Schroeder Diffuser

This is a sound-diffusing panel based on a square residual value sequence for scattering sound reflections, usually in one or two dimensions (horizontal/vertical). The diffusers apply in particular to editing rooms, smaller listening rooms, and recording studios. However, also larger rooms benefit from the diffusion of hard reflections, which preserve most of the sound energy (in opposition to the absorption of the sound energy). The physical depths of the panel decide the efficient frequency range. The principle is invented by the German physicist Manfred Robert Schroeder (1926-2009).
