…interesting.

So, looking at technical solutions, one thought is using active noise cancelling. Basically, use a microphone (or several) to cause destructive interference of the sound and reduce the amplitude in your home. While this would not solve the issue for others, it would potentially help you.

I could see it being done using a measurement or other high quality calibrated microphone (miniDSP umik as an example) hooked up to a raspberry pi, which then outputs sound to another amp and some full range speakers. It may help with the more annoying sounds, but is unlikely to drown out lower frequencies and resonances in the building proper.

While I’m not an audio engineer (just an amateur speaker builder and audiophile) I am quite curious to see if there is a solution.

That was what I was thinking about too. Unfortunately, I think since the noise is coming from a point source and the entire room has to be denoised, it is difficult. I doubt there would be a speaker configuration that perfectly destructively interferes with anything like that, unless you got a row of speakers (and there wouldn't be software for that either).

(I'm no expert in this though, so am probably wrong)

Question: Wouldn't create that noise for others, while cancelling most of the noise for you? The sound waves you create for cancelling cancels sound at one point, but keeps moving and creates noise beyond that. Isn't it?
