So I'm setting up my basement as my record player poker lounge. It's not a finished basement, so the hvac vents run along the ceiling, exposed, and transfer all the sound of me jamming out down there to every room in the house. Sound leaking into the first floor isn't such a big deal, but if SWMBO is on second floor sleeping, the vents carry that sound up to her room like a metal drum, and if there is one thing I know it is that I don't want angry wife yelling down the stairs for us to quiet down. Is there a product that I could wrap the exposed vents with that would minimize this issue? Or is that a lot of work without much effect? Or is finishing the ceiling and covering joists, vents and all the way to go?\n\nI've done searches for sound proofing AC vents, but most everything I can find is for recording studios to minimize sound of the ventilation system itself coming in to the recording studio. I'm just trying to prevent sound from my stereo and poker buddies from getting into the vents.
