The quadratic residue diffuser can be used to dissipate sound energy, prevent echo and standing waves, play the role of omnidirectional diffusion, improve the brightness of the sound.

Compared with flat reflectors, QRD sound diffuser can effectively avoid acoustic focusing. When the sound wave passes through the plane reflector, all sound energy will be reflected in the same direction, its reflection direction is fixed, the direction of reflection depends on the location of the sound source. And when the sound wave is reflected by the surface of the diffuser, sound energy will be scattered and reflected in different directions, and have different phase differences.

These irregular vibrations of uniform energy can subjectively create a sense of space for the human ears. At the same time, it will increase the brightness of the sound when it is diffused in the middle and high frequencies. Its reflection direction is roughly a semicircle, and the sound energy will be averagely diffused. Another effect of quadratic residue diffuser is when the reflective surface is a solid wood strip diffuser, because sound waves diffuse in a semicircular direction, there are countless reflection paths of different frequency bands converge at the listening position, and so forth, there are countless convergence points of the same nature, this will invisibly expand the listening area. 

The quadratic residue acoustic diffuser can be used not only to dissipate sound energy, play the role of preventing echo and standing waves. At the same time, it can improve the brightness of the sound. Appropriate addition of QRD acoustic diffuser on the early reflection path reflects high frequency near 2K can increase brightness, and can significantly improve the sound quality if cooperate with sound absorbing materials.


High-end indoor sound quality sound reinforcement decoration for theaters, concert halls, leisure clubs, private theaters, recording studios, HIFI listening rooms, etc.
