Development of optimum acoustic diffusers.

摘要: It is required for ideal acoustic diffusers that the incident energy scattered, without any loss of energy, in all directions with equal distributions. Quadratic-residue type were designed this aim. But it has become clear such also provide highly selective and inevitable absorption depending on both frequency angle incidence. In article, order to develop optimum diffuse reflections less sound, possibility realization discussed theoretically. A measure regarding statistics diffusion defined, which enables one evaluate performance diffusers. As a result, shown surface profile satisfies condition diffuser can be obtained difficulty manufacturing. The design procedure few examples are presented.
