Q: I’m installing double drywall in the studio I am building in my basement, but how do I seal the gaps around outlets, the corners, etc.?
A: You definitely want to seal the room as much as possible. The more airtight it is, the more sound transmission will be reduced. The ideal is to use an acoustical sealant, which is like caulk, but stays pliable and flexible rather than hardening. A good choice is Auralex StopGap, which is designed for exactly this purpose.
