QRDdiffuusorid
QRDdiffuusorid, also known as Quadratic Residue Diffusers, are acoustic treatment devices designed to scatter sound waves. Unlike sound absorbers that aim to reduce the amount of sound energy, diffusers work by breaking up sound reflections into many smaller, less coherent reflections. This process helps to create a more even and natural-sounding acoustic environment.
The design of a QRD diffuser is based on mathematical sequences known as quadratic residues. These sequences
QRDdiffuusorid are typically constructed from wood, plastic, or other rigid materials. Their effectiveness is dependent on
