reduced in intensity, and on one occasion disappeared altogether. It was also far quieter last night and this morning again.

        While I’ve not been tracking / noting my anecdotal experiences scientifically, I have now started to record when the sound intensity changes or goes completely.

        I think it would be really useful to somehow correlate these notes with regional / localised peers.

        A brief story of interest. I hired an local electrician last summer for a bathroom job. I chatted to him about the hum and he was confident it was all to do with substations. He had heard it himself while living in one area, but not after a house move (both in the Bristol region).

        Back in February a substation very near me went offline. We had a brief power cut. Then while walking nearby I noticed all the maintenance guys installing a temporary fix. I stopped and enquired, a chap told me the transformer had blown rendering the sub inactive for a few days. During the time it was offline, the hum persisted. In fact I remember it persisted during the actual power cut and also during some brownout power cuts last year.

        While the seemingly 50 Hz range I hear seems consistent with electric, based on these few experiences, I’m yet to be convinced that is the cause.

        For what it’s worth, I just thought I’d chuck those in here.

  9. Lisa Allen says:

    Here in coastal South Carolina there is no change in the hum. It’s been especially loud though the last couple of days.. Wishing you a speedy recovery!!

  10. Dorothy Lebel says:

    Hi Glen, best wishes for your health. You are asking Hum hearers to notify you of Hum changes. Not sure if this is the appropriate channel to reply, if not please let me know which one.

    I am from Whitehorse, Yukon. I badly experienced the Hum for the first half of 2011. Then it mostly went away. But now for the past 10 days or so, the Hum has come back strongly enough to be very annoying. It is worse at night, but also happens in daytime.

    Due to my 2011 Hum experience, which spanned 6 months (i.e. 3 months prior to and 3 months after) of the Japanese earthquake, I associate the Hum to seismic stress, which is known to cause electromagnetic flares, and possible infrasound as well. So, in this current Hum experience, I wonder where and when exactly on the west coast this upcoming earthquake will occur.

  11. Peter J Wegner says:

    I am in Minneapolis, MN. I have been hearing the hum since I moved into my new place in the city. This evening I intended to meditate but the hum is making my brain feel massaged and not in a good way. I wonder if it’s the rail yard a few miles away..

    • lemon says:

      regarding how your brain “feels” or the pressure sensation on your head and sinuses, it may be due to EMF, or cell phone/ cell tower and WiFi radiation.. A test meter can be a great tool to read for such exposure, and you can take measures to reduce the intensit of this radiation in your envirnment, .. I suggest looking into this, as it may actually help to improve your mental and physical health 🙂 An EMF test meter is suggested.

  12. lemon says:

    the hum has been consistently louder for these past 5-6 days. I suspect that the hum that I hear, that began in Sept 2015, is likely caused by underground gas, or transmission pipelines coming down through and across the state (Michigan). VERY annoying and invasive resonating hum sound, It is an environmental nuisance.

  13. Danni says:

    I live in the flight zone of our major airport and even though flights have been reduced the hum is the same 24/7 since 2011 for me. It does sound louder but that is because of less land and air traffic to mask it, the quieter the environment is the louder it can be heard for me. Blessings to you, be well Glen.

  14. Gillian North East England says:

    First time I have noticed this in a couple of years here in north east of England. Very strong from early evening (25/03/20), then all through the night and early morning. Rising and falling in intensity, to an uneven rhythm. Stronger indoors than out.

    • Ian says:

      Hello Gillian, I too am in the north east of England. I first began hearing (suffering) the hum circa 1983/’84 (though at the time I didn’t know it as “the hum”…long story…). Since lockdown I have heard it at times almost unbearable (though I have largely learned to live with it and no longer take much if any measures to drown it out the decrease in ambient noises I think makes it more noticeable) – I think most of us now know for certain that this is entirely internally generated…

      • Mark says:

        “internally generated” is meaning what? I am curious as I read about this in The Invisible Rainbow by Arthur Firstenberger.

