@b_limo Appreciate your contribution. To have value the batts have to be cut just right to give a secure “press fit”. There will not be any need of support before adding drywall. Ensure the batts are slightly thicker than the studs. The you have the benefit of damping the drywall with the pressure of the batts. All this will pale in comparison to 5/8 Quietrock smply attached via green glue. No nails. If dabs of a different industrial glue are required for strength, use one that remains resilient. This type of adhesive is readily available.
What's the best way to soundproof a room on budget
I'm starting to research ways to reduce sound transmission through a wall since I'll be moving in a few months and my new living space will share one wall with another family. What I am thinking is nailing cork board onto the wall and then covering the cork board with inexpensive foam pyramids. I think I could do thewholewall (8-9 feet high? 14 feet wide) for around $500-$600 dollars going this route. Any suggestions for whats worked for you?
