I'm in a basement of a strip mall. The ceiling height is 9 feet. Above me are various business's. The one which is most problematic is a hair salon. Boy can I hear the click and clack of those ladies heels as well as the snappy dialog going on up there. The ceiling is most likely 1/2" sheet rock. I've got a control room, tracking room, and an iso room. What would be the best way to minimize the sound leaking down as well as drums, bass, and guitars bleeding up?