      • “Internally generated” means that one is not hearing a sound in the usual sense – that is, external vibrations in the air received in the eardrum, and so on. Tinnitus is also internally generated; it is an effect of the auditory system that nobody else can hear. We don’t know right now whether the Hum is a result of some type of environmental exposure, genetic-anatomical variation, or other cause.

    • Ian says:

      …not just in the evening for me – morning, noon and night – right now (13:21GMT) it is really quite intense and more like and much more like the drone of a small airplane going overhead than the usual idling truck sound (yes, I have just looked out to check it isn’t;)).

  15. Vincent Pêcheux says:

    My name is Vincent and I live in south of France.
    First, excuse me for my english, I try to explain my very new experience.
    For me, it started for the first time last week, right after the beginning of isolation in France.
    It was at night and I first though of a truck slowly running by my place. I leave in the mountain in a very quiet place. No industry around but usely planes in the sky.
    Also, I leave in a yurt without any electric stuff (no fridge…).
    I could not sleep during the whole night.
    Next nights, I spent my time looking for the origin of this noise. I seemed to come from every where and much more louder indoor than outdoor.
    Now I can ear it even on day but only indoor.
    2 nights ago; I decided to walk all around and I realized I could ear it anywhere, in different valleys so it could not be the same origin and I understood it was coming “from inside of me”.
    I googled “tinnitus engine noise” and I immediately found articles about the hum describing exactly in details my own experience.
    I felt much less anxious at this time and last night I decided to make calm inside of me and to really listen that noise.
    I discover 2 thinks :
    First, I can choose “where” I want to listen the noise : It can be in the whole environment around or closer to me, close to my hears.
    Then, when I really listen to it close to me, it is not the same noise any more : it sounds more like a pulsation, a slow beat like a wave going back and forth. And the most I get relaxed, the most I “go into” the noise, … I don’t know how to describe…
    I fell asleep and spent the most restful night since last week!
    I just hope I will be able to do the same next time!!!
    Does my experience makes sens for you?

    • Odree says:

      Bonjour Vincent, première fois pour moi sur le site, alors nous sommes deux! Je demeure dans le nord du Québec en région isolée. J’entendais déjà ce Hum avant, mais depuis la semaine dernière encore plus fortement. Je le ”ressens” plus que je l’entends, très spécial effectivement (la fréquence a laquelle je le perçois semble être +-20hz). Je n’ai jamais perçu ce son comme agressant, pour moi il a toujours été plus proche du calme et de la ”plénitude”, trés vibratoire. Je comprends votre ressenti.

      Hello Vincent, first time for me on the site, so there are two of us! I live in northern Quebec in an isolated region. I had heard this hum before, but since last week even more strongly. I “ feel ” it more than I hear it, very special indeed (the frequency at which I perceive it seems to be + -20hz). I have never perceived this sound as aggressive, for me it has always been closer to calm and to ” fullness ”, very vibratory. I understand your feelings.

    • Nicolas Fabre says:

      Bonjour Vincent, où est tu plus précisément ? A Castres pour ma part !
      Que penses-tu de mon hypothèse sur les antennes pour sous-marin ?

    • Elizabeth says:

      Bonjour Vincent,

      First of all, there is nothing wrong with your English, it is very good. I can see what you mean about it sounding like a truck. I had never thought about this, but yes this is a good description. I’ve been trying to work out why the sound in broken up. You would think if it was anything electric, mechanical or gas related, the noise would be continuous, but what I hear is broken up in bursts of noise. It’s almost like how morse code is. Do you hear it like that? It can be like this : hummm hum hummmm hum hummmmm hummmmm hmm

      • Henrik says:


        Your interesting description points to man-made noise somewhere in your environment. Try to make notes about the length of the bursts (how many seconds for ‘short’ and ‘long’, how regular?), any silent periods (‘lunch breaks’?), what time of day you hear it, weekdays vs. weekends, etc. And try to determine the frequency of the sound – see the home page of this blog. That could give you some clues to what activity produces that sound. Low-frequency environmental sounds that are heard only, or mainly, indoors, are often transmitted by ground vibrations, and the source may be many miles away.

