Negative Feedback Training
I was next door to a second-story apartment full of kooks who were in some kind of cult "church" - opening all their windows and screaming prayers all hours of the day and night including hollering in tongues, to the point where people walking by would stop and stare up at their windows in amazement. All kinds of door slamming, tromping up and down stairs, stomping on the floors, banging against the common wall between our apartments at night after I wanted to be asleep.
So I got some free sound effect files from the internet (bangs, slams, thumps, thunder, etc). Made an audio cd that would play the sound files every 30-90 minutes for about 8 hours. Played it all night long every night over a subwoofer placed against the common wall of our apartments, which happened to be their bedroom wall - while I slept in the furthest room away wearing ear plugs.
Couple of months later they all moved out, will never know if it had anything to do with my negative feedback training. But I like to think it did. I don't think this would work if they live over you, but it seemed to work when they lived next door.
