Can you located it -- it's coming from the ground? air? direction?
Wikipedia says that it is in fact Zug Island: https://en.wikipedia.org/wiki/Zug_Island#Noise_and_vibration

You live there? What are the leading theories of what it could be? The article didn't seem to lock in on anything.
I live there ... I was away for many years and saw a few stories in the news and kinda laughed it off ... now not laughing so much The leading theories are it has something to do with this mordor like place https://en.wikipedia.org/wiki/Zug_Island
In a place like that, there would likely be multiple sources. Such as the three blast furnaces there. Which are among the largest in the world. They blow lots of hot air through lots of extremely hot iron ore, coke and limestone.
Also, does the hum change pitch a lot? With multiple sources at different frequencies, there would likely be beat frequencies. Which could be in constant flux.

#43Sigh. I've coded too much this week. My brain just immediately went to: comment out half the city at a time and binary search the source. Guess you can't really do that. I wonder if the hum persists during a power outage.
A few samples of amplitude should be able to triangulate it no?
Re: There's a Persistent Hum in Windsor, Ontario, and No One Knows Why
#44Three people so far have suggested in the comments here it should be "easy" to triangulate it. Note that according to Zug Island's Wikipedia page, "As of April 2013, a Canadian scientist is using sound-level meters and a portable "pentangular array" of cameras and microphones to try to precisely identify the source of the sound, in order to know whom exactly to ask to fix it" and that "the City Council had already sp…
What I don't understand is if they are just trying to locate sound source or looking for other waves, such as electromagnetic ones. When I walk under high voltage trellises I always hear my head humming.
Re: There's a Persistent Hum in Windsor, Ontario, and No One Knows Why
#45It seems like a sensor array across the city of just a few sensors could help detect the source. Using microsecond differences in the arrival of the sound, you could at least tell what direction it is coming from.
Sometimes it's not that easy. Imagine a swimming pool right after a lot of people got out. Where are the waves coming from?
The pool.
And yeah, we're vastly over simplifying. Imagine all the reflections and refractions that an urban center would introduce.

Replace "comment out" by "turn off the electricity for" and maybe we can binary search it.

You'd have to be able to synchronize the phase of your sensors. If it's a low 30hz hum with very little differentiation between individual cycles you might not have an easy way to do that. You could possibly build a big array with microphones at Also the sound could be reflecting downward from cloud/temp layers, greatly complicating it.
Not to say it's not possible, just super tricky.

At that point the city should just organize a contest and give 1 million to whoever finds it. For that much money I'm convinced someone will.