      • Henric –

        My reaction to Elizabeth’s “hummm hum hummmm hum hummmmm hummmmm hmm “was that it STRONGLY supported the notion that hers was a traditional (internally-sourced”) case. The HUM does generally occur with amplitude fluctuations or about ½ sec to 2 sec – hence the very common description as a diesel truck idling (surging) instead of a stationary “buzz”.

      • Henrik says:


        To my knowledge only the heartbeat holds a steady rate of approx. 40bpm (0.7 Hz) to 120 bpm (2 Hz), and the related blood pressure variations can modulate the internal hum correspondingly to make it sound like an idling engine. But unless a person has a severe arrythmia, that should not sound like a morse signal.

      • Elizabeth says:

        Henrik and Bernard, thank you for your comments, it’s nice to get such good feedback. I will keep and diary and let you know the results. The noise I hear is very faint, as though it’s in the distance. I have to have complete silence to hear it. Are you the same?

      • Henrik and Elizabeth –

        The amplitude variations in “The HUM” (for me at least) seem to involve “connected segments” that seem randomly associated and of lengths ½ sec to 2 seconds and perhaps depths of from peak 100% down to 50% between segments – NOT in ANY way related to something as nearly periodic as a heartbeat.

        It is these amplitude fluctuations that invite the comparison to an idling diesel engine which “surges” to avoid stalling on its stingy standby fuel ration.

        While listed as item one (of eight) of my “HUM checklist”

        Click to access ENWN53.pdf

        I don’t recall previously recognizing the surging comparison as the nexus; HUM vs/truck. Thank you Elizabeth!

        Elizabeth – if you are so inclined, consideration of all eight items on my checklist should settle the matter.


  16. Nicolas Fabre says:

    These days, like almost all of you, I am obliged to stay in my home here in Castres, southern France.
    I can hear the hum all the time. My only trick to get a bit of rest is to put my finger in my left hear ! Try it, it works for me !
    But to be serious… what is the most likely current assumption?
    For me, it is these large radio communication antennas, to communicate with submarines.
    It uses extreme low frequencies, and produce a signal that has to spread all over the world, until the ocean’s floors.
    I believe that when armies will stop using these antennas, hum will stop.

    • Jeanine Lyons says:

      I have wondered if the Hum is something military related, as well. I was thinking maybe a missile shield of some sort. However, the idea that it might have to do with submarines, makes A LOT of sense!! When I lay down on my pillow, it’s as if there are generators running in underground tunnels. It’s as much of a vibration as it is a sound.
      When people use sound frequencies to get good sleep and meditation etc, it makes you wonder what bad frequencies can do to the body and brain. We KNOW how disruptive this him is to sleep! God bless and stay well🙏🏼

    • Anne-Sophie Lefebvre says:


      je suis en Seine et Marne, région parisienne, et j’entends le Hum depuis 2 ans. C’est un véritable calvaire, je n’en peux plus. Comme vous c’est en bouchant mon oreille gauche que je peux le masquer.
      Votre théorie sur les antennes pour sous-marins est intéressante, savez-vous où trouver une carte de ces antennes ? Comment les repérer dans son environnement ? Il va falloir que j’envisage de déménager, mais rien ne sert de déménager si c’est pour l’entendre ailleurs, d’autant plus si la portée de ces antennes s’étend sur des dizaines de kilomètres…
      Merci beaucoup

      • Nicolas Fabre says:

        Bonjour Anne-Sophie,
        Vous avez une liste des antennes ici : https://sidstation.loudet.org/stations-list-fr.xhtml
        Mais … 1/ ce n’est pas sûr que ce soit ça la cause et 2/ ces signaux font le tour du monde donc je ne pense pas que la proximité avec les antennes joue vraiment.
        Le déménagement est une option à bien mesurer, il faudrait pouvoir passer plusieurs nuits dans le nouveau logement pour juger de son exposition ou non au hum.
        Pour moi la meilleure solution est l’acceptation paisible… et le doigt dans l’oreille gauche 🙂

      • Anne-Sophie Lefebvre says:

        Merci beaucoup Nicolas,
        Le doigt dans l’oreille gauche… je n’en peux plus, c’est si inconfortable…
        Je regarde de plus près ce site internet, merci encore et bon courage.

