Thank you to Henrik for his careful filtering of the raw data, and to Jason Lewis for his programming assistance on this one.

We’ve added just over 600 high quality data points to the World Hum Map. I’ve enlisted the help of a SFU Psychology student in generating the new statistics for Hum Hearers, and one early result is that we know the mean and median ages of Hearers are 43 and 45 respectively. I’ll release the full set of statistics when they are ready.

    600 data points? Hot spots of the hum? Without a doubt we hear the sound of emg. I have dozens of times cleared it from my head. As your one writer said its frequency has increased to a broader range. The person recording it. I thought it might be a single source. Please release the info on the 600 data points when you can.

  2. Bob widget says:

    Sorry. I’m only on my phone so can’t download the data. In a nutshell what does 600 data points mean? I checked your map but it has me confused.

    • There are now over 3600 closely vetted points/locations on the World Hum Map. Henrik used a very strict set of criteria and distilled an original set of over 14,000 points down to our current data set. It serves as a resource for professional and amateur researchers who want to conduct research on the World Hum.

    Not sure if this means anything or not. I was recently diagnosed with 2 auto immune diseases. All hell broke loose June 1st. Doctor put me on 50 mg of prednisone. While I was on the high dosage I did not hear or feel The Hum. Now that I am tapering off the prednisone off I do (now at 9 mg per day and should be off totally in 4 months time). The diseases generally affect older people in early 70’s. I am 66 and considered on the young side. Prednisone and Methotrexate are anti inflammatories. Since The Hum and Polymalygia and Giant Cell Arteritis affect mostly older people do you think that inflammation could be the reason people hear The Hum? Just a thought.

  4. Visitor says:

    I’m just wondering what’s the purpose behind this. The source seems undefinable even in where you lived for decades. Does it really matter that how many places got the sound? I mean we don’t even sure if the sounds are the same. Most Importantly, we can’t track the sources.

    I’m not a scientist but maybe we are receiving something from space (even without the aluminum foil hat!)

    Astronomers may have detected background ripples in spacetime itself (newatlas.com)

    I have been hearing this hum for almost 4 years now its at night. I have to play white noise on my cell phone to get rid of this very ignoring sound.
    I live in pa

  7. Visitor says:

    I’m not wasting time on the things that won’t go to anywhere.
    The fact is you didn’t track a single sound. You don’t know anything that caused the sound. Not even on the place you’re familiar with the whole life.
    Just drop it. It’s useless.

  8. Daniel says:

    Hum seems stronger to me the last 3-4 days May 16ish to May21st, anyone else experiencing this? Also more irritability in everyone around me. Just curious.

  9. Val Cross, Bristol UK says:

    I hear a range of low frequency sounds since around 3 years ago, but really intensely since August 2020. It had gone on 2 occasions for a long period of time. Once 5 Feb 2021 for 3 months, and second time from 2 June until 21 June 2021. Did you come across someone having it gone for such a long time before? Do you experience it yourself?I tried to get hold of you via email, Glen. We have a massive issue with this here in Britain. I live in Bristol, UK. I’m finishing writing a letter to our Prime Minister Boris Johnson for help. I and other fellow sufferers tried everything, as a mean of elimination. I would love to get in touch with you, please.

  10. David Hawkins says:

    I live in Nottingham in the UK and have been hearing the hum for about 10 years. For me it has 2 frequencies, both are low with 1 only slightly higher than the other. I hear the higher for a few seconds then it drops to the lower for a few seconds the time duration is random for both from maybe 5 to 30 seconds. It is at a low level or volume so is only apparent when it is very quiet for example when lying in bed at night. During the covid 19 lockdowns I have heard it a lot less often probably on 10 or 12 nights. I have thought it might be due to a lot fewer aircraft flying at these times. There is normally a lot of air traffic over England. I’m sorry I have never kept a log or diary of my experiences of the hum so it’s all from memory. Do you think it would be useful and does anyone else hear 2 distinct frequencies.

    • Diaries are always useful here, because they can be used as a tool for eliminating possible anthropogenic sources of noise. Cheers, Glen.

    • David –

      Did you pitch match the tones?

      Is the tone unterruoted about 1/2 second by a vigorous head shake?

      I gather it is far from 24/7/365 ?

      Thanks Bernie

      • David Hawkins says:

        Hi Bernie
        I haven’t pitched the tones and the hum goes from high to low without interruption, there is no head shake or any physical symptoms. Recently I have only heard it once on the night of July 26.

    • Harry Verey says:

      I hear exactly the same as you the higher frequency lasting 5-30 seconds it is very pronounced in the quiet of the night. The higher frequency is bothersome, almost slightly dizzying and glad that it is not constant as is the lower frequency. It was about ten years ago I first picked up on the Hum and have since moved house three times in my locality but the hum remains the same. Sometimes the hum disappears for a few weeks only to return.

    My constant low frequency hum ( often 2 toned at night ) has been for the last 2.5 years. I’ve written long descriptions of it to Glen early on, from May of 2019. Our power company ( Dominion in Virginia, USA ) is about to make some changes to the pole, transformer and underground power line, and a new meter ( not a smart meter at my request ). I am hopeful that something about this will change the hum that has made us want to move. We do not want to sell our home. Wish us luck. I will let you know if the hum ceases after this project!

      I just laughed at myself! I read your post and I scolded the screen, “Well, DID it!? People never come back later to post what happened!” Then I noticed you posted YESTERDAY! lol Anyway, please do come back and tell us if the hum you hear ceases after your project.
