I spent last summer working on a basement studio (installing a new ceiling of layers of think drywall on hat channel, making bass traps, and other treatment.) The space is now a quiet place to practice and record but it is too dead for my liking. As a cellist, I love playing and recording in concert halls I realize that it is a very small space (24'x17' w 7' ceilings - the short ceiling probably the worst for room sound?) but I would like to add some 'room sound' back if possible. I built a 4'x4' diffuser, totally unscientifically, random depths, but it seems to have added a bit of life to the space. I am thinking of making more of these and maybe having the back wall mostly covered by diffuser. I realize that there is a way to test the room and design diffusion tuned to the space but that is beyond my ability. Does anyone with more experience think that more of my randomly designed boxes would yield more liveliness to the sound of the room?
