中文摘要:
      如何求解封闭空间中声源点到接收点的低频声传递函数已成为目前小尺度封闭空间可听化技术研究的关键问题。具有较高计算精度并能够处理任意结构形状的有限元素法可作为求解该问题的合适的方法。本文推导出了用于小尺度封闭空间低频声传递函数的有限元素求解方法,并编制了相应的计算机程序。最后在算例中通过与经典模态迭加法给出的结果进行比较,验证了该方法的正确性。
英文摘要:
      How to computing low frequency sound transfer function from source to receiver in enclosed room has become key problem in small enclosed room auralization. Due to high computing precision and processing arbitrary structure shape, finite element method (FEM) can become proper method to solution this problem. In this paper, firstly, FEM was given for computing low frequency sound transfer function in small enclosed room; secondly, computer program was written; finally, comparing with classical mode superposition method, FEM issued in this paper is efficient.
