I have a room in my basement that I would like to use as a practice drum room. I am not going to use the room to record but just to practice. So, I would like to prevent the sound transmission from leaking outside of the room as much as I possibly can afford.
The room is 12'9" long by 7'8" wide and 6'11" high with a small closet (2'4" x 2'8") in the corner (I will post a layout of the room later). The walls are insulated and then sheetrock. I'd rather not knock down the walls if I don't have to, just so I can save money. I am going to carpet the floor and there will be things placed in the room such as speakers, a desk, a dehumidifier, and other things that might help reduce echo.
