| 摘 要： | 针对ODEON建模仿真,选取两个有代表性的厅堂,通过改变模型的精细程度比较分析声学指标的模拟值与实际测量值。结果表明:(1)模型精细程度会影响仿真声学指标;(2)模型中细小的结构与表面会使仿真得到的低频混响时间增加;(3)精细模型下中高频段的声学指标模拟值更接近实际测量值;(4)合理简化模型可以提高ODEON软件仿真的效率。

| Abstract: | Based on ODEON, by changing the elaborate degree of two different halls＇ models to comparative analysis a- coustic index simulated values and actual measured values,this paper presents that （ 1 ） Model＇ s elaborate degree will affect the simulated acoustic indexes. （2）Fine structure and tiny surfaces in models can improve the simulated low-frequency re- verberation time. （3） In elaborate models, acoustic index simulated values in middle and high frequency are closer to the ac- tual measured values. （4）Simplifying models reasonably could improve the efficiency of the ODEON software simulation. |
