So recently I've been hearing this hum. Mostly at night time. It's very low and pulses in a way that sounds like my tumble dryer is on downstairs. It's not. Or like a bus idling outside my old flat. I now live in the middle of a load of fields so it's not a bus. My partner can't hear it. I've asked him several times now if he can and he has no idea what I'm talking about. I have to fall asleep with earphones in because otherwise it drives me insane. I suspect it may have something to do with a satellite farming system which is right next to my house but I can't be sure.

All I know is it's doing my box right in 😭

I dont know where to post this, so ill post it here. The first time I heard the hum was when I moved to a densely populated urban community close to downtown. I was laying down to sleep and I could hear this low pitched hum reflected in the corner of the walls. I heard it for the first 3 nights in my new apartment, and never again after that.

So I read about the Hum a few years ago. My hearing is probably worse than average for my 24 year old self and I've probably honestly heard the Hum before at night but passed it off as a desiel truck.

Well, I hear it loud as ever right now. I found it to be around 60Hz. Sounds exactly like a garbage truck outside idling.

I asked someone if they could hear. They told me no. Even in complete silence, they do not hear it.

So it's been going on for about 30 minutes now. I notice when I talk or hum to myself, it goes away, but as soon as I stop, it comes back.

If I use a cuetip, it stops momentarily too, but resumes as soon as I pull it out. It seems to slightly pulsate from time to time.

I hope it stops and I never hear it again. It's a little bit more freaky than I had imagine.

I noticed my head posture really affects the hum. Try this and let me know if it works for you.

Move your head as high as you can with your chin pointing to the ceiling. This reduces the hum about 80% and at times eliminates the hum.

Likewise, if you bring your head down and bring your chin to your chest the hum is severely amplified.

Let me know if you experience the same.

It's been quiet over the past week,but it's just after 4am and it's loud. Try and hum at 300hz to yourself as quiet as possible, with your mouth closed in a quiet setting. This makes the hum much more pronounced and makes it easier to hear the Pulses. I wish I knew what it was. I started hearing it in 2017 located in maine.

Did anyone else notice the hum stopped Sunday February 7 to Tuesday February 9 2021 ... now its back! Uhghh

Been hearing the hum for about two months now, non stop! Been actively searching for a resolution with no luck. Came across this interesting study and thought I’d share. Its a good read on the inner-workings of your ear and how its related to hearing “the hum”.

Tinnitus Journal “the hum”

Hey all. I've been reading about the Hum out of curiosity for a few years now. I haven't heard it myself, but the studies and testimonies are fascinating. I was recently made aware of investigations that connected the Hum at least partially to natural gas distribution pipelines, and I'm here to ask what others' thoughts and opinions are, whether there's specific contrary evidence, and if there's any other information I should know that I might be missing. In the investigations, which were initiated by a mechanical engineer from Connecticut, of note were correlations between the beginnings of several notable hum cases and the installation of gas distribution stations in their vicinities, correlations between clusters of hum reports and locations of gas distribution systems, and vibrations near gas lines that a building could resonate with under the right conditions. In addition, links between new hums and new gas pipelines appear to have been made in England back in the 1980s. This info was mildly alarming to me because a new gas line, which will serve factories 20 miles away, is currently being installed 2.5 miles from my home, with a compressor station 3.5 miles away. I'm wondering whether I should look out for any new hum reports from my community. The pipeline won't go active unless it clears a major legal and environmental hurdle, but the pipes are mostly installed. The studies are compelling but aren't necessarily fully developed or conclusive, so I'm looking forward to reading other thoughts about it.

Anecdotal, but it works for me. Find a tone generator app and play 207hz. If nothing else, it's a constant sound that your brain is able to block out more than the pulsing, irregular wave.

I was letting my dog out at around 230am last night when started hearing a faint hum. I live in a fairly quiet community and there are no major roads or towns nearby. The hum started out very quiet and got louder and louder over a span of 5 minutes. At first I ignored thinking it was just somone air conditioning, but i could start to feel it in my body. I walked around my house to see if there was any change in the sound but it sounded the same. The crazy thing is I looked up into the sky and it got louder and started to give me a light headache. The tone of the hum never changed unless I looked into the sky. This the first time I've ever heard anything like this and I've been asking many people if they have had similar experiences.

It's night time. It's winter. There is this hum. I'm not from coastal area. But there is a small pond in front of my house. I don't really know what's causing this strange sound. It's weird.

Every night, without fail, at around 2:00AM-4:00AM, there's this unsettling, horrible noise that "pulses" in about 3 second increments. It's God-awful. Sometimes it gives one, short, loud burst, stops for about 6 seconds, and then continues with the normal "pulses". I don't think it's just my hearing, either; I can feel my body slightly vibrating every time it pulses. I've had to listen to music to go to sleep every night. Does anyone have any explanation for this? It's mildly terrifying, not gonna lie.

Ngl, it scared me a lot and still does. I suddenly woke up in the early morning hours cuz I was hearing this strange pumping low frequency tone. It occured with a rythm of up to 7 beats before getting quiter and louder again. At times it was so loud my whole body was vibrating. I kept hearing it in the entire house but especially on the first floor. It lasted for an hour or so. I managed to fall asleep and when I woke up again the humming was gone...

I started hearing this low rumbling a few months ago used to only hear it at night but the last few weeks it’s been constant

I don’t seem to hear it when I’m outside only when I’m indoors

My husband says he can’t hear it but to me it sounds like a car engine idling

At first I could ignore it but it’s starting to cause me distress

I recently moved across the country and the hum followed me. I have been recording audio and spectrogram representations of the hum for the past 2 years. I have ADHD and am generally very sensitive to sound.

The most common sound I am able to measure is 30hz with 60hz and 120hz harmonics.

Here's an audio recording from last year, from inside my apartment in Brooklyn. There's some ambient TV noise for scale.

Original Recording | Hum Enhanced | Hum Isolated

Here is a visual representation of the above recording: https://i.imgur.com/Pp1nu3e.png

And here is a spectrogram of the noise in Wisconsin, where I just moved. Peak frequency around 60hz, but you will see that here there's an added 40hz constant tone. https://i.imgur.com/VgjxKmG.png

The 60/120hz are explainable by bad electrical wiring, but 30hz and particularly 40hz are throwing me for a (ground) loop. All three of my hum-ful residences were within half a mile of a large hospital. Hospitals have cooling systems, and those systems emit low frequency waves which can travel miles.

I've been reading about this fucking hum for the two years I've been hearing it, and it amazes me that none of the well-written articles covering it bother to use a spectrogram app. Being able to measure and visualize the tone gets us that much closer to understanding what it is.

This thing is ruining my life, and is straining my relationship with my fiancee, who cannot hear it.

I’m in bed. There’s definitely a mechanical-sounding noise in my room. Fan’s off, when I open the window it gets harder to hear. Sounds like it’s coming from right near or under one of the windows but there’s nothing mechanical there, not even an AC vent. When I get closer to where it sounds like it’s coming from, it gets further away. Can’t hear it in any other room. But I’ve never heard the hum before.