  17. Renee says:

    I live in Colorado Springs, CO and started hearing the hum 5 years ago when I moved to this city. The state of Colorado is on a stay at home mandate since 3/26/2020. This has dramatically reduced both auto and air traffic, however the hum seems even louder than usual. At times I can almost feel a slight vibration and it hurts my ears. Needless to say, I haven’t been sleeping well.
    I recently found information about the Schumann Resonance and will try to keep a log comparing the intensity of the two. I’m planning on moving in an attempt to live somewhere quieter.

    Thank you for your continuing investigations.

    Stay well.

  18. Lotte Bering says:

    Hello. Here in Denmark I definitely feel that the hum is considerably less intense. This despite living in a cottage area where the many heat pumps have just started. And the whirring vibration I usually feel in my mattress at night has almost completely disappeared. I enjoy the silence and the blue sky. My hope is that humanity as a whole will decide on a new way forward. Thanks for your efforts, take care of yourself. Warm greetings from Denmark.

  19. Eddy Nico says:

    I live in a small ski resort in the Italian Alps which has had absolute silence since our lockdown on the 9th March especially at night when not even the birds tweet. . The hum has become much louder since then. I can only hear it indoors, even, at night and am the only one in a family of 7 living on the same property that can hear it. In the next few days I will try and check if I can hear it in other buildings in the village and ask other people living in the village if they can hear it. I’m thinking of trying to sleep in a tent in the garden to see if I can get a good nights rest. I will post further observations on this comments page.

    • Nicolas Fabre says:

      For my sake, I can hear it day and night, inside and outside.
      But until now, it does not hinder me to sleep. My advice is to just accept it like it is. I think it is not dangerous for health, it just can cause anxiety, that will have other consequences like problem to sleep.
      Feel lucky to be one of these persons that can hear this mysterious hum!
      One day, we will find the root cause.

  20. Franco says:

    Hello to all, I hope this covid19 isolation may stopped quickly! I go out of my mind with this infernal hub. I live in Padova, Italy, near Venezia, in a isolated country.Every time and everywhere I normally have an escuse for this sound: the traffic help me to justify, indoor and outdoor.But there’s no traffic now! For job I travel by car, so I have not problem. But now I must live at home whit this pc always on (even where’s no pc), or this engine truck or tractor that works at a long distance. When you’ll find the remedy for this evil, even if it’s an hammered on the head, call me please. Bye. Franco

  21. Kurt says:

    no hum here in South of Denmark for weeks, been troubled by this for20 years

  22. Lisa Allen says:

    In the last four or five days I haven’t heard the hum either in Myrtle Beach, SC.

    • Lisa –

      Here, with me in Ithaca, with the general (noticeable) reduction of distracting environmental (largely traffic) noise, due to recent travel restrictions, the Hum is more distinct and thus a bit EASIER TO HEAR. Same level as what I have heard for 25 years. Certainly not gone.


      • Lisa Allen says:

        Bernie, that’s how it was for me too in the beginning. Now for some reason, I’m not hearing it at all. Maybe I’m having a problem with my ears, I don’t know. Time will tell.


      • Elizabeth Colley says:

        This is really strange today. The hum has totally changed. It’s not there all the time, but in burst every 30 seconds – 2 minutes and sounds just like a fog horn (hummmm … hummmm… hummmm…hummmm—————————- hummmm…hummmm…hummmm…hummmm). Very strange!

