Quiet Solution's Soundproof Drywall adds damping features to standard drywall tiles for near perfect soundproofing.QuietRock from Quiet Solution is a soundproof drywall: it hangs and finishes like standard drywall, but its layers of internal damping — a patent is pending — provide the sort of soundproofing you would get with eight layers of regular drywall, even if you hang items on it. Pricing starts at $39.95 for a 4' x 8' panel in 2008.
