中文摘要:
      时域有限差分法将声波基本方程表示为一个时间和空间的迭代方程组,实现对室内声场中低频段的模拟计算.在介绍时域有限差分法基本原理的基础上,着重探讨采用时域有限差分法模拟室内声场时边界条件的处理方法及该方法在室内声场模拟中的应用.分析了该方法存在的一些问题及其应用前景.
英文摘要:
      Sound field in rooms at low frequency can be simulated by using finite difference time domain method,which expresses the acoustical wave equation in a serial spatial and time iterative equation groups.In the paper,the basic principle of finite difference time domain method is introduced.It is emphatically discussed that the processing method of boundary condition and the application of using finite difference time domain method to room acoustical field si-mulation.The existing problems and prospective of this method are also analyzed.
