Right, but you’re forgetting siding --> air gap—>sheetwood----> studbay with foam or glass----> drywall. Thats 4 layers of material to absob soundwaves and displace them. So again it just is a silly joke, its older than you are, find some better material. As i originally stated saying that makes you sound like an ignorant asshole. We also will do offset studbays to increase the material and differentiate the sound path. The engineering is cool. If you’d stop acting like a smart ass you might find it interesting.
