We’ve tried the usual of calling police (three times), inviting them over to hear how loud it is (they agreed that it was very loud), asking to at least reduce the bass, blasting our own music (not sustainable) and so on. Sometimes it works for a day but inevitably it’s back to the usual.
Hoping for some petty revenge ideas to complement the other efforts.
Research frequency that literally makes people feel ill, nausea… set up. Wear ear plugs and leave for a while.
No idea if this has ever worked.
I’m a sound engineer and I had awful neighbors. So I tried that to calm the monster of a kid my upstairs neighbors failed to raise.
I tried every pure frequencies from 12 000 kHz to 20 000 kHz with 1000 Hz steps at absurdly loud volumes.
The problem here was the air in our different apartments acting as an isolant, the material between our apartments, and the fact that this kid and his parents where deaf fucking morons.
In the end, the proper solution was to move. That worked as intended as I don’t hear them anymore.
I’m sure this idea was very impractical.
