When I build the wall separating my finished basement room from the shop, I am attempting some sound dampening strategies. From talking with a guy who built a studio in his basement, aside from making sure there are absolutely no air passages through the wall, the main consideration is mass-air-mass. Heavy walls, separated by an air gap.
I intend on using a 2X6 footer and header, with offset studs so there is no bridging between the two wall surfaces. My question is, do I put the studs for each wall surface 16 inches on center? Or can I put them 24 inches on center? The shop wall surface will be 3/4 inch plywood so that I can hang shelves on it. So, I think the plywood will be stiff enough to be supported on 24 inch centers. However, the finished room wall surface will be 5/8 dry wall. Is 24 inches on center enough support for the dry wall or does it need to be 16 inches on center? Thanks. -- Blue skies. Dan Rossi Carnegie Mellon University.
