Hi Dan, I am a day behind emails and so you may have answers already.
Personally I will not hang dry wall but on 16 inch centers. Dry wall has too much give for a 24 inch center. The taping and plastering will be difficult as the drywall will give and sway. At the my office we put in a recording studio. The wall were simply 2x4. We filled the cavities with insulation. It worked very well. I do understand your desire to dampen sound. Personally I would make a 2x4 ajoining wall, 16 inch centers and insulate. My experience is that is enough. Dave A.

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.
