How to Soundproof a Return Air Transfer Grill (Above Door Air Vent)

If you’re in the process of soundproofing a room, you might be in a little pickle if you have to deal with an above door air pathway transfer grill, most commonly referred to as an overhead door air vent or some call it a return air transfer grill.

"An air transfer grille provides an opening from the bedroom to the hallway for air to return back to the air conditioning air handler or furnace when the supply register (vent) in the ceiling of the bedroom is blowing conditioned air into the room.

If it wasn’t there and the bedroom door was closed, the only way for air to return to the air handler would be through the narrow undercut slot below the door. The door undercut does not provide a sufficient opening, so the room would become somewhat pressurized and would not receive as much conditioned air as rooms that had an open return air flow."

You can completely block the vent off, but then you’re left with a room that lacks the proper amount of return air coming in from the hallway or the adjacent room.

Your next option is to try to reduce the noise coming from an overhead door air vent. This Video will show you just that, with a couple options as to how to soundproof an above door air vent.

The First option is to install a Noise Reducing Hunnycomb Insert from Tamarack Technologies.
