Hey,
I was just wondering what’s the best way to soundproof a ceiling with vents and cold air returns..!? Should I build a false ceiling..? And run 2x in between the joists so the sound vibrations don’t run through and up the joist or what should I do here man!? Haha! Thanks!

To sound proof Dad's addition in Sutton QUE. we used metal "Z" strips as strapping, thus it issolates the sheet rock from the ceiling joists.
Thanks man!
Do you know how well this worked or how well it or many STC's (Sound Transmission Class) it reduced it by...?
Sorry, no clue as to the rating but I'll tell you, I sure can't hear the kids in the living room when DW and I are trying to sleep in and let the grandparents hold the fort. The bedroom is right above the living room. And before you ask. NO, With the parents right next door in the other bedroom? not!!!!
Would need more sound proofing than that!!!!!
Wrangler,
So are the return ducts just lying on the drywall ceiling? If the ductwork is sized right, you would never know its there. If its lying on the the drywall, suspend it and wrap it. Put some batts between the duct(s) and the drywall. If the return grille is whistling, get a bigger one or put a volume damper in the branch, close to the air handler and slow down the air a little.
Sound proofing for other reasons, can be done in a few different ways. In the hotels I've worked on they designed wall with staggered 2x6 studs on 2x8 or 2x10 plates. Some use resilient channels on 90 degrees to the studs/joists and attach 2 layers of drywall on that. Some fill the cavities with a sound deadening foam. Some use combinations .
