Over the past several months my upstairs neighbor has changed from being a noisy neighbor to a neighbor that could best be described as abusive.
His stereo and TV play at the highest volume almost 24/7. He doesn't seem to have a job and never leaves his apartment (Note: he's not elderly or disabled). It keeps me and my wife awake all night. I have tried to talk with him about this in person, but he will not answer the door. I have left him letters asking him to turn down the volume, especially late at night. However, I found the letters crumpled into a ball and left on my doorstep. I called the police; when they arrived at my apartment, they concurred that the situation is "serious." However, the neighbor would not open his door for the police, even after they repeatedly knocked for 20 minutes. The police finally told there is nothing they can do. In retaliation for the police knocking on his door, my neighbor flipped his speakers so that they play directly into his floor and through my ceiling, just above my bed.
I contacted my building management, who said they would send him a letter telling him to keep quiet. However, I can guarantee that this will not work; I doubt he will even read the letter.
There has been ongoing problems with this neighbor. Last march he ripped his radiator from his floor, causing a massive leak and three foot hole in my ceiling, just above an electrical outlet. However, he would not allow the plumber or super into his apartment to fix it, so the problem persisted for almost two months until the landlord got a court order for him to open the door.
I'm at my wit's end. I haven't slept in 24 hours since the noise is so bad. I bought a white noise machine, but even that won't mask the noise (it's that loud). Has anyone face a similar problem? How can I address this. So far, the police and the landlord have been of no help. And negotiating with this man person-to-person seems impossible.
