The Controversial Sound Only 2% Of People Hear (Benn Jordan, YouTube/Piped/Invidious, 32m38s): Since the early 1960's, an increasing number of people have been hearing (and feeling) a sound causing everything from annoyance to psychosis to death. We have a deeply objective look at what could be causing it.

The TL;DR of the video is that it (a creepy low humming noise, heard by 1 out of 50 people) is definitely no one single thing, and may just be in the heads of the hearers, but - and this is important - it doesn't make it any less real, since sound as we perceive it is a mental process that is just interpreting the real world in a specific way.

For those who don't believe the YouTube to right-wing pipeline is real - the next video this wants to show me (logged in on my work Google account where I never use YouTube) is Lex Friedman (the bad one) interviewing Tucker Carlson. :-(

I found the pipeline explanation a little chilling (err...I'm talking about the gas pipelines in the video, not the youtube fascist pipeline jferg points out above) because these things are EVERYWHERE. While I don't seem to have this hum in our area, I'm really sympathetic because our house basically acts as an amphitheater for road noise--my office in particular--and the extremely low, skull-shaking hum does make you feel a little crazy after a while, especially if you step outside and can't hear anything.

You can use the AI summarizer Summarize.tech to produce a summary of the video.

The summary of the whole thing includes this:
The video presents theories regarding ELF waves, military communication systems, wind turbines, and hydroelectric dams, among others. Despite extensive research, the origins of The Hum remain largely unexplained, leading to questions about mass hysteria, tinnitus, or mental health as potential causes.
It also summarizes each 5 minute chunk.

(A lot of Youtube videos have transcripts these days, but I couldn't find one on this video.)

Is the sound at the beginning of the video a legit sample of the actual sound or an artists rendition?

Also, why did he say "listen to this" and then give us a third of a second before the music starts?

I remain skeptical that this is anything other than normal ambient noise. 1 in 50 is not very many, and I've known at least one person who was middle aged when they noticed that they could hear themselves swallow.

I'm confused. I'm on the autism spectrum & like many on the spectrum, I have hyper-acute hearing that can make ambient noises sound louder to me than for a neurotypical person, but it's just something I recognize and mentally tune out. I don't necessarily experience it as this ominous hum following me around. Is this like that? Or is this supposed to be different?

From what I understood from the video, this is different. This would be a low-pitched, rumbling ambient sound that is not associated with, say, the high pitches offered by electronics or fluorescent bulbs; or plumbing; or the internal sounds of tinnitus, ear-drum pressure shifts and wiggles, vertebral artery noise, or heartbeats; or the thing some sounds do where the brain picks up voices in random noise; or any one of the million other little noises that absolutely plague you if you can't stop noticing them. It should be low enough that you feel it as much as hear it, depending on how loud it is.

I think they're referring to flexing the muscles that open your eustachian tubes to equalize pressure around your eardrum. When I do that, it trembles and I hear a low-pitched rumbling sound.

Not only am I surprised that not everyone can rumble their ear drums, I am also surprised that it seems to take some of you specific tricks to do it. I can do it easily without any visible movement of my face. Internally, it feels a bit like I just 'blinked' my ears.

"Blinking my ears" now, super easy, can do the left, then the right or both at the same time. After blinking, sound is clearer. I never thought about it. It's an internal muscle flex (I guess) and I don't think it causes any external visible motion.

The sound in the video? Is this a joke that I'm not getting. It was extremely loud and very noticeable. Mostly in my right ear. We're supposed to be able to hear it surely. This is a bit right?

I think that might be different? I can do a quick "blink" (sounds internally like a crinkle, or crunch) without any visible action, but the sustained, ongoing "rumble" is a different sound that requires me to close my eyes, and some strain/tension that's probably visible (but I can't see, because my eyes are closed)

Yes, it's not so much can you hear this--in terms of your ability to hear--but do you hear this--that is, is this sound out there in your environment driving you crazy, whether it's from pipelines, wind turbines, weird infrasonic mating calls or what have you.
posted by mittens at 1:37 PM on March 5 [1 favorite]


I just will my ears to rumble and they do with no other activity involved.

The process is not really distinguishable from willing a hand to raise — with the exception that it's hard to will my ears to rumble individually: I can make my right ear rumble a tiny bit on its own while the left is silent but not the other way around. I can only rumble continuously for about 40 seconds or so, though, and after that I have to relax the effort and start again, but can only manage short burst of a few seconds until my ears recover in some way.


There were four hypothesized causative factors that really stood out to me:

1. The ibuprofen connection.

2. The gas pipeline and other infrastructure connection.

3. The autism and ADHD connection.

4. The fact that “fully ambidextrous" people are overepresesented among hum hearers by a factor of 5 or 6.

To me, that all adds up to a conclusion that the sound is real, but when 'immunotypical' individuals experience it, their immune systems soon come along and edit out their ability to perceive it, very similar to the way that many people can hear the 15 kHz flyback transformer whine as children but have lost the ability by the time they reach adulthood with the exception, among others, of asthmatics, who retain the ability much more often than the general population.

