We recently had carbon fiber strips applied to a basement wall to keep it from moving any further (it was bowing inward about an inch with a horizontal crack). The company that did the repair had to remove the drywall from top to bottom in two separate sections of the finished part of the basement. The width of drywall removed is between two studs for both sections (the other carbon fiber strips were applied in an unfinished portion of the basement). I've seen how to repair large sections of drywall by screwing in overlapping pieces of plywood on the backside of the drywall) but the drywall was removed flush with the stud. Suggestions on how to repair would be most helpful.

I live in a two floor coop. I'm on the second floor. I snore. When I snore my neighbor knocks on the wall and wakes me up to 5 times a night. His bedroom is right below mine. I've tried putting 4 layers of carpeting on the floor. I even got carpeting on one of my walls that I stapled into the wall. Nothing has worked so far. I actually don't even snore that loud according to people I've roomed with and I don't have sleep apnea. There is so much information online about soundproofing I don't know what to believe and what not to. Can anyone give me some advice on how to soundproof my room so my neighbor doesn't hear my snoring and lets me sleep?
