Inquiry (采购产品): Soundproofing / Noise Reduction I'm interested in finding out what materials you have and recommend for noise reduction for a small rehearsal/recording studio in a garage. Sound-deadening board has already been installed on top of sheetrock. What would be an effective material to go on top of that? Also interested in pricing (probably for 4x8 panels).
