I'm going into one of the worst audio environments imaginable. A large, spacious room with hard walls, a hard ceiling, and a hardwood floor. I plan to get a large area rug to cover as much of the floor as possible, but I'm not sure how to deal with it otherwise. What are some cheap ways to treat the walls and ceiling to deaden the room a bit? I'm looking to spend around $200, so acoustic paneling is basically out of the question here. Is there anything I can do with my furniture, like put bookshelves in the corners, that would help? What I'm going to have includes a bed, dresser, 2 bookshelves, a beat up old couch, a few cheap chairs, a computer desk, a big old multipurpose table, and the HT furniture. College student style in its truest.
