Title SOUND-ABSORBING BODY AND SOUND INSULATION WALL EQUIPPED WITH SAME meetings achieved
Abstract

Provided are: a sound-absorbing body, in which the sound-absorbing effect is improved, the number of components can be reduced and the size can be reduced

and a sound insulation wall equipped with the sound-absorbing body. The sound-absorbing body comprises: a plate member (1) which has stiffness to such an extent that difference in sound pressure is generated between the front side and the back side of a part adjacent to the edge of the plate member to impart a pressure gradient

and a sound-absorbing material (2) which is arranged adjacent to the edge of the plate member for the purpose of consuming the velocity energy of air particles accelerated by the pressure gradient.
