I would recommend something a little different. It's called a "chicago ceiling", and uses WHR blocks that suspend a ceiling that is then sheetrocked. You need the sheetrock to keep the sound in and controlled. As has been previously mentioned suspended ceilings won't do this. In fact, they stop very little transmitted sound and usually make the room sound terrible. The WHR block is a spring loaded suspension ceiling. This give virtually complete isolation to the floor above. Not only will you hear very little from the audio room, you will very little in the way of footsteps from above.
Sound control when finnishing a basement?
I am about to finish the basement in our home which will become my new audio/video area and want to know how best to control the sound going through the ceiling. Some of the ceilung will be dry walled but most of it will be a drop ceiling with tiles. Are there tiles that you can use in a drop ceiling that will control sound better than the typical tiles that you can buy at Home Depot?
