SOUND INSULATION WALL EQUIPPED WITH SOUND-ABSORBING BODY
흡음 효과를 높일 수 있으면서도, 부품 수의 삭감화 및 소형화를 실현할 수 있는 흡음체 및 이를 사용한 방음벽을 제공한다. 에지 부근의 표면 측과 이면 측에 의해 음압차를 발생시켜 압력 기울기를 부여하기 위한 강성을 가지는 판 부재(1)와, 상기 압력 기울기에 의해 가속된 공기의 입자 속도의 에너지를 소비하기 위해 상기 판 부재의 에지 부근에 배치된 흡음재(2)를 구비하였다.
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.
