Soundproof a wall: Best (Level 3)
The Double Stud Wall with Green Glue is our highest performing wall assembly. Currently, most acoustical labs have a hard time plotting double-wall performance accurately, as the wall often exceeds the flanking limits of the lab.
A drawback of this solution is space efficiency. With it, you are basically building two walls, which requires a significant amount of space.
The Double Stud Wall Assembly
Double Stud framing is the most effective way to decouple a wall. Best at Low-Frequency isolation, the Double Stud wall also offers a structural wall to hang very heavy elements such as cabinets, equipment, speakers, etc.
