Soundproofing a shared at a duplex
Hey Everyone, We built a duplex and are having issues with the shared wall not being soundproof. We have MLV, quietrock and of course type x drywall(2 sheets sandwiched on both sides)total of 4 sheets of fire x and 1 sheet of quietrock. But our long term renter says they can hear everything. Any ideas on how to reduce sound?
