You're on the right trail for sure. I have a couple of kids who are into music and I wanted to dampen the sound so I had a local drywall contractor come in and install some acoustic panels in my basement. It really is nothing more than cork boards to dampen the noise. I'd recommend you take a little time to design what you want, its not that difficult at all. Good luck!
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?
