    ok so i keep hearing that in order to soundproof u have to build a room within a room and the gap between the two rooms is where u put the sound proofing material...so the only question is how big does the gap between the two rooms have to b??? can i just use a 2 x 4 and put a piece of dry wall on each side and insulate between the two pieces???

    Outside the room >> Drywall (2 layers of 1/2" would be nice) >> Insulated studs >> Air >> Insulated studs >> Drywall (2 layers of 1/2" would be nice again) >> Inside the room.

    Note no drywall in between - It's actually worse, as the sound will pass through the inside drywall easier than the air. Especially the low end (which is really what you're trying to stop anyway).

    Most places I've worked with have about 2" (well, 1-3/4") in between.

    The insulation goes into the studs, just like it would with any wall. 8# per cu.ft. rockwool would be my suggestion.
