Quadratic Residue Diffuser (QRD) Explained
Diffusion in Acoustics is the even spreading of sound energy in a given environment. A perfectly diffuse sound space is the one where sound appears to be coming from all directions. An absorptive or reflective space can be converted into a diffusive space with the help of a diffuser, the most common one being the Quadratic Residue Diffuser (QRD). Learn more about sound diffusion and QRD in detail in this video. Read additional notes on QRD here: https://srinath96.blogspot.com/2024/0...
