My HT room in our new house has an existing drop ceiling. For budgetary reasons, I will be keeping it for now (as I have to pay for a new floor in the entire basement and I will be adding some soundproofing to the walls, as well as acoustic treatments to the room). I have two questions: Is a drop ceiling better than a drywall ceiling from an acoustic properities point of view? If I remove the panels to get at the joists above (probably a foot above, will know more in two weeks), would adding some sort of soundproofing/insulation/other?? material in-between the the joists accomplish anything even with the drop ceiling, or should I not bother. My goal is to reduce (I know I can't eliminate without serious money) sound transmission upstairs AND have a good room, acoustically speaking. I get the impression that the drop ceiling tiles will help with acoustics vs. drywall, but will be far less effective than drywall for sound proofing purposes. Is there anything I can do, or will the rest of the house have to put up with the cannons in Master and Commander?
