An octagonal noise diffuser Royal Diffuser is used as a finial of upper edges of noise barriers and is often employed to absorb diffracted sound waves. The use of the diffractor enables in some situations to lower a projected barrier’s height or to increase the efficiency of an existing barrier.

Royal Diffuser allows to increase screening capability from 2 dB to 3,5 dB, depending on noise frequency and placement of a barrier.
