So I'm in the process of building my theater room and it is directly below my master bedroom. I will have 11.2 surround sound with plans to add an infinite baffle in the future and in doing some preliminary sound tests, my wife has expressed her concerns about how much sound will transfer through the floor to the master bedroom. Granted, the ceiling is wide open right now so I'm not sure what it will sound like under normal conditions (with typical insulation and drywall)... Now most of the time I would expect her to be down in the theater with me watching movies but she is worried about the times she isn't. Two of my walls are exterior walls of the house so I did nothing special on those but I built a double wall on the side that connects to the rest of the basement (so I got drywall, studs w/ insulation, drywall, 1" air gap, studs w/ insulation, and drywall again). Then my other wall goes to my utility room so I will just have normal walls w/ drywall & insulation there. I will have insulation in the ceiling but wondering if I should add extra layer of drywall, sound board, green glue, some type of rubber layer, etc. Any recommendations on materials or methods to help with sound proofing the ceiling?
