Schröder diffuser is a sound -diffusing structure used to improve room acoustics. It is a set of parallel recesses of the same width, but of different depths [1] . The diffuser is named after the inventor, Professor of the University of Göttingen, Manfred Schroeder , who developed this design after studying the acoustic parameters of more than 20 well-known European concert halls. The Schröder diffuser allows you to get a high degree of dispersion of the sound wave in a wide frequency range at any angle of incidence. The sound energy dispersion diagram of a one-dimensional Schröder diffuser is in the form of a half-cylinder.
Schroeder acoustic diffusers shift in space and delay in time early reflections from surfaces enclosing the room. They allow you to improve the acoustics of a small room by increasing the time of arrival of early reflections.
