Will adding insulation to the basement ceiling help sound?
I will be drywalling my basement ceiling. Would using R13 unfaced insulation be helpful in controlling sound from the upstairs? The upstairs floors are wood so you can hear quite a bit through the floor to the basement. Would using the insulation be helpful or will it not matter even with the sheetrock?
The short answer is no. You would use decoupling clips, to hang OSB, then use Green Glue, then hang 5/8th's drywall.
Before all of that, you need to go through and get rid of any junction points that may be hidden when you hang the ceiling, proper lighting, sound proofing material around the light and outlet fixtures to stop sound transmission, etc..
