Diffusors are used to treat sound aberrations in rooms such as echoes. They are an excellent alternative or complement to sound absorption because they do not remove s, but can be used to effectively reduce distinct echoes and reflections whilee. Compared to a reflective surface, which will cause most of the e be reflected off at an angle equal to the angle of incidence, a diffusor will cause the sound energy to be radiated in many directions, hence leading to a more diffusive acections in time as well as spatially. Diffusors can

QRD diffusors are designed to diffuse sound in either one or two directions. Fractal constructions can be used to extend bandwidJK

QRD diffusors are widly used in studio room, negotiation rooms, reception hall and all kinds of cultural and entertainment places.
