SOUND ABSORBENT BARRIER
흡음벽(10)은 다공성 제1커버(50)와 제2커버(60) 간에 배치된 흡음층(40)을 구비한다. 또한, 상기 흡음벽(10)은 제1커버(50)와 상기 흡음층(40) 간에 방수성 통음막(70)을 구비한다. 따라서, 상기 흡음층(40)은 상기 제1커버(50)와 제2커버(60)에 의해 손상이 방지되고, 상기 통음막(70)에 의해 침수가 방지된다. 상기 제2커버(70)는 비다공성이어서 상기 흡음층(40)을 통과한 음파를 다시 상기 흡음층(40)을 통해 반사한다. 또는, 상기 제2커버는 다공성이어서 두 방향으로부터의 흡음을 가능케한다.
A sound absorbent barrier has a sound absorbent layer disposed between a porous first cover and a second cover. The barrier also has a waterproof sound-permeable membrane between the first cover and the sound absorbent layer. The sound absorbent layer is thus protected from damage by the first and second covers and water ingress is prevented by the sound permeable membrane. The second cover may be non-porous to reflect sound waves which have passed through the sound absorbent layer back through the sound absorbent layer. Alternatively, the second cover may be porous to enable absorption of sound from two directions.
