摘　　要：Odeon建筑声学设计软件是目前建筑声学领域进行建筑声学设计及仿真计算最为成功的软件之一.借助该软件,笔者在概述其基本功能及工作流程的同时,以一个现有的多功能厅堂的建筑模型为例,考虑舞台上只有一个点声源,在听音区域选择了6个有代表性的听音位置,计算了多个声学参数,然后全面分析声学参数的分布状况.在声学分析的基础上,评价厅堂声学设计的优劣,最后指出该厅堂各项声学指标仍有诸多不妥之处,为使厅堂的声学性能满足要求,还必须对厅堂的扩散和吸收特性做仔细调整.As architecture acoustics design so.are, Odeon is a very successful software in architecture acoustics field which can do acoustical design and simulating computation. Using this so.are, the paper first introduces its basic functions and work flow, then selecting a multiply purposes hall as an example, only considering a point sound source on stage, selecting six representative sound receiver positions in listening area, several acoustical parameters are computed, and the computation results are analyzed. Depending on acoustical analysis, advantage and disadvantage of hall acoustical design are evaluated. Finally the paper points out that some acoustics parameters of the hall still can＇ t meet design requirements, in order to make the hall be better acoustical performance, diffusion and absorbability characteristic must be adjusted carefully.
