I have limited knowledge on room acoustic, hope someone can share his expertise with me. My listening area now has a suspended ceiling with plasterboard, distance between the plaster board and bare concrete ceiling is about 6inces. When I run a frequency sweep from 100Hz down, my ceiling board begin to have audible vibration at various location depending on the frequency, at about 60-80 Hz I can feel the bass gone louder and more vibration, kind of resonance I guess.
Some audiophiles friend advise me to use stronger suspension rod/board with rockwool filling in between. My personal thought favor a bare ceiling so nothing vibrate above my head. In the later stage I still have the option of adding diffusion panel or whatever if need to. This option save me downtime and cost, the only downside I can think off is appearance, which I don't really care that much.
What other disadvantage about bare concrete ceiling acoustic wise ?
