Many years ago, we needed a sound booth at the tv station, so we put doors on both ends of a short 8' hallway between video production and the newsroom. Then we covered everything but the floor & gear shelves with Sonotex. It looks like egg cartons, but molded from a memory compounded acoustic foam. Fairly expensive for a wall covering, but gave us an instant acoustically dead room. And it lowered the background noise level in the room from the air conditioning etc, at least 20db. It glues on to install, and would be hard to get rid of the glue when you leave, probably requiring new drywall to clean up right. Landlords might not be the least bit impressed, so clear it with them first. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
