声学扩散体及界面声散射研究进展

摘要

The development of acoustic diffuser from the 1960s is summarized. The typical diffusers and its acoustics scattering characteristics are demonstrated. Then the paper states how the scattering property of a diffuser could be defined and measured. The initial investigations on the effect of surface scattering on room acoustics are introduced. In the end a series of questions relating to sound diffusion that need further investigated are pointed out.%本文介绍了声学扩散体的设计发展历程、典型扩散体的形式及其散射性能的影响因素以及界面声散射的定量测试及其对室内音质的影响的研究进展,并提出在声散射研究方面仍有待解决的问题。
