Noise barriers made with AGRESLITH-AC® are highly sound absorbent. They reduce noise of highways, railways or industrial noise sources by absorbing the sound and transmitting it through the cavities in the wall due to its porous surface. The energy is forced to follow a longer path over and around the barriers.
