None of these geniuses have figured out that the real problem is that when there are MULTIPLE wind mills running at similar frequencies and slightly different phases, an interference pattern is established by the multiple sound wave fields colliding with each other, resulting in a standing wave pattern in which several areas will have the low frequency sounds tremendously amplified. Standing at such a location one could be bombarded by a tremendous sound wave, whereas a few yards away could be dead silence.

Now assume one’s home sits right where one of those loud standing waves constantly hits and once can easily imagine the home essentially becomes a large low frequency drum. And the horrible thing about low frequencies is that they penetrate everything (including you) and there is no practical way to establish baffles or barriers.

Really, this basic high school (or first year college physics) regarding wave behavior. Or at least it was 45 years ago when I went to school. Who knows what (if anything) is taught in government schools these days.

(BTW, documenting the above phenomenon with actual measurements and the attendant mathematical models would make for a great PhD thesis.)

That makes sense, and it explains why not every one experiences this.

I’ve heard old timers talk about this effect when riding prop driven transport aircraft. When the pilots were trying to sync the props. They would hear the engines then for a few moments they would be perfectly synced and it would be deathly quiet.