This may be less " editing out ability" than plain old hearing degradation that typically comes with age. That's the case with me, someone who's lost significant hf hearing as the decades have passed.

I also did not know until recently that the voluntary control is relatively unusual. I'm like jamjam - I just... tell the muscles in my ears to tense up, and they do and I get the rumbling. It's sometimes nice to be able to close your ears the way you can your eyes.

Ha! I learned how do this accidentally, when I was 8 or 9 years old. I really wanted to figure out how to wiggle my ears, and I spent several afternoons in the bathroom, staring at myself in a mirror while I tried to work out how to get my ears to wiggle. That was the first time I heard the "rumble", but I didn't think much about it (I just wanted to wiggle my ears).

Now I'm an old, and after seeing all these comments about ear rumbling, I realized that I too can voluntarily flex my tensor tympani. I can do it without visible signs, but only for about half a second. I can't really get it to go longer than that, though.

I learned how to wiggle my ears by paying attention to what happened when I was scared or startled. I could feel my ears perk up, physically. And so I tried my best to isolate that sensation until I identified the muscles, and from then on wiggling my ears was really easy.

Before that it was me standing in front of my mom, not doing anything, and asking her if I was flapping my ears like Dumbo.

Well I have never heard of rumbling your eardrums. Fascinating. I can pop them, but...

I also have major hearing loss in one ear, but lately, when I cover my good ear up to try to sleep, (too noisy otherwise), I am essentially hearing radio baseball play-by-play. Even though I can't tell what is being said. But the same cadence, crowd response, mumble mumble. Very odd.

ah yes, The Hum.

When I was living in Seattle, I started hearing a Hum. My partner couldn't hear it, but I could. It started abruptly one day. This deep, insistent noise down at the bottom of my hearing range. And it was loud. I could feel the pressure of it. Everywhere I went in the neighborhood I lived, it was there. Go elsewhere in town and it was gone. Leave town and it didn't follow me.

I had trouble sleeping because it was so damn loud. I'd put in earplugs and they'd cut it some but I could still hear it. I started sleeping in different rooms in my apartment because it was slightly less loud.

I still started gaslighting myself, wondering if it was all in my head. Wondering if it was a symptom of anything. This shit really fucks with you.

It was still going when I left Seattle in 2019. I wonder if I'd hear it if I went back to visit? In the unlikely event that I end up there again I'll have to go make sure down to the University District at night and find out.

Thanks for reminding me that's not in my life any more. I'm really thankful it's gone. And kind of heartened to know that apparently about 1/50 of the rest of the neighborhood was also silently sharing my misery.

My hum's beginning coincided with the end of the work on the new transit tunnel for the neighborhood. For a while I suspected something from that as a source. I dunno what the fuck it was. It sure wasn't tinnitus though. Not with it being out of my life ever since the moment I moved out of there.

I sure wondered if it was tinnitus. That's part of what was driving me crazy. I could see it driving me to suicide if I stayed. Not that the grey winters weren't doing that already, but the Hum sure wasn't helping.

It's a shame the well's been poisoned with paranormal/conspiracy crap when it comes to the mysterious hum(s). My feeling is that one of the worst aspects of hearing a persistent hum may be the inability to explain what it is. I can see how it might drive some people batty. And I think that might be compounded when those persons have been primed to think there's something paranormal or conspiratorial. And made worse when nobody else can hear it (or cares to try hearing it). I suspect under similar circumstances, the issue might take me to some dark places.

I've been absolutely amazed at how well sound/vibration can carry and be heard. That seems like a weird thing to say, but over the last 20 or so years, the longest I've lived anywhere, in my house, I've been able to notice how remarkable it can be to notice low level, and absolutely mundane, sounds travel. And sometimes only be heard under odd circumstances. I've never dedicated much time to figuring out why I sometimes can hear distant sounds that can't be heard as easily when closer to the actual source. But it seems resonating surfaces/cavities can be remarkable amplifiers under the right circumstances.

Actual hum, though, isn't present at my house. I do sense hum/vibration two places: both while parked in a non-running car, at my place of employment, and also at my wife's place of employment. For a while, I thought it was something in the car that was still running, even though nothing was running. Then I noticed it in a different car. I have a general sense of what may be happening, but I'm not that motivated to find out or let it get to me.

