摘　　要：计算机模拟室内声场已经成为声学研究的一种有效方法,声源的数学算法对室内声场的分布模拟有很大的影响。利用等立体角,研究了室内声场的点声源模型的数学算法,并利用计算机进行了模拟;点声源的算法将为室内声场中声线的跟踪和声场的模拟提供了有力的工具。Room acoustic computer simulation became one effective method for acoustic research, the algorithm of point source had an effect on the distribution of acoustic fields. The algorithm of point source in room acoustic fields was studied by using solid angle assumption, and the sound rays were simulated by using computer. The algorithm of point sound source will offer a powerful tool for ray-tracing and computer simulation.
