| 摘 要： | 在考虑了壁面散射和声场耦合等因素的基础上 ,对传统庭院式戏场厢房内部的声场进行了详细的分析 ,分别用几何声学 (声像法 )和统计声学的方法模拟镜像和散射声 ,建立了厢房声场预测模型 ,所预测的客观参量强度因子G50 值与实测值能够较好地吻合 .通过理论模型 ,分析了直达声和来自舞台、厢房以及堂屋内的镜像声、散射声对厢房观众席G50 的贡献 ,并讨论了影响其响度的建筑设计因素 .

| Abstract: | The prediction model of sound-field in winghouse has been found based on the acoustic measurement for some Chinese courtyard theatres.Image-source method and statistical method are employed to predict specular reflection and scattering respectively,the coupling among spaces of the theatres being considered also.The model works well to predict the parameter G_ 50 which is in conformity with measuring results.Some important elements on the loudness of winghouse are dicussed through the model. |
