i want to soundproof my bedroom as much as reasonably possible.
i was thinking of installing a solid core door and sealing all the gaps around it with weather stripping or something, but then i would have an airflow problem.
i have one air supply vent in the room, and currently the only way for air to leave is through the gaps around my door to eventually reach the return register. the pressure is so great that it will literally suck the door closed when it's a few inches ajar, so i worry that with the door closed (which is 24/7) i am maybe putting excessive stress on my HVAC system (which runs the fan 24/7).
so i was thinking, just install a transfer grill above the door, but i'm worried that will just bring back the sound issue.
how does one properly accomplish this goal? am i on the right track?

Vent through the attic or floor and connect it to the return duct.

i'm in a condo, nothing above or below belongs to me. connecting directly to the return isn't feasible.

I don't know how effective they are but my work was suggested vents with soundproofing for the offices.

Floor to ceiling curtains, acoustic foam panels, hang shit like flags or curtain pieces or something from the ceiling, build an angled wall to scramble the soundwaves (look up recording studio floorplans and designs), add extra insulation to the ceiling, rubber mats/pads under all your furniture feet. Alternatively you could stfu.

the only way to soundproof a room is to tear it down to the studs and adhere vinyl to every square inch. acoustic foam is not sound proofing. weather striping is not sound proofing. you can do certain things to mitigate small amounts of sound, but to truly sound proof something there is no other way than vinyl.

ok but there are still a lot of ways to improve sound mitigation, like surely if you replace a hollow door with a solid core door and seal all the edges, significantly less sound will travel through the doorway when closed.

OP building a rape dungeon and you’re all helping him.

>transfer grill above the door
why that and not something in the floor? like a linear shower drain but with felt?

I'm glad to do it.

It will go through the flimsy walls instead

Why does your bedroom need to be soundproof?

>>2930661 (OP)
Are you trying to block outside noise from getting in, or block inside noise from getting out? Those two situations have different methods and suggestions.

If you just want to drown out outside noise cheaply and quickly, just use white noise inside your room. It will block everything out that isn't in a bass register. Block insider noise from escaping requires adding a lot of insulation and damping mass is much more difficult to accomplish.

i want to insulate sound in both directions. i believe the bedroom should be a quiet, private place. adding white noise machines is not really the solution i'm looking for.
right now my doors are hollow and have gaps on all four sides, i think this makes the doorways the main problem, and it should be very easy to enormously improve them by installing solid doors and reasonably sealing the gaps.
i'm not talking about filling all the walls with insulation and vinyl mass, just what i feel should be some very basic first steps.
my only concern with this approach is that i believe i'll create an air pressure problem, hence the need for a transfer grill.