Perhaps living in a fairly noisy city, between I-10 and an airport, keeps me from obsessing over ambient noise in general. Every few months, I take a trip out to a very remote spot in the desert for the night, to enjoy the stars and nighttime sounds. When the wind dies down, it gets deathly quiet, and if I lived in such a place with a persistent, unidentifiable hum, it would probably affect me much differently than the traffic and aircraft always surrounds me, where I live.

I've heard the hum since 2020. I appreciate this post a lot. And I'm really glad the video takes a rational, scientific approach, because there's a lot of nonsense conspiracism around this phenomenon on the internet. I've read Glen MacPherson's writing on the topic (he's interviewed in the linked video) and I've put an entry into his Hum Database. My experience of the hum is exactly as he describes it: a very low frequency that I hear and feel. It is mostly drowned out by ambient noise during the day, but sometimes in the stillness of night it seems so loud. Playing a tone generator alongside what I'm hearing, I've measured it at 75 Hz (going up or down by 1 Hz gives me 1 Hz beats), though it may be 1/2 or 1/4th of that. It certainly feels lower than 75 Hz. It really annoyed me when I first started hearing it, but now I'm sort of used to it.

At first, I must have seemed a bit mad to my wife. I was doing things like walking around the house in the dark, listening keenly, with the power to the house shut off. I have lots of speculation: Is it vibration from nearby interstate 90? Is it the throb of ship engines at the Port of Seattle? Why does it seem louder in cold, clear weather? Is it entirely in my head? Why don't I hear it while sitting in my car in the driveway? Etc.

Back for more. Yes "blinking" my ears makes a crinkle noise. But when falling asleep at night, I can totally hear a rumbling if I'm even the slightest bit tense around my jaw/ears/side of my head... There is a low rumbling. I notice it, relax, and it stops.

Okay onto the hum - there's a big honking iron ball in the middle of the Earth that is spinning very, very quickly. I have finished the video yet, nor am I smart enough to understand the scale of masses we're dealing with. But is it possible our spinning iron core is causing extremely long wave subsonic vibrations?

Jane the Brown, the title of this FPP is a reference to the song "For What It's Worth" by Buffalo Springfield, which is about the paranoia and conspiracy-theory mindset of the 1960s. The chorus is "It's time we stop / Hey, what's that sound? / Everybody look what's going down." I think it's a very clever title for a MetaFilter FPP that humorously situates the content into context in at least two different ways (the textual level of being about a mysterious sound, and the contextual level of being about conspiracy thinking), and is the sort of thing I particularly enjoy seeing here. Personally, I don't think it's clickbaity at all. Tastes and perceptions may differ.

Huh, that kind of describes what I've been hearing for years. It's a bit like the hum of the ST:TNG Enterprise, but louder and a bit louder in my left ear.

I had assumed it was some weird form of tinnitus, something produced by the inner or middle ear itself. Or maybe my faulty auditory nerves. In my case, I don't think it's an outside sound as I have moderate hearing loss, and don't really pick up on such things.

I don't know if it's the same thing, but my wife and I both experienced a sound that would pass through our room at night, usually around the time we were going to sleep. Which sounds like it might be caused by a dreamstate or something, but again my wife and I both heard it at the same time. A low hum sound would start on one end of our apartment and move through the room, east to west I believe, and move on west, fading out eventually. It was very deep and I felt it almost like a vibration. Very strange. This happened maybe a dozen times at the most over a few years' timespan, the last happening maybe 2019 or so? Haven't heard it in years now, but it was genuinely strange, and I have no possible explanation for what it was.

I lived about a hundred feet from a fairly large gas pipeline for half a decade and didn't notice a thing. Of course, I'm really good at tuning out noises, but even when it was super quiet out and I was standing on top of the right of way I heard/felt nothing.

When I say good at tuning out noises, I mean after the first month living next to a freight line I'd hardly notice the trains going by despite it literally shaking the house.

The closest thing I've heard to the Hum was the sound that signaled the arrival of minor earthquakes in Oklahoma. That was more like a rumble to my mind, but also in that weird place between hearing and feeling. Moments later, at least in the particularly large (for Oklahoma, we're talking magnitude 4 here) ones, there would be a little bit of ground motion that could be felt, but beforehand it was just the not-quite-a-sound. Sometimes that's all there was.

I feel for anyone who has to hear a sound they just can't escape, no matter what the source. On the bad days, tinnitus can really drive me batty. Thankfully, those are pretty rare for me. A long "attack" for me is a couple of hours before it fades into the background. Only a few times has it gone on continuously for days. Well, after the death of CRTs anyway.

As much as I loved screens back in the day, there were many occasions where I wasn't consciously hearing the noise or the feeling of pressure from that goddamned whine until I finally turned off all the TVs and monitors in the house and felt the sweet relief. It felt like my head had stopped being crushed, but I didn't notice that it was being crushed in the first place.

If you are hearing a hum and are not sure if it is real, download any of the many sound spectrogram apps for your phone and play with it.

