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 determine the depths of the wells or chambers that make up the diffuser's surface. The varying depths of these wells are crucial for scattering sound across a range of frequencies. By having wells of different depths, sound waves are reflected back at different times, effectively breaking up the coherent reflections that can cause issues like flutter echo or a harsh sound.

QRDdiffuusorid are typically constructed from wood, plastic, or other rigid materials. Their effectiveness is dependent on the specific design, including the number of wells, the well depths, and the overall dimensions. They are often used in recording studios, concert halls, and home theaters to improve sound clarity and spaciousness. By diffusing sound, they can prevent sound from building up in certain areas and reduce the perception of unwanted sonic artifacts. The goal is to create a more immersive and pleasant listening experience by distributing sound energy more uniformly throughout a space.
