How do you stop bass noise from neighbors coming through wall?

Answer 1

Short of building a recording studio-like room, there is not much you can do to stop bass frequencies from coming through a wall, as the low-end vibrations are particularly hard to silence. An extra layer of drywall hung on special sound isolation channel might help, but then there are the windows and the floor to deal with, and by the time they are dealt with the whole sound-proofing project can become very expensive. It may be better to go over to the neighbor's house and simply ask them to turn down the volume. Of course, another option is to turn up the volume on your stereo, but that would not be neither polite nor neighborly.
