摘要
本文简要介绍了声场脉冲响应计算机模拟技术的基本状况，给出了一种将虚源法和声线法相结合的模拟方法－圆锥束跟踪法的原理和算法，并将其对一个实例的计算结果与虚源法进行了比较，最后对其实现过程中需要注意的问题进行了讨论。
Techniques using a computer to simulate the impulse response of an acous tical field in an enclosure are briefly mentioned. The principle and the algorithm of the conical beam tracing method(CBTM) which combines the image source method(ISM) and the ray tracing method(RTM) is presented. As an example, the impu1se response of a room model is calculated by using the CBTM and the ISM,and the results are compared. Some problems that should be paid attention to are discussed.