  23. Martin Vane-Hunt says:

    Hum in Moncton, New Brunswick. After ten years, it has changed its tone for the first time – it’s slightly higher pitched than before, maybe three whole notes, but still a bass tone. Volume has not changed; as loud as ever. I’ve heard this same hum all over the world, China, Europe, All over N. America.
    First time it’s changed at all – just a slightly higher pitch. I did tone matching
    to find the frequency in hertz before in Europe; if I can find that data, I’ll try to compare with the higher-pitched sound now.

    Test of terrestrial origin: send someone who hears the hum into space. Have any astronauts been “hummers”?

  24. Josh says:

    I am hearing it loud and clear here in Germantown Maryland. I notice it outside as well as inside.

  25. Catrina says:

    I finally looked up that strange humming noise i been hear on occassion looks like other hear it too. And though i havent recorded it yet. That is next on my list to campare with other hums. It spunds similar. I heard it again late afternoon here in Huntington Beach Ca today april 9,2020 it lasted no longer than 10min but longer than 3min. Guestimate base on cigarette break. What r some methods people have tried to originate where sound is coming from. What kind of meters, gauges, cameras, and other electronic sensory equipment has been used?

    • Jeanine Lyons says:

      Hi Catrina, I am in Huntington Beach, CA as well. I have tried to record the sound, but it can’t be done without a special meter. Not sure what that is, but it’s more of a vibration than a sound.

      I use a sound machine on my phone to try to drown it out. I wear ear plugs, but sometimes they make it worse. It stinks that you have to make noise to mask noise.

      It’s actually ramping up as I type this at 10:30 pm on April 10. Sometimes it gets so loud during the night, it sounds like our whole house is vibrating. The WORSE part is not knowing what it is coming from. It is NOT tinnitus. 3 people in our house and house guests, ALL hear it. It is not the telephone lines or transformers.

      Whatever this is, sounds like it’s coming from the pipes underground. It’s like there are big rig truck generators running ad making the ground and walls vibrate. SO ANNOYING.
      It’s very hard to hear outside. People out in the middle of nowhere hear it. We’ve heard it in the mountains as well. Everyone says the same things, ESPECIALLY that it is unnerving and disturbs sleep.

      • dwest999 says:

        Hi, I’m of the opinion (after reading and testing myself) that the hum is a vibrational thing that some of us “hear” through our bodies, and which resonates onto the ear drum. After doing research, this is my conclusion. I believe most of us are picking up whatever it is (wave forms of a certain wave type) that triggers the ear drum or hearing in the brain. (The senses for seeing and hearing are complicated in the brain, and can be switched around in a sense…very unscientific paraphrase for what I’ve been learning.) Anyway, the “sound” is not there audibly — as when going outside to figure out what it is, it’s not there; and others do not hear it. So, I’m with those that think certain waves (like submarine waves) can be picked up by the body and transferred through the body to the brain, which we associate as hearing. (My high pitched tinnitus that I’ve had for 20 yrs. does not stop when I do the fast deep exhale test — but the giant hum ceases for a nano second or two — as described as a comparison test in the mapping project — when we describe the phenomena in that tool.) So, it’s interesting to think about what sorts of underground things are happening, that cause certain sound waves that our bodies are picking up? I’m now entertaining some way out their theories!

      • Dwest999 said “the giant hum ceases for a nano second or two”. Since a nanosecond is 10^(-9) seconds, imperceptible in human perception terms, I assume he/she means nanoseconds in the “ INFORMAL: a very short time; a moment” which would seem to include ½ second within the human perception scale of “just-noticeable”. Accordingly, your observation is consistent with the traditional (internally sourced) HUM.

        Do you agree? The comment “others do not hear it”
        also suggest a personal (internal) source.

