摘　　要：长久以来,人们对声学模拟软件EASE(无论版本高低)预测的一些室内声学参量数据结果都深信不疑,并以此为依据,致使在某些厅堂扩声系统工程招标中,将其作为工程设计标书中一个不可或缺的设计要求。笔者多年来对EASE软件不同版本及不同运算模块研究结果表明,上述观点在认识上存在很大的局限性。为了更深入认识和理解该软件,本文以EASE不同运算模块对同一厅堂声学参量运算结果进行对比、分析和讨论,得出EASE软件中只有AURA运算模块才能真正适用于厅堂扩声系统非扩散声场环境下的声学模拟。The simulation results of room acoustics parameters data by the software EASE （regardless of version level） are worth trusting, which are used as one of the design requirements in bidding book for a long time. With the research of different version and operation modules, the hmitations of the above-mentioned point is shown. In order to recognize and use the software, the results of the room acoustics parameters for the same room using different operation modules are compared, analyzed and discussed. The analysis shows that only the AURA module is suitable for the acoustical simulation on the sound reinforcement system in non-diffuse field.
