QRDdiffuser

QRDdiffuser is a type of acoustic diffuser designed to scatter sound waves. It is based on the Quadratic Residue Diffuser (QRD) principle, which utilizes a sequence of wells of varying depths. The specific depths are determined by a mathematical sequence derived from quadratic residues modulo a prime number. This arrangement causes incoming sound waves to reflect and spread out in multiple directions over a range of frequencies. The effectiveness of a QRDdiffuser is dependent on its design parameters, including the number of wells, the depth of the wells, and the width of the wells. These diffusers are commonly used in acoustical treatments for rooms such as recording studios, concert halls, and auditoriums to improve sound quality by reducing echoes, flutter, and reverberation. By breaking up direct sound reflections, QRDdiffusers help to create a more uniform and pleasing sound field. They are typically constructed from materials like wood, plastic, or fiberglass, and can be custom-designed to meet specific acoustic requirements.
