@dang why did you delete the "And no one knows why" from the title? Did it sound clickbaity to you? Seems pretty critical to the article to me. The whole thing is about the search for what the hum is, not what the hum is.
(It's better to send questions like this to hn@ycombinator.com, as the site guidelines ask. When you post in the thread, we only see it by chance.)

> Meaning it's just a rendition of a hum, not an actual recording of "the hum". ...what? Did you not open the link at all? Or are you suggesting they're lying? They literally explicitly say it's an actual recording of the Windsor Hum at 11:12pm on August 24, 2011...
It sounds like any generic dubstep wubbler preset you can download. At least from the few seconds they played it without someone talking over it. Seeing the video does not make me less skeptical. I don't know that they're lying, but I do not have great faith in human perception.

Listen to the one linked in the article, not the one embedded in the article https://www.youtube.com/watch?v=tPDILKQjJW8

It's actually a not unpleasant brown noise-like sound. At least that's how it comes out of my hifi. Over bluetooth and after YouTube compression so perhaps high fidelity isn't the right term.
I'm not sure... for me the unfiltered version was annoying but bearable for a bit... but I could see getting driven mad by it after a while. The filtered version was so bad that it almost made me wonder if I'm going to damage my ears, so I stopped listening to it halfway. I was using decent BT headphones so I'm not sure if that makes any difference... it may depend on how decent your speakers are at playing 30-40 Hz.…

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/
Alternatively, it could be a resonance mode between infrasound stimuli and tension/relaxation of the tensor tympani. Eg. Pressure pulse -> TT reflex -> neural reflex drops as sound is blocked by TT -> repeat.
Total speculation, but this would explain the person-dependent experience, as well as the inefficacy of earplugs, sound dampening, etc.
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…

If I open the front window and back window in my car then drive at a specific speed I get a very weird woop-woop-woop and it feels like the air is pushing me back and forth in my seat. It pulses my head. Wonder if it is something similar.
My car does this too. No previous car I've owned has had the same issue. Hopefully it isn't inherent to modern automobile aerodynamics because I'd like my next car to be one without it.

I'm listening to this right now [1] and (for those of you who don't have a chance to hear it right now) it definitely isn't what I would call a "hum"... that's way too gentle and not bass enough to describe this sound. I'd call it more like low-frequency rumbling (though that's probably not a perfect word for it either). [1] https://www.youtube.com/watch?v=tPDILKQjJW8

I'm putting a mic on the back of my head to pull the room then stereo directional mics out front to actively noise cancel the room but not the person I'm looking at in a cone that I can fiddle with. Initial tests seem to work! I'm trying to improve it with a crossover for low frequency on the jaw just under my earlobes and a mid/high driver on my temple. I think even a commercial setup for bike riders and some experimentation you might be able to find some relief. I've found them to be lacking in lower frequency which is why I'm using stronger drivers and the below the ear positioning.
Might be something to try playing with. It's pretty inexpensive. I'm using "Surface Transducers" from Adafruit and an STM32F4 Discovery board to process the noise canceling (has great FFT libs). All in my current setup is maybe $150 with a couple iterations under my belt.

Exactly, BT audio uses lossy compression. There are several codecs available but I'm on Linux and the receiver is pretty old so it's probably the weakest of them: SBC. The filtered sound is pretty bad, yes, dread inducing.
Thanks! I had no idea.
