Acoustic Diffuser is consist of grid caisoons with different depths, it could reflect different frequency sound waves by different depth of caisoons omnidirectionally with diffusing in the same process of reflecting, which makes the sound fruity and euphonic, and reach the audience from overhead, flank side, front side, sharply improve the acoustical effect.

Wooden Acoustic Diffuser is a anomalous plane which could make sound diffusing while reflecting, that makes the sound fruity and euphonic, and reach the audience from overhead, flank side, front side, sharply improve the acoustical effect.

Principle of diffusing:When sound wave make incidence to horizontally placed QRD diffuser, it could reflect the sound at same intensity between 30º~150º

Absorption:QRD Diffusers made of different woods have different sound absorbing feature, it could be customized according to the design.

Material: maple wood, birch wood, pine wood, beach wood, HDF board etc., different woods with different features.

Flaws of planar reflection:The planar reflection from flat flank wall makes the sound and voice harsh and acerbity, while Acoustic Diffuser could remain the quality of the sound.
