photograph of anechoic sound chamber
Black and white photograph in a wood frame. It shows the interior of a rectangular room with all its walls, including the floor, densely covered by fiberglass wedges alternating in orientation between horizontal and vertical. The picture was taken from a bridge suspended by steel cables from the ceiling of the room, which supports a narrow railway track and enters the room at mid-height from floor to ceiling. The very thick entrance doors are open in this picture and a loaded railcart can be seen in the adjacent (normal) room on the tracks.
