soundproofing for good sound in basement

[commode air]

looking for options as to what the best procedure is for getting the best sound in basement. I have a concrete slab wall with ceiling height of 8'. I plan on insulating and sheetrocking. I heard there is a special sheetrock that has a purpose for sound. Have any of you heard of such a thing and does it work? Also I plan on having a suspended ceiling, is there a special type of ceiling tiles that reduce noise. My room will be for a home theatre. The dimensions are 25' by 15'. What else am I missing? Thanks for the info much appreciated. John

I need to sound proof a room too, however, I think I have to confirm to different REGS.

I guess what I really want to do is not so much sound proof, but to get the best possible sound in my basement. Having a concrete floor can make things sound a little different. Granted I'm going to put carpet over the concrete. Is there any specific types of paint that absorbs sound, specific carpet? Thanks for the input

I don't think there are any paints that make a difference, and a thick pad with carpet will help reflections off of your floor, but you still have 4 walls and a ceiling to deal with. You'll most likely need to look at acoustical panels at some point. If you are really serious, I'd get your room looked at by a professional before construction and then after construction for a post-build calibration. Then you can do whatever acoustical treatments you need without needlessly throwing money into panels. Every room is different, and you can't apply generalities to acoustical treatments. It seems like a lot of money up front, but they can also help you source your materials and save you a buck there too.

It was popular for a time just to treat everything below seated ear level with absorption, but that can get pricey and can be counter-effective to what you want to get done.
