無響室用の段階吸音層の構造である。[Detailed Description of the Invention] Conventionally, sound-absorbing wedges are used for the interior of anechoic chambers, but this invention uses a wedge-shaped sound-absorbing body formed by molding a wedge-shaped frame, covered with cloth and filled with sound-absorbing material. Since there is a frame, sound waves are reflected, and the frame has the disadvantage that it is expensive to manufacture and is not easy to install.This invention has many irregularities formed by cutting sound absorbing plates into various sizes and stacking them on different levels. Since it is a sound absorbing material and does not use metal, there is no sound wave interference and there is a large sound absorption area, and it has the characteristics that installation work is easy, and removal and individual replacement are easy. A sound absorbing board (1) made of soft sound absorbing material is cut into A, B, C, and D, and a sound absorbing body (3) is formed in different layers for each thickness of the sound absorbing board, and a protective cloth (2 ) (or mesh cloth) can be used to temporarily insert an additional board (4) to increase the sound absorption area within the anechoic area, allowing the room to be made wider than with conventional sound absorption wedges. This is an ideal structure of a staged sound absorption layer for an anechoic chamber that is lightweight, easy to handle, and inexpensive.
