We recently replaced all the carpet in our home with hard floors, dramatically increasing the amount of noise transmission between bedrooms and the hallway. I've been researching the best ways to sound proof the doors, and I would like to seal the entire door, including the undercut at the bottom.
Regardless of what I end up using, I'm concerned this will impact the return air flow coming out of my bedrooms, as there is no other return. Is there a typical method for making up for this, while still also keeping sound transmission low? I've seen the return grills that attach to the door, but these aren't very aesthetically pleasing, plus I figured they would probably nullify the sound proofing I just performed. Is there another, not overly complicated way to have return air flow, maybe a vent above the top of the door?
