Hi. There is an effort over this weekend to document any Hum changes in real-time. A few people are trying to correlate such changes with current astronomical and geological events. Thanks.


  1. Keith Dobson says:

    Just been tuning in the (Somerset, UK) hum to the online tone generator, as it’s quite boomy this morning. It is ringing at 54Hz to 56Hz. There are lower booms in it is well, but they are much harder to pitch by ear. I think they are the ones which cause the ear-pain.

  2. Csaba M. says:

    I can hear the hum quite loud and intensely these days in Amsterdam.

  3. Eileen M Bowie says:

    If you are still collecting information about hearers perceiving changes in the hum, please note mine: For the past few days (this is February 4, 2018) I have noticed that the hum here seems louder, but also a little higher in pitch and faster in pulse. I live in southern Oregon and have heard the hum for several years. I’m already in the data base. Thanks, Glen, for your steadfastness.

  4. Lisa Adams says:

    I have heard the hum off and on for about 8 years and just thought it was caused by a motor running somewhere. I recently moved and the hum continued. Last night it was very loud and then I realized it had to be something more than a motor. I had no idea that others have had this same experience until I searched the web about it. It is nice to know that I am not the only one.

  5. Eva says:

    I am very familiar with the aeroplane sounds as I live near a flight path. What is very strange is that many late nights in bed, I will hear what sounds like the plane is suspended over my home . I have actually gone outside to look where the plane is.. but nothing.. quite often I have gone to sleep with that sound as I give up looking for where it may be coming from. A few years ago I used to hear what sounded like a car engine running outside, but Dr told me this was probably my ears!! 🤔 that has stoped long ago.. this loud sound is def outdoors , as it gets louder when I open windows or doors seeking the source. I found this site by accident and I’m glad I am not alone thinking I am crazy! I live in the lower mainland, British Columbia .

  6. Rachel says:

    I’m not certain if you’re still interested in knowing where hums have been heard, but I live in Anacortes, WA and I’ve been hearing the humming sound as recent as late last night, or early this morning (6/30/19-7/1/19). I never looked at the time, but I suspect it was between the hours of 2am and 3am.

  7. Lori says:

    I have been able to hear the hum continually for the last three days, October 25-28 in Pennsylvania, USA.
    I first noticed the hum in 2016 and it usually subsides in the spring, at least to less noticeable/tolerable levels. I was working with an acoustic engineer who thought my next door neighbors pool pump may be a factor, but we were unable to test his theory as the neighbors were uncooperative. They have a tremendous amount of electronics in their backyard including a surround sound stereo system with speakers on their roof and several on the ground level along the interior of their fence line.
    I also have power lines which run the distance horizontally along my property line. These include Met Ed, PPL electric, Verizon and Comcast.
    The hum usually picks up to intolerable levels in the fall, late Sept or October and continues through April/May.
    Since I am new to this blog, any suggestions of how to locate source, including materials or equipment needed would be appreciated.

    • Henrik says:

      Dear Lori,
      The information and instructions you are looking for can be found on the website http://www.thehum.info, from which there is also a link to this blog. The most important first step for you is to determine the exact frequency of what you hear, and to establish whether you always hear the same frequency. The second step is to determine whether the source is external/environmental or internally generated in your head (or an occasional mix of both in some situations). If it is external, use the Spectroid or similar app on your smartphone to trace the source.

      • Lori says:

        Hello Henrik,
        Thank you so much for all the information. I had my hearing checked because of this situation, and was told I have perfect hearing, no issues. I do know that twice the humming coincided with solar flares. I will look at the http you sent to me and go from there. Thank you so much Henrik. Lori

      • Lori says:

        Henrik, One last comment – I am aware of the hum all the time. When it’s at a lower level it does not bother me. In fact, I can tune it out. It becomes intolerable when it intensifies, as if someone just adjusted a dial from volume 3 to 9 or 10. I just looked at the http you sent to me, and this appears to be what I am experiencing. I will investigate further. Thank you again, Lori

  8. John says:

    Has anyone noticed a change to the hum recently? I’m hearing a change in pitch in a repeating pattern – starts off at one frequency, then goes deeper, then back again, and keeps repeating like that?

    • Matthew says:

      not recently in the past few months but I have noticed it before.

    • George G. says:

      Hello John,

      Yes, this happens to me also, and I blame aging. When I first became aware of the Hum it was a constant pitch, and remained so for more than three decades.

      Now days it shifts abruptly from ‘normal’ to lower pitch and stops, only to
      repeat the sequence again and again. I might add my blood pressure
      medication had been modified around the same time.

      Please note others have reported this effect throughout the course of
      this forum, describing it as a foghorn sound, therefore I do not believe it
      to be an external source which has recently changed operation, but an
      affliction which changes with age, medication, etc.

      In my case I sense it from my right regardless where I am facing, therefore I assume the cause is an old injury to my right ear.

