Abstract
A file cabinet is disclosed which has a door with high sound absorption properties. The door has metal front and rear panels and an intermediate layer of sound absorbing material sandwiched therebetween. An array of openings are cut through both the front and rear panel. Sound impinging on the front panel enters the cabinet via the door and is attenuated in the door and cabinet. Preferably, paper files are stored within the file cabinet with their peripheral edge surfaces disposed towards the rear panel to assist in attenuating sound within the cabinet.
