Diffusors (or diffusers) are used to treat sound aberrations in rooms such as echoes. They are an excellent alternative or complement to sound adsorption because they do not remove sound energy, but can be used to effectively reduce distinct echoes and reflections while still leaving a live sounding space. Compared to a reflective surface, which will cause most of the energy to be reflected off at an angle equal to the angle of incidence, a diffusor will cause the sound energy to be radiated in many directions, hence leading to a more diffusive acoustic space. It is also important that a diffusor spreads reflections in time as well as spatially. Diffusors can aid sound diffusion, but this is not why they are used in many cases; they are more often used to remove coloration and echoes.

Diffusors come in many shapes and materials:

Barrel Shaped Diffusors are perfect for applications that require a high degree of sound diffusion, such as music rooms, band rooms, and concert halls. They are lightweight and easy to install on walls using a 2 part clip system. Barrel Shaped Diffusers are constructed of high strength reinforced fiberglass molded in a one piece barrel shape and are available in a white gel-coat finish or optional fabric covered. Barrel diffusers are finely tuned to reflect sound.

Pyramid Diffusors are perfect for applications that require a high degree of sound diffusion, such as music rooms, band rooms, and concert halls. They are lightweight and easy to install in a standard ceiling grid or can be installed on walls with a 2 part clip system. Pyramid Diffusers are constructed of high strength reinforced fiberglass molded in a one piece pyramid shape. Pyramid diffusers are finely tuned to reflect sound and are available in a standard white gel-coat finish or optional fabric covered.

Two Dimensional ("Hemispherical") Diffusors Designed, like most diffusors, to create "a big sound in a small room," unlike other diffusors, two dimensional diffusors scatter sound in a hemispherical pattern. This is done by the creation of a grid, whose cavities have wells of varying depth, according to the matrix addition of two quadratic sequences equal or proportionate to those of a regular diffusor. These diffusors are very helpful for controlling the direction of the diffusion, particularly in studios and control rooms.

Quadratic-Residue Diffusors Quadratic Diffusors are a design derived by combining a standard quadratic residue sequence with other mathematical techniques, creating a profile that optimizes scattering surfaces. Sonically, this means more accurate control of sound reflections in your room without making the room sound flat.