        Click to access ENWN53.pdf

        It is unclear that these likely observations are consistent with some of the rest of the comment. For example, Dwest999 also says “I believe most of us are picking up whatever it is (wave forms of a certain wave type)”

    • Eddy Nico says:

      It can be measured in Hz and determined whether originating from the inside of ones home or from the outside using the methods described on this website but as far as tracing the origin I have not been able to locate it. I’m not sure but I can’t seem to find any method on this website or any other in fact on how to find the origin of the hum noise many of us hear. I’ve found another mobile app that is not mentioned on this website that is much easier to use as far as registering the Hz level of the noise. https://play.google.com/store/apps/details?id=com.julian.apps.VibrationsAds&hl=en

      • Nicolas Fabre says:

        Using this app it points to 49.3 Hz for me, what about you and others ?

      • Eddy Nico says:

        Using the Vibrations app is mentioned mine is not a constant reading and fluctuates mostly between 82Hz and 86Hz with sporadic periods when it shows 48.8Hz. There is another reading on this app which is a vibration reading and this seems constant at 5.6Hz. I have not idea what all this means but at least I know it’s registering something. We now need some help in tracing this noise/vibration. I have not found an app or way to date and the website does not give any indication of how to do so either. The website only suggests a way to determining whether it’s inside or outside but still does not tell one how to trace it and seems to only be interested in wanting reports from inside generated noise. It also goes on to say even if readings point to the noise being heard inside it could still be coming form the outside. So in all not very helpful in tracing origin but very helpful as a website to exchange ideas with each other so than you to Glen Macpherson for his efforts in providing the website.

      • Nicolas –

        It is not clear from your brief description whether you used the app to measure the physical frequency of an already (meticulously achieved?) pitch-matching effort of the hum YOU ACTUALLY HEAR or if you have used it to simply assay the background sound in the environment. Apples/Oranges. This is an important distinction to resolve, I think.

        49.3 Hz as electrical/acoustic noise could likely be related to your 50 Hz power frequency (essentially everyone). You might well not hear the environmental 50 Hz very well while “hearing” (perhaps) 64 Hz as a PERSONAL internal hum that your instrument is of course NOT picking up at all.

        Hi, first my apology for not being able to find how to post right after the last poster (Bernie) — to connect our conversations.

        Yes, Bernie, nano-seconds was my slang. The hum stops a half a second upon quick inhale & exhale.

        By the way, I reported the hum stopped suddenly during our COVID-19 shutdown; but it only stopped for about a week. It came back & as before, never stops. (I can even hear it sometimes early evening if the house is quiet.)

        What’s interesting, only on a personal level, is that it was annoying the first week. Then I learned to ignore it (similar to my tinnitus), I could get to sleep by ignoring it. But this past 3 to 4 weeks, after accepting it as part of my life, it has become a comforting thing! I’m amazed. (Not quite like my belated cat’s purr, unfortunately, but nevertheless, comforting.) My only explanation for this is that is, in my opinion, definitely qualifies as a biaural beat: Biaural beats are when at least two tones are close in pitch, and sound between at least the two (or more) tones rapidly; this causes the brain (in simple terms) to shift into alpha or theta relaxed states: “…By exposing the brain to beats that create low-frequency tones in the brain, these sound waves create shifts in brainwaves themselves, generating slower frequency brainwaves that promote deeper states of relaxation…” source: https://www.psychologytoday.com/us/blog/sleep-newzzz/201810/how-can-binaural-beats-help-you-sleep-better

        Anyway, it dawned on me this past month, when the ‘giant hum’ machine like tones became comforting, that they were, to me biaural beats. (They seem to qualify – low frequency beats alternating between close pitches.)

        Anyway, the hum is back; is has not changed in the sound; and it remains as before, low somewhat machine-like sound.

        My apologies – I haven’t tried testing tools as noted in the discussions. (I did the first night it showed up last fall – as it was so alarming and frightening; only used a phone app, and I assumed I was picking up ambient noise that every house would have.)


    • Charles says:

      Also in HB, heard hum first time a few days ago. Posted near the top with more of a description of what my girlfriend and I are hearing. multiple pitches and durations. It’s almost more noticeable or disruptive when the hum stops than when a mew one starts.

