After doing a 2x4 drop on the bar area of my open media room to clear all the pipes running in there, I put up a sample piece of drywall and I hate it. The ceiling would only be 6'-9" and It feels soooo low. So I've decided to do the industrial look and just paint all of the joists and subfloor/vents/pipes etc. Now, how can I somehow control some of the sound? Could I do Dbl layer of rock btw joists with green glue? Would I hear a difference?
