I have a small one story condo with each unit separated by a concrete block
firewall with wall board on either side. Unfortunately, neighbor noise such
as loud talking, TV's and radios, comes through without much problem. To
give you an example, when reading in my living room next to the common wall,
I can here someone peeing in the bathroom on the other side.
Anyone have experience in this area? I've heard of sound dampening wall
board but how effective is it? Would some kind of spray foam against the
concrete block do the job?
