my current neighbors are ridiculous, and I've made every effort to be good about noise as well. I've never played any music past 10, and when I do play tunes I keep them low volume, but they still complain. The other day I was bangin it out fairly loud at about 2:30 on a tuesday afternoon, and they start pounding on the wall! Well, they can get bent, **** that, I turned it up so I couldent hear the pounding. If it was 2:30am, then fine, call the cops if you want, but 2:30 in the afternoon, on a tuesday! I think they are of the opinion that music should never be played, ever.

Anyway, I've never got involved with the environmental health people, cause it takes alot to get them out, but if gets to that level you want to sort it out pronto, cause they'll install noise monitoring devices at your neighbors place, without telling you, and then if the levels coming from your place are too loud, you will get screwed over. Happened to some friends of mine.
