Sorry my bad.
One of the contractor's advised against this design and recommend a "HAT clip system" using 5/8" drywall. Is this a good method to achieve good sound, of course there will be GIK treatments used as well. Per this contractor the main concern is the type of door.Most important is to limit sound transfer from the basement to the up stairs,
So what is the accepted build standard that allows for good sound, without going overboard. Thanks for any input.
I will be finishing my basement and will have about a 16'X20' dedicated room. I confused on the best approach to frame this room. I have read here and well as other sites that double dry wall with staggered studs and green glue is the way to go.

Per this contractor the main concern is the type of door.Most important is to limit sound transfer from the basement to the up stairs, but the fact is anything will be better than the cramped spare bedroom I'm using now. So what is the accepted build standard that allows for good sound, without going overboard. My room I started with the same issues as you face. I spaced the studs on 16" centers so as to be to code. With the living room directly above I had to minimize sound transfer. Being as I listen to music at a fairly loud level I really was concerned. The most important thing was to keep sound out of the living room. I put three layers on the ceiling. First was drywall then I ran resilient channel with drywall attached to it. Finally I put acoustic tile on that second layer of drywall. My room is live end dead end with bass traps. It's very quiet in here. Acoustics are excellent. I have had a good share of "Wows". The sound making it to the living room can still be a bit much if you're trying to watch tv. The bass goes through to the living room close to full force. I can turn up my stereo but not as much as I'd like sometimes unless nobody is up there.This is an older house with real wood 2x4's that are full size and much heavier than today's woods used for building houses. My point is it's the mass that is key here. I'd be wary of listening to a builder as what they are used to isn't as severe of a problem as we likely deal with. If you can afford using lead that will help immensely. Just thought I'd let you know what my experience is. My system has very large full range speakers as well as a sub for the very bottom. If you don't listen very loudly say peaks to 80db max you will be fine. If I had it to do again I'd add another layer sheet rock. Btw acoustic treatment is mandatory for the best sound. I will argue that it can make speakers sound better than going to significantly more expensive speakers. Good luck
Bringing back the thread after being dormant for awhile! The build is almost complete, drywall and ceiling is now finished, the room is a nice size 20 ft X 14 ft. The non foundation walls have R-13 insulation with staggered stud. The ceiling is R-19 insulation, it was suppose to be R-30 but the depth of the joist was not deep enough for insulation that thick. Even at this stage the room is quite, don't hear anything from the floor above. Hope to move in by mid November. Tim
