| 摘 要： | 当使用音质仿真软件ODEON进行模拟时,建模精细程度对一些音质参量的影响较大,与散射系数取值的关系也非常复杂。本文在对比ODEON9.0与以前版本模拟算法区别的基础上,使用不同精细程度的模型以及不同散射系数对多个代表性厅堂进行模拟计算分析,验证了合适精细程度的模型可以获得可靠模拟结果的结论,并探讨了模型精细程度对混响时间T30、声能比C80的影响以及与散射系数取值的关系。

| Abstract: | When simulating the sound quality using ODEON software, the fine degree of modeling exerts strong influence on some sound quality parameters and the correlations between the scattering coefficient values and modeling fine degree are complicated. This paper first compared the simulation algorithm of ODEON9.0 and that of the previous version, then simulated and analysed more than one representative halls by using different fine degree models and different scattering coefficient, verified the conclusion that an reasonable fine degree model can obtain reliable simulation results, and discussed the influences of modeling fine degree to T30 and C80, and the correlations between scattering coefficient values and modeling complexity level. |
