When a Loud Sleeper sleeps in a room with a Pneumatic Door, the noise gets out of the room, but the same does not happen with Airlock. This makes building bedrooms pointless, as the Pneumatic Doors no longer isolate noise.
Steps to Reproduce
Have a Loud Sleeper duplicant, build a room with a Pneumatic Door and observe the noise from the sleep escape through the door to the outside of the room.
