Title:
SOUND-ABSORBING BODY AND SOUND INSULATION WALL EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/102278
Kind Code:
A1
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.
