There is a simple answer. Black Diamond Racing Pits (carbon fibre material $60 each). Will make speakers sound better anyway and with deal with the floor movement.
floor vibrates like a speaker
Hello,
I am close to finishing my listening room. The walls and ceilings are two layers of sheetrock hung on resilient channel. The problem is the floor. My room is over the garage. The sub floor is 1" t/g particle board. It resonates like a speaker into the garage below, and although it loses some db, it makes its way through the garage walls to the neighbors. I intend to insulate between the floor joists but I doubt if that alone will add much to the STC value. I have seen lots of recommendations for sound blocking, including using expensive vinyl pads. However, the least expensive and one of the more common mehtods recommended is adding a layer of sheetrock (or 2) over the subfloor and then a layer of plywood and then put your carpet pad and carpet. I wonder how soundboard in place of the sheetrock would change the dynamics? Your input is as always, welcome.
