Schroeder Diffusers: A Review

Schroeder diffusers revolutionised the design of scattering surfaces when they were invented in the 1970s. For the first time diffusers with defined acoustic performance could be easily designed. Since their inception, much has been learnt about the performance of the surfaces. Limitations of the original concepts have been studied, and solutions found to overcome many of these. This paper will review the development of this technology over the last three decades.
