what is good to use for home theater sound deadening?

My family is thinking about moving into a new house with an unfinised basement, but we plan on finishing it. We want to make it partially a home theater type room, with a nice sound system. What would be some good ideas for insulating the ceiling or something so the bass doesn’t rattle the whole house?

Room acoustics is a bit of a black art. You seal off the sheatrock to prevent high-frequency from leaking out. But you need WEIGHT to keep the bass in the room.

This can involve putting spacers and a second layer of sheetrock, Dow Corning has special fiberglass and special sheat rock for sound deadening, etc.

Saddly – I dont know of a good book to recommend. You may have to consult a acoustics expert on what to use.