  26. FP says:

    Here near Boston I actually noticed the hum has completely disappeared.
    Absolutely gone! I usually wasn’t very annoyed by it, but could hear it. Now absolute silence, what a pleasure!

    • Nicolas Fabre says:

      You are lucky ! 😀 could be interesting to have some testimonies of other people in Boston … please tell is if it comes back !

    • Kurt says:

      same in south of denmark, completely gone after the lockdown, been trubled for 20 years, now complete silence for 3 month

  27. Donna Cariola says:

    I am new to this and have been hearing the hum for about 3 weeks now while lying in my bed in the middle of the night. I can’t hear it outside.
    It sometimes wakes me up. It is not every night but at least 5-6 times in the past 2-3 weeks.
    I am in Pennsylvania close to the central New Jersey border. It is particularly loud today.
    I am glad I found this site. I thought I was losing my mind!

  28. Kurt says:

    I write once more, no hum since the virussituation startet in south of Denmark ( Svendborg) I have heard it constantly for 20 years, now no sound at all since lockdown. I sleep tight, no nightmare or anxietys, like being reborn

    • Nicolas Fabre says:

      Very interesting reply, advise us at the end of the lockdown to see if the hum comes back ! For you I hope it won’t, but if YOUR hum is related to human activity nearby, it could…

    • Henrik says:


      That could be an interesting observation. Could you please write down any possible changes you noted in connection with the beginning of the lockdown? Did you live all those 20 years in the same house? Was your hum continuous 24/7, or was there some periodicity? Is there a restaurant or other establishment nearby, which had to close their business when the lockdown was imposed? What did you change in your own daily routines or eating habits, medication or supplement intake? And especially, when the lockdown is over, does the hum come back? When the lockdown is over, please present your findings here, under the same thread.

      • Kurt says:

        I will, and no nothing has changed in my surroundings, and yes we have lived here for 17 years. We had to move from another house due to the hum. But the Hum is all over the place. The Hum normally comes and goes, worst at night. It is the hum I hear, absolutely no daught about that.

      • dwest999 says:


        I think I posted that the hum only stopped for one week during shut-down.

        It’s the same as before…as always, since I first noticed it in Fall of 2019. I can see a cell tower from here (250 yds maybe); some small businesses about 50 to 75 yds away on main road. During shutdown, when no traffic whatsoever, I could still hear it. (I can hear it during the day when in a quiet room of house; not as easy to detect during day…being near a road.)

        Note: I stayed one night at family’s — 30 minutes east of this area — I heard the hum there, too. (This other area is not near businesses, just condos, with woods behind the units.)

  29. Lindsey says:

    I’m new to this issue. I am from the USA, and am in Plymouth, UK (was backpacking the world and got stuck here when the lockdown happened). I never had heard this hum sound until last week. I have even been in the UK for a month now. And it wakes me up every day around 3 or 4 am and is soooo loud that I can’t sleep. I keep expecting a car to be idling outside or a helicopter over my building. By the time I wake up at 7/7:30 it is always gone. But I am starting to dread going to sleep at night, because every night I wake up in the middle of the night and feel so anxious like something is happening outside my window or above me.

    I am 33 and have no health problems at all. I don’t, and have never, taken any medication for anything at all.

  30. Debecker Caroline says:

    Hi… from Belgium. Here we are in lock down for more than 4 weeks.
    But The Hum is as loud than before. Perhaps even it seems louder than ever. My sleep is highly affected, it feel like my brain was wounded by this vibrations. Just one point, I notice the Hum seems more « constant » (less « wavy »)

    Best wishes to all of you.

    • Kfeto says:

      Hi Caroline,

      Where in Belgium are you and how long have you been hearing it?
      I myself am in Maasmechelen and have been hearing it for 4-5 yrs and getting louder.
      Pretty sure it’s interference from the windturbines they erected here.

