| 中文摘要: |
| 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,以期为进一步的研究提供参考。 |
| 英文摘要: |
| 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. |
