室内界面声散射特性的评价与测量的研究进展

Progress in research of characterization and measurement of sound-scattering properties of room surfaces

结合AES和ISO对室内界面声散射特性两种不同的评价方法 ,分别了介绍扩散系数和散射系数的定义及其测量方法。通过比较这两个参量 ,指出各自的特点和适用范围。同时 ,对目前研究中存在的问题进行了讨论 。

Definitions and measurement methods of 'diffusion coefficient' and 'scattering coefficient' are presented. Two parameters, AES and ISO, are introduced respectively to characterize the sound-scattering properties of room surfaces. Their features and the application scope are examined. Problems existing in current researches that need further investigations are also discussed.