  9. Matthew says:

    I live in Alief, as subburb of Houston and have heard the hum noticably since 2018 in San Leon, TX. It’s loud as I write now but do not find it irritatating or unbearable, just annoying. What about electromagnetic radiation? I’ve not heard anyone suggest it in what I’ve read so far from articles I’ve read. I would really like to know the results your box offers. I’m using spectroid now and have calibrated it using test tones from youtube at 60hz and 432hz. The readings I get are 47 hz at 101 db and 439hz at -77db. I am almost certain I’ve heard this hum as a child laying in my room in another suburb of Houston,TX Thank you for your work thus far. It’s refreshing to know I am not the only one. Also, I am an Ambidextrous male of 50 years old diagnosed with schizophrenia at age 48 that takes his meds daily. I rarely drink soda. I have age related hearing problems probably from listening to loud music from concerts growing up. I also have tinnitus in both ears.

  10. Jill says:

    I have been aware of hearing a persistent hum for at least 10 years. I am on a Gulf Island in the Salish Sea, B.C. It is sometimes louder than other times but does not seem to change in pitch. I have personally labelled it the noise of the world as all the sound we make must create a sort of harmonic vibration. I actually hear it wherever I go and continue to search for peace and quiet. Having come across this site though I’ll endeavour to track it a little more scientifically.

  11. Lori says:

    I have been hearing the hum consistently. It began to pick up with the start of the new year 2021. It fluctuates in intensity. It is deeper in tone than previous years. Right now it’s quiet, but there have been a few nights in January where it was loud with a good deal of vibration. I will try to document the dates and times it increases.

  12. m says:

    Just started here in McKinney TX. 75071 … at first it was sporadic and annoying. Now I just feel crazy, can’t concentrate when I am indoors, the minute I go outside it is less, it almost feels like pressure and I feel the vibration behind the ears and behind eyes more than it is a sound. It causes tension in the shoulders, scalp and traps. Earl plugs and expensive sound canceling headphones do not work. Some moments it is deeper and more pervasive through the body and skull. It feels like it is bouncing off of the walls inside, outside it is just a steady mild (engine Idling) sound.

  13. Lori, m –

    It is helpful if you report the pitch you match to and some details of the results of using my checklist.

      Hello Bernie,

      Thank you for emailing me. I hope the information I am providing is beneficial. Regards, Lori


      1. Definitely not a truck. The loud muffler sound of a passing vehicle will actually block the sound of the hum for a few seconds.

      2. Only two other people have heard the sound in/around my home in the last 5 years. A teenage electricians assistant and the acoustical engineer I was working with to find the source.

      3. Does not block. Noise cancelling equipment failed, fans helped, sometimes the combination of a fan and tv worked. Classical music provided the most amount of relief.

      4. Not sure.

      5. In the past, it has been between 30hz to 50hz. Higher pitch in 2016, where it became unbearable and I had to leave my home. Right now it’s approximately 40hz. It’s a deeper and softer tone than it has been in the past. Since January 2021, I think it has been a fairly steady 40hz, with occasional increases in volume that make it uncomfortable. For example, yesterday, Tuesday February 2, 2021, it increased in volume at approximately 4:30pm. At some point it tapered off because it got my attention again at 7:15pm and was lower in volume until 10pm when it became more prominent. So I would say it has been continually humming at approximately 40hz, with sudden increases in loudness/volume.

      Unfortunately, the http for the electronotes I chose to listen to were not operational. So I could not compare the sound bytes to what I am experiencing. I did hear the tone clearly in the background music on Vanessa Lowe’s “Can you hear that?”

      6. It’s always there. When the volume is low, I can successfully ignore it.

      7. Yes it definitely surges.

      8. I did not hear it when visiting NY in January, June or December 2020. If it was present, it did not assert itself. But I did hear it in 2020 in Berks County, PA where I live, and in several neighboring towns and townships in PA.

      One last comment. I thought of this when I listened to Vanessa Lowe’s audio. Glen mentioned medications as a possible source of internal disturbance. I just verified it through my notes, and it seems I took doxycycline hyclate in 2015, and I had intercranial pressure from the drug. It took months to get over the side effects. I first heard the hum in 2016. I do not know how this compares to Glen’s research.

    Been hearing the hum in my home since 5 May 2020 in Nottingham, UK. Constant low frequency vibrating noise not blocked by earplugs. Sounds like a distant generator. Convinced it’s environmental as I have stayed in hotels/Airbnb since it started and it hasn’t followed me. Unfortunately can’t afford to keep paying for rooms so decided to try staying with relatives in same city occasionally to escape noise but I can also hear it in their home (9 miles from my home). However the hum in my relative’s home is intermittent so is slightly more tolerable than my home where it’s constant. This continuing experience is significantly affecting my health, i.e. severe sleep deprivation.

  15. Michael Kalinowski says:

    I have been hearing something for over 2 years. I am 59 and live west of the island of Montreal. I have walked and driven all over my neighborhood looking for the source. I can’t tell what direction it is coming from….I arrived at my cottage today which is 100 miles away and I hear it….sometimes I feel like I am on the verge of losing my mind..

  16. Daniel says:

    Louder hum for the last few days May15-21st which is today, quite oppressive. Anyone notice that or lots of irritable non-hearers. I’m in the gulf islands in Canada. Hum headed since May 5/20.
