Abstract

음향실에서 음향을 감쇠시키기 위한 음향감쇠기가 제안된다. 본 발명에 따른 음향감쇠기(1)는 감쇠할 실내의 벽 또는 천정에 배치되는 프레임형상의 스페이서요소(2)와 스페이서요소(2)상에 배치되어 벽(6)과 함께 캐비티(5)를 둘러싸는 판흡수기(3)로 구성된다. 판 흡수기(3)에는 다공성흡수기(4)가 배치된다. 본 발명에 따른 음향감쇠기는 광대역범위의 주파수에 걸쳐서 음향을 감쇠시키며, 특히 풍동시스템에서 사용하기 위한 평면구조 때문에 적합하다.A sound attenuator for attenuating sound in an acoustic room is proposed. The acoustic attenuator 1 according to the present invention comprises a frame-shaped spacer element 2 arranged on a wall or ceiling of a room to be damped and a spacer element 2 arranged on the spacer element 2 to enclose the cavity 5 together with the wall 6 Is composed of a plate absorber (3). A porous absorber (4) is disposed in the plate absorber (3). The acoustic attenuator according to the present invention attenuates sound over a wide range of frequencies and is particularly suitable for planar structures for use in wind tunnel systems.
