The plan is to join two adjacent rooms with an exhaust fan. One has air conditioner, the other does not. A handyman will drill a square hole into the wall, and then attach the fan. The goal is to cool both rooms when the air conditioner is open.
Since we live in an area where this setup is rare, we don't have any idea if noise will be an issue. The person in the other room plays music at night. If noise will be a factor, is there a method on how to minimize the sound? Will the addition of sliding/opening doors (like a wooden cabinet) solve this?
