Ideas on sound proofing
I built a TV into a wall in a bedroom. The problem is I can faintly hear the TV through the wall into the stairway. I have 1.5 inches behind the TV to play with and want to put some kind of sound proofing in there. The only thing I have found so far is at the big box store. It's a 1" thick sound board. Will this work or does anyone know of something better?
