ANECHOIC CHAMBER AND FLOOR UNIT THEREOF

摘要

PROBLEM TO BE SOLVED: To switch the floor surface structure easily in a short time and to eliminate the space for containing a radio wave absorber on the outside of an anechoic chamber. SOLUTION: A plurality of floor surface structures 5, each comprising a metal plate 7 bonded to one side of a support 6 and a floor radio wave absorber 8 bonded to the other side thereof, are laid side by side on a floor part. Each floor surface structure 5 is made reversible such that any one of the surface of the metal plate 7 or the floor radio wave absorber 8 faces the ceiling part selectively and the metal plates 7 of adjacent floor surface structures 5 are made to be interconnected electrically.
