I'm looking to soundproof my apartment bedroom. The bedroom itself has a single-pane window, relative thick carpet, and a cheap hollow core door. It has no air vents, only a hot water baseboard heater.

I'm primarily concerned about sounds coming from within the unit. It seems that they transfer in primarily through the door. Long term I do want to do something about external sounds as well but I think my only option there is acoustic curtains (or whatever they're called)

I understand that I should be adding a door sweep, and acoustic tape to the door frame to form a seal. However, I'm wondering if there's any health risks associated with low oxygen because the only way for air to get in is around the door.

Are there risks? Should I form a close but not tight seal? Any other ideas?

I'm also considering add a hallway runner to the hallway, and some art there to break up the noise before it gets to my door.

    How big (in m3 not m2) is your bedroom?What I mean how much air is in there? Apr 6, 2015 at 7:11
  • I'd say 22.5 m3, roughly. The door will be closed for about eight hours a night (though obviously this could go on longer for whatever reason). Apr 6, 2015 at 17:45
  • Could you post this as the answer? The logical conclusion (after a quick google) is that I'd have to be in there for two days without opening the door before it becomes an issue. Based on 11,000 L air consumption per day (based on person at rest). Apr 6, 2015 at 17:54

How big (in m3 not m2) is your bedroom? What I mean how much air is in there? I’m not sure that there is a danger that you will run out of air? Although it is a good thing to have source of fresh air.
