5/Th's vs 1/2" sound reduction?
I'm in the process of finishing the basement. I figured on 5/Th's drywall on the ceilings. My question is how much greater is the sound deadening using 5/8 over 1/2"? I don't expect it to be dead silence, but I have a 15 year old and when this project is finished I expect her to have her friends over playing music, giggling and yelling etc. So I would like to reduce the volume when we are upstairs. I'm thinking of an insulation between the joist. I know there are great ways if money isn't an issue, but I'm looking to minimize sound some and maximize my dollars as well. Any ideas would be welcome. Thanks!

I've done a several of recording studios and condos for sound proofing.
Using resultant metal channel can reduce the sound by up to 80%.
As long as there is no height issues I'd go with resilient channel and 5/8" drywall. :thumbsup:
