摘要
文中以一个不规则空间为例，给出了虚源法模拟声场的基本原理和算法，介绍了由模拟所得的脉冲响应获取声场明晰度等参数的方法。针对虚源法计算量巨大这一突出问题，着重讨论了几种提高计算效率的方法，并在最后将虚源法与声线跟踪法作了简单比较。
In this paper, the algorithm and basic principle of image-source method simulating sound field are presented with the example of an irregular space. The acquired frequencyresponse by means of simulation can be used to get certain parameters such as sound fieldclarity. Several methods of improving the calculation efficiency are discussed in detail aimed atthe huge quantity of calculation of image source method. And at last the image-source methodis compared with sound ray tracing technique briefly.
