Also see what noise laws are and cut it off at 10PM.Tell him you here loud TV's and if you had known there was paper thin walls you wouldn't have bought but you did.Ask him his schedule because if he's not around and you are you can play and be adccomodating.Other wise go to tell him ( and woners association) that YOUR rights are being trampled on.A woman in an apt. long ago called for sirt time must have looked me up in the book we never met) anmd asked if I could remove my shoes when I came in.She obviously had nobody abover here for year or might have had somebody who weighed 120 lbs not 220.I did it for a weeek and then thought "this is BS" (I was new guy she was oldest etnanat etcaccording to lanloard etc).Botttom line SHE got used to it.Girlfreind moved in more niose and no problem.She worked second shift to I could crank my muisc up then but even after when at home I really had to have TV loud for her to complain.At fisrt just listening level was enough top call.:atter it had to REALLY be to loud.Hope your neighbor will make accomodation other wise call cops ask about nmoise laws and if need ne your assosciation (maybe a lawyer if they seem to back this guy entirely-you have some rights after all)in which it meakes it seem like YOUR trying to be acccomdating where as this guy wants a monastary.But folks get used to ambient noise they thought they wouldn't is what I found.