There is this new high pitched noise that goes on for days at a time here. The spectrogram shows a very bright line centered at 3.5 kilohertz and about 2 kilohertz wide. This looks just like the the Steam Deck fan hum that was controversial some time ago, but is too loud to be it.

The low end of my spectrogram is red hot from the nearby highway.

I have yet to give a serious try to locating the origin, but waking around and giving the app 20 seconds to sample ambient noise I know that the hum is loudest to the north of my house.

I wasn't consciously hearing the noise or the feeling of pressure from that goddamned whine until I finally turned off all the TVs and monitors in the house and felt the sweet relief. It felt like my head had stopped being crushed, but I didn't notice that it was being crushed in the first place.

Persistent noise is like that. The bathroom exhaust fan is one that reliably does it for me, but it's really surprising just how pleasantly shocking a sudden silence can be, and in how many circumstances that's noticeable both in literal and metaphorical senses once primed to look for it.

The few times I've heard The Hum have involved lying on my back in deserts in the Pilbara while staring straight up at the stars. Both times, it got louder when I rested the back of my head on the comfy cobble put there for that purpose.

I do recall wondering about the source of it at the time, but not seriously; it seemed only natural that lying on my back in the dead quiet of the desert night would give me the opportunity to perceive all kinds of stuff that usually hides below all kinds of noise floor. But now I'm wondering how close I actually was to a gas pipeline, of which the region has several.

Finding out that gas pipelines can do that is kind of hilarious to me. I can just picture the glee of the first fossil fuel PR flack to realize just how effective it would be to pin all the blame on wind turbines.

I heard this when I lived in rural Oregon, nothing around to explain it. I even turned off the main breaker to make sure it wasn't something electric in the house. It drove me absolutely nuts. I especially heard it when laying down to sleep, which is the worst time to hear it. It was like there was so little background noise to drown it out so it was so clear to me. My husband thought I was imagining things.

I've heard it other places too, but nowhere as strong as those four years in the Oregon Coast Range.

Turns out you can hear a steel rolling mill from a surprisingly long distance at night.

It's amazing how different sound can be depending on environmental factors. Wind, inversion layers, seasons changing the amount of foliage, etc. There are some train tracks not particularly close to where I live, and 99 percent of the time I don't hear a thing, but on certain evenings I will hear the horn as clear as a bell. Or planes going over -- usually the traffic in and out of San Jose airport doesn't cause any issues, even though I can see the planes, but occasionally it must bounce off an atmosphere layer, because then it will be thunderous.

Correction: 20 hertz wide, not 2 kilohertz.

Now I just went and set up 3 microphones on the roof to see if I can do any triangulation with non calibrated mics and a continuous tone.

So... I have this. It's been going on for about 5 years.

I first noticed a low hum at night, usually around 11pm-5am, when the world outside was quiet. For a long time I thought it was something in our house. But then I could hear it outside, but not all nights. Other people on Nextdoor said they heard it. We even almost started a nighttime detective hum-finder team.

We moved to the country where it is dead quiet. And I still hear it there!

Ultimately, what I figure out is that the sound is coming... dun dun dun... from INSIDE MY HEAD. Since I only hear it in one ear, and it stays in the ear if I turn my head, I think it's clear that it's just some sort of rare low frequency tinnitus.

When I say good at tuning out noises, I mean after the first month living next to a freight line I'd hardly notice the trains going by despite it literally shaking the house.

When I was in college, there was a set of four apartments within spitting distance of a train track (almost literally). We had some study groups there and I was amazed when the residents would just stop talking when a train went by and start right back up as soon as it was quiet(er).

Then, I moved into the apartment the next year. Like you, it was maybe a month before I didn't notice the train. I also didn't notice that I, too, had formed the habit of not talking when train nearby. It just... happened!

I can voluntarily 'rumble' my ears, since I was a teenager - I've always thought of it as a "click" - others can hear it when I do it - it's great when you go underwater, or are on a plane, you can equalise the pressure in my ears, I'm told frequent scuba divers try to learn how to do it.

It has nothing to do with my tinnitus, as an electronic engineer, I always assumed I was just hearing the noise that's in any circuit, until it suddenly got louder last year ....

Hey all you eardrum rumblers, you have voluntary control of your tensor tympani muscle. Just thought you should know.

Like other ear rumblers, I just thought everyone could do this. Now, I have a name for it. Cool!

If anyone was following, I managed to locate the hum to an empty house two doors down, which is interesting since the house has not had power or water for about 6 weeks. Got the neighborhood association involved and they contacted the owner, who sent someone to investigate.

It was the low battery alarm for a large UPS. The hum is gone. I can finally rest to the soothing sound of distant 18 wheeler air brakes and dogs howling in the neighborhood.
