Product Features

Main features: QRD diffuser is a sequenced grid that is calculated strictly according to the QRD theoretical formula. Its groove depth and width can produce uniform diffuse reflection under omnidirectional and multi-angle incident sound conditions. It makes the human voice more supple, the high frequency becomes more full, and makes the small space have the effect of the hall.


Compared with flat reflectors, QRD diffusers 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 QRD 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 QRD diffuser is when the reflective surface is a QRD 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. 


QRD diffusers 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 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.


Scope of application

Scope of application: Theaters, concert halls, vocal rooms, recording studios, audio-visual rooms and other places with high sound quality requirements.
