Sound proofing question... - 09/11/06 04:20 PM
I am sure you guys know a thing or 2 about sound proofing but I really need some advise here.
I already put up the walls and painted them in my theatre room in the basement. I was planning on a drop ceiling which is why I already painted and such.
I have been researching and have found out that It would be more benefitial financially to just use Quietrock drywall on the roof with some high density fiberglass insulation above in the joists than to install acoustic ceiling pannels that have a decent STC rating (the best STC rating i could find for ceiling pannels were 27 whereas the lowest quietrock product has 52-70 STC).
My dillema is this; 3 of the 4 walls are backing onto the concrete foundation, so there is no sound transfer there. The 4th wall backs onto the opposite side stairs going upstairs which I failed to insulate and do any sort of sound proofing on.
Will it be benefitial to spend a little more money using quietrock drywall on the ceiling (5/8") at $50/sheet (i'll probably need 7 sheets for the ceiling) even though sound will still transfer through the wall backing onto the stairs upstairs? Or should I just use regular drywall on the ceiling because if one of the walls will transfer sound out then its kind of a weak link?
Some of you guys with dedicated rooms please chime in.
I still have access to the part of the wall backing onto the stairs and will stuff all kinds of fiberglass in there to prevent further transfer of sound.
