Howdy. I am going to start construction in a couple of months on my new house. My media room (interior dimensions) are 19' (front/back) and 16'11" (sides) with a base ceiling height of 9' (the plate height of the house). I know that these room dimensions are not optimized golden-rule-wise, but there are still a few items I can play with. 1) should I step the ceiling up to 10' (this would require soffits - a box ceiling if you will - since the front wall is an outside wall, and other posts have indicated that soffits add a lot of unwanted reverberation and reflections). I'm trying to make the room sound as good as possible, bearing in mind that the other dimensions cannot be changed, and I'm curious if a 10' boxed ceiling would sound better than a 9' standard ceiling with the other room dimensions taken into account. 2) I am trying to figure out to what extent I should soundproof the room on a tight budget, since I like to play movies loud (who in their right mind doesn't?). One of the side walls has the kitchen and dining room on the other side of it, with the family room on the other side of the kitchen/dining room (all other sides of the room aren't adjacent to areas where I'm concerned with noise transmission). My current plan has an offset 2x6 wall (see this diagram) between the media room and the kitchen/dining room, with the other walls being standard 2x4 construction(see this diagram). On all walls and the ceiling, I am planning on using a single layer of sheetrock/gypsum board, with ASC's WallDamp between the sheetrock and the studs on the interior of the media room (all 4 walls plus the ceiling) as well as on both sides of the wall that is shared between the media room and the kitchen/dining room. The shared 2x6 wall will also have QuietZone wall batts in it, and I plan to treat all the joints/cracks with acoustic sealant. I have calculated that the cost of the walldamp and the sealant is about $1200 extra. Is this going to sufficiently mute the low frequencies so that I don't wake up my wife? :-D Would adding an additional layer of sheetrock (like this) make that much difference? 3) Do putting sound batts in the walls make the room itself sound any better, or do I just need those in the walls that I am concerned about sound transmitting through? I suppose the same question applies for the WallDamp. Any insights would be GREATLY appreciated.
