摘　　要：介绍了使用EASE软件对中国传媒大学小型影院进行声场建模的方法,并同时采用MLS序列法测得该影院的房间脉冲响应,通过脉冲响应反向积分法提取出该影院的客观声学参数。最后对这两种方法得到的数据进行对比分析,发现了计算机声学模拟中存在的一些问题,希望能对计算机声学模拟的研究提供帮助。This paper introduces the acoustic modeling of a small theater of Communication University of China by EASE in detail,and at the same time uses the MLS sequence to measure the room impulse re-sponse of the theater,then extract the objective acoustic parameters of the theater through integrated im-pulse response method. Finally,I contrast and analysis the data obtained by these two methods,and find some problems existing in computer simulations of the acoustic. Hoping to make some help for the study of computer simulations of the acoustic.
