本文叙述一种用计算机来模拟室内声传播的方法,用此法可以在厅堂建成以前评价音质。数字模拟方法还可以研究室内声学中的许多基本问题,例如初始时间间隔的作用、一次反射声的重要性、回声的分布等。一个房间可以看作线性无源网络,房间内不同点之间的声波传播可以用电网络来模拟,以产生舞台上某点和听众两耳之间的脉冲响应。电网络的模拟类似于数字计算机上的抽样数据控制系统。其模拟的方法如图1所示。一个没有混响的声信号(在消声室内录 This article describes a computer simulation of indoor acoustic transmission method, this method can be used to evaluate the sound quality in the hall built. The digital simulation method can also study many basic problems in indoor acoustics, such as the role of initial time intervals, the importance of primary reflections, and the distribution of echoes. A room can be thought of as a linear passive network. Acoustic propagation between different points in the room can be modeled using an electrical network to produce an impulse response between a point on the stage and the listener’s ears. The electrical network simulation is similar to the sampling data control system on a digital computer. The simulation method shown in Figure 1. A no reverberation sound signal (recorded in the anechoic chamber
