Acoustic treatment for a garage ceiling


I'm helping a friend convert his garage to a HT. He's going to put up studs, add insulation, and sheetrock the walls (cinder block construction) but he doesn't want to put in a suspended ceiling. He'll run cables in conduit, hang track lighting, etc. and paint the ceiling flat black. His question: Are spray-on acoustic treatments effective? If so, which work best? Can he apply them or must it be done by a contractor?

Any and all advice for taming a highly reflective ceiling will be most appreciated.

Have the ceiling sprayed with cellulose insulation fiber. This will deaden slap-echo & will also help insulate against heat gain/loss & attenuate outside noises from getting in. You'll often see gray cellulose fiber sprayed on warehouse ceilings & walls; usually several inches thick. It is also available in bleached white, which is what I had applied on my listening room ceiling with excellent acoustic results. See an insulation contractor for details & ask about mixing in some black paint or dye with the glue before they apply it. Be aware that this is a messy job so mask accordingly.
