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.
I once had to tell the Indian couple above me to turn down their insanely loud Bollywood movie fest. When they came to the door the wave of noise that came out was like standing next to a speaker at a Motorhead show. I don’t know how they could stand it. They did turn it down finally.
This is the same couple who, based on the noise, sounded like they would take all of their pots out of the cabinets every night and drop them on the floor followed by a bag of marbles. Every, damn, night.
