摘要
为实现封闭空间声场的计算机模拟,在声线跟踪法基础上,提出了变径声粒子跟踪方法,该方法有效的解决了在经典声线法中接收区域的选取影响仿真效果这一难题。在VisualBasic6.0的基础上编制了仿真软件,仿真实验结果表明,该方法是可行的。
To complete the computer simulation for sonic field in an enclosure,based on the ray tracing method,the method of sonic particles with changing diameter is given.With this method,the difficult problem of selecting a suitable receiving area,which stongly effects the simulation results in typical ray tracing method,is solved.Using the method,an simulation pro-gram is made based on Visual Basic6.0,and the simulation experiment results show that the method is feasible.[
