The acoustic dry wall is a good shout, but I don’t think my boyfriend would take too kindly to me shrinking our room and the shared wall has closets for both bedrooms. I’m hoping those closets will do something to help, and the foam wall paneling is a good shout, but I’m trying to think of ways to do it in a way that’ll please his aesthetic desires. He doesn’t want it to look like a “streamer’s bedroom”. I joke with him and say change one letter and it’s more accurate, so maybe he’ll considered some colored ones mounted at angles to create a more visually appealing surface. That, or try to mount a rug on the wall 😅
