How does one eliminate the noise? One of those sensory deprivation chambers? Audio insulation?
Build and live in an anechoic chamber. Don't make it too good though or you'll go crazy. https://www.google.com/search?q=anechoic+chamber&tbm=isch

From the bottom of the document that you cite: > We note that the bearing from Array 1 to the most probable source of the Hum points well to the South of Zug Island. The bulk of our observations from both stations do not support the hypothesis that the source of the Hum emanates from Zug Island. Even if it is from Zug Island, "unknown origin" is still appropriate until they know WHAT is causing it.
They have it narrowed down to a few thousand feet. To call it "unknown" is just unfair. They might not know which steel plant is producing it, but they can narrow it down to a small handful, far from "unknown". They have enough evidence of which company is producing the sound (United States Steel), so the only thing stopping them from getting police or lawmakers involved is the fact that no one on the US side cares e…

I have been working on a project to use some DIY bone conduction "headphones" to do directed noise canceling because I'm on the autistic spectrum and loud places bug the shit out of me and make it so i can't focus. Bone conduction is neat because it works inside your head and doesn't cover your ears. I think BC noise canceling is really under explored for audio related stress issues. I'm putting a mic on the back of…
Could you link to the low frequency drivers? There's a bunch of stuff like that on adafruit and I wanna make something similar.

There is a wide range of transducers out there, if you start digging around the units can be hard to find. Sometimes they are called Exciters. This company PUI Audio makes a bunch.

The large transducers from Adafruit are such odd components. I haven't really found anything that will push that much power, but I think there are better packages for my application. They sound great with the recommended 20w amp.
Here is the STM32Discovery board I am using and the FFT libs.

It's constrained, but it's still unknown. It's not saying there is no clue about the origin, and narrowing it to a few thousand feet/a few possibilities still means the source is unknown.

That sounds like an awesome project
I've been told by a few people that bone conduction noise canceling is impossible, but I beg to differ. I did a patent search the other day and it looks like Apple filed a patent on some bone conduction noise canceling headset concepts that use accelerometers[1] and so did another company I've never heard of[2]. Also in 2002 the us government funded a $100,000 research grant for it[3]. I do a lot of AR/VR R&D, I have for about 10 years. I'm pretty convinced that selective sound isolation with bone conduction headsets is crucial to a good AR experience too but at the end of the day I'd just like to be able to go to a social gathering without a performance hangover or not want to kill my buddy because his jaw clicks when he eats.

Sorry for this I am not experiencing it so maybe I'm completely wrong but these people seem to be overblowing this a lot. Health effects? I mean, it's a hum. Sure you can't find the source but heaters hum, ACs hum, cars going past hum, bass hums. Like how is it possible that it's this huge of a problem? When a humming stops I tend to actually miss it because it becomes too quiet. I tend to hear the air conditioners o…
If it was louder, some may actually find it easier to ignore. I can sleep easily with either a quiet room or with a loud room fan on, but if there's just the fan noise from my NAS I find it much more difficult.

If I close my eyes, open my mouth and tilt my head back I can hear a hum. Is this The Hum?
This might be a case of https://www.reddit.com/r/earrumblersassemble/
Oh weird, I always assumed that was something that people could just do. It never occurred to me that there would be any particular variance in it. Oddly enough, it seems a little easier to do if I close my eyes.
As one who can hear these sounds, I can attest to how maddening it is. It's even worse when (most of) the people around you can't hear it, and they don't believe you. Earplugs only make it worse, because they filter out ambient noise that otherwise helps distract you from the incessant hum. Daytime is not as bad as night because of the natural activity sounds of a city. I have read that waves and underwater currents…
I was plagued by the Hum for years. At times it became astonishingly loud. But I was able (eventually) to figure it out. Short version: I made many attempts to track it down. Used low frequency Microphones, filters, amplifiers, etc, as well as PC Spectrogram programs to try and and visualise and record it. Visited many nearby industries etc to try and find it. But none of my attempts did any good. As I'm a Radio Engi…
Surely you asked other people if they also heard a hum? If they said no, what made you not focus on the ear right from the beginning?
