Earfull Junior Audioholic May 10, 2005 62 0 6 May 14, 2005 #1 For noise reduction to upstairs from a downstairs HT room, is there any noticable benefit/advantage in using 5/8" dryall on the ceiling as opposed to 1/2"? (The 10" joists will be insulated with pink fibreglass insulation). Last edited: May 14, 2005

Two layers of different thickness, or an acoustic board under drywall, or Z stips, or other damping isolators betweent he sheetrock and joists. Joist will transmit the sound just fine

Since the room is for sound you'll want to run the RC asymetrically a little bit to avoid the amount of resonances at the same frequencies. It helps alot. I ran soundboard then resilient channel to controlled density drywall covered by acoustic tile. Sound upstairs is now very little even with my system at a fairly loud level, peaks over 90db. I'm running a Parasound HCA 3500(350wpc) through a pair of Vmps RM 40's(260lbs ea. and 90db) and the females that live here say the little that comes through while they're watching tv doesn't bother them at all. The HT room is directly above the listening room.
