We are putting a new addition on the house and I will be getting a semi dedicated theater room! It will still have weights/treadmill/elliptical in the back. The dimensions are roughly 23' x 24' minus a small furnace room and wall materials.
For sound insulation we were going to have two layers of drywall with green glue, but due to time, money and weight consideration we have changed course. The ceiling will be suspended on a track and the walls will have staggered studs. We are going to have insulation in the ceiling & walls as well as a layer of soundboard. It will be a forced air furnace and hope to have a dedicated line for this room.
Anyone with soundproofing experience, I appreciate your input. I know there is a sacrifice by not going the green glue route, but I have been told that decoupling the room is probably the most signifcant first step in noise reduction.
I am going to try to post a few pics taken from my iPhone using the panoramic feature. I promise the boards are straighter than that. :-) The bracing is also temporary until some materials are moved from the floor above.
