This is the everlasting question it seems. I have started building out my basement and so far this is the plan. HT room approx 13x21' the room is in my Basement and I live in a Condo/Townhome environment. So keeping my sound in and the outside sound OUT is imperative. The front/back walls a cinder block - will be framing this out with 2x4's, insulation and probably a layer of Mass Load Vinyl. The left and right walls will both be leading to adjacent basement rooms - sound proofing is important here so it doesn't feed upstairs. I am looking at doing the Staggard stud with 3 1/2 insulation on both sides and 5/8" drywall on both sides. My big concern is teh Ceiling. I have 7'10" ceilings where the room is. Not to much to mess around with. I'm thinking of packing in more insulation, using the Mass loaded vinyl here as well as 5/8" wallboard Should i focus on using Resilient Channel here if my biggest concern is sound traveling up or are there some other secrets of the sound proofing a ceiling that i need to be aware of? My Hometheater is more of a home media room. Will be setup for PC/Movies/Xbox gaming and ofcourse movies. Designed around a 5.1 setup using Rocket speakers and around 200 watts of power. Is there an easier method such as using some accoustic tiles or something rather then hanging resilient channel on the ceiling? Want to control costs as the room is dual purpose. Decking it out for my theater to have environmental controls but i want to keep it good for dual purpose use so when it comes time to sell if somoene isn't an HT nut they can use the room to let there kids play drums, be loud or whatever Thanks!