  31. MR says:

    Belgium too, here. Hearing this l’oud vibration at night, feels like it’s getting louder as the night progresses. 3 am, and i can’t get no sleep. If anyone has found a solution to ‘un-hear’ it, i would be glad to know, because it’s driving me buts. Cheerd

  32. Lisa Allen says:

    MR, the only way to “un-hear” the hum that usually works for me is to do two things: mask it with background noise such as a sound machine or using a site like this: https://mynoise.net/NoiseMachines/rainyRiverbankSoundscapeGenerator.php?c=0&l=7369567636231720222400; and positioning your head between two pillows so that your ear is in the space between the pillows. I also have a small travel pillow that I put on my head and that helps me too. hope this helps.

    • Nicolas Fabre says:

      Just put your left hand index finger in your left ear, it is not comfortable but it works.

      • MR says:

        A moins de pousser sur les deux oreilles avec les deux index, ça marche pas. Difficile de dormir comme ça. Après plusieurs nuits où j’ai pu dormir, nuit blanche cette nuit. 5h50 du mat’ et la vibration est incroyablement forte. Je sais pas à quoi ça tient, mais des nuits comme celle-ci, c’est très très compliqué….

  33. emilie says:

    Resume for english people: i have a problem with Hum in the north-east France. Sorry, but it will be more easy for me to speak in french language. J’habite dans les Vosges. Depuis mon emménagement à Charmes il y a 3 ans, j’entends le Hum de jour comme de nuit avec des variations d’intensités. Hummmmmm Hummm Huuuummmmm Hummmmmm… que c’est lassant et pénible. En ce moment, depuis le déconfinement, ça a bien repris, ça me fait mal aux oreilles surtout la droite. Je me demande si la maison ne fait pas caisse de résonnance aussi car dehors je ne crois pas l’entendre. Mon conjoint lui ne l’entend pas (tant mieux pour lui mais je me sens un peu seule vous voyez…). Trouver le silence est difficile surtout que nous avons beaucoup de voisins qui nous entourent, c’est rassurant d’un point de vue sécuritaire mais chacun y va de sa tondeuse de compétition, de son portable avec haut parleur… Bref. Le bruit + le Hum c’est fatiguant. Je ne sais pas trop d’où vient ce bruit, c’est mystérieux, nous sommes dans une zone a potentiel sismique, mais aussi avec de la circulation un peu partout bien que nous ne soyons pas vraiment en ville…

  34. Kurt says:

    I can again confirm that the HUM is still gone, after 4 month still no sound. Ive been hearing the HuM for more than 20 years in various parts of Denmark and it has more or less ruined my life, and now its gone. I disapeared with the lockdown. Im a happy man 😊

  35. JO says:

    I found in the past, the more I focus on the hum, the louder and more frequently I experience it. So over the last couple years I’ve done my best to ignore it and in that method, it is more tolerable. I didn’t see this post when it came out originally, so I can’t add much of value.
    Last night though, (4/1/21 3:00AM) it was very loud. I will add here that just in the past week, I’ve noticed an increase in airplane take-offs from our local and small airport. 737 size aircraft are the bulk of the planes coming and going.

    I no longer think the hum is an external source. But I’ve looked at the map and it seems to be by far, the most prevalent across the US and the UK. Perhaps there is something going on genetically with those of Anglo Saxon descent? Perhaps a question on the hum map about ethnicity would reveal something?
    Or perhaps something in our common (UK-USA) environment like wireless routers causing some sort of harmonic frequency with the hair cells in our ears? Or something similar.

    One other thing, I’m a scuba diver and all divers know how to clear pressure from their ears when diving. Usually you hold your nose closed with thumb and finger and gently blow to clear the pressure. But there is an adaptation to that technique call Valsalva where you clear the pressure without pinching your nostrils closed. You simply move your lower jaw forward and it’ll make your ears pop. Probably everyone has done this instinctively when driving over a mountain pass. So I noticed, if I do this and sort of hold it, I do not hear the hum. It sort of make a sound of “fluttering” in my ears and completely blocks the hum. This is what lead me to believe this was an internal rather than external source.
    For me, the “head shake” did not stop my perception of the hum.
