Soundproofing???????????

what if i hang a rug on the wall???

When I lived in an apartment I had the same problem so I got some blue hard foam insulation (it was 2 inches thick and 4x8 ft sheets)and made a wall. I covered both sides with quilting material and then covered the side facing into the room with a very dense material from the cheap bin at the local fabric store. The new wall fit snuggly in place with about a two inch air pocket between it and the original wall. It held in place because I made sure the side walls and ceiling made a snug fit. It blocked out most of the sound going through that wall. Another thing I did was decouple the speakers from the floor using cork material plus a hockey puck as feet under the speakers. I was able to crank up the volume and never had a complaint in the two years I lived there. It was relitively cheap on the front end and the new tenent liked it so much she paid me exactly what it cost me.

It takes a little time to measure it and put everthing together but remember it's all for the joy of listening and enjoying the music.

hi bruno, where do i find 2" thick 4x8 blue foam? do you have to screw the 4x8 into the wall??

I think its real nice of you to soundproof your room so others won't hear your music. I too set up a noise barrier wall to block outside noise from coming in. I'm sure it will block inside noise from travelling out and disturbing your neighbours. Its worth the money and really good looking too.
