Acoustic Absorbers and Diffusers. Theory, design and application. Trevor J. Cox. University of Salford, UK and. Peter D'Antonio. RPG Diffusor Systems Inc., USA. The book 'Acoustic Absorbers and Diffusers: Theory, design and application' has been one of the most popular and useful books in the area of. Acoustic Absorbers and Diffusers.

Get Citation Cox, T. Acoustic Absorbers and Diffusers. Surface diffusion is a relatively young subject area, and diffuser design, application and characterisation are often not well understood. Although there is greater knowledge of absorption, it is also informed by new research. As two of the main design tools for altering the acoustic conditions of rooms, the correct use of absorbers and diffusers is important to the creation of quality acoustics.

Pal, J. Kalinova, QSci. The birth of modern diffusors was marked by Manfred R. Schroeders ' invention of number-theoretic diffusors in the s. Maximum length sequence diffusors[ edit ] MLS Diffusor Maximum length sequence based diffusors are made of strips of material with two different depths.
The placement of these strips follows an MLS. The width of the strips is smaller than or equal to half the wavelength of the frequency where the maximum scattering effect is desired.
Ideally, small vertical walls are placed between lower strips, improving the scattering effect in the case of tangential sound incidence. The bandwidth of these devices is rather limited; at one octave above the design frequency, diffusor efficiency drops to that of a flat surface.
Quadratic-residue diffusors[ edit ] Hz Quadratic-Residue Diffusor MLS based diffusors are superior to geometrical diffusors in many respects; they have limited bandwidth.
The new goal was to find a new surface geometry that would combine the excellent diffusion characteristics of MLS designs with wider bandwidth. A new design was discovered, called a quadratic residue diffusor. Quadratic-Residue Diffusors can be designed to diffuse sound in either one or two directions.
They too suffer from "flat plate" frequencies, but at a higher frequencies than MLS diffusors.
