摘　　要：主要采用有限元的思想,并借助ansys软件对室内声压分布进行模拟,逃避了建立固体模型的繁琐,仅建立流体模型,通过制定流固界面、输入阻抗、吸声吸声,以及边界条件等相关因素,仍然准确、便捷的得到了声压的分布曲线和特性规律。对室内声学设计提供了有力的理论参考,为建筑声学提供了便捷的思路。This paper mainly adopts finite element method to simulate interior sound pressure distribution by using the ansys software.It escapes from establishing solid model, only to establish fluid model.We can also get precise sound pressure distribution curve and characteristics law by formulating fluid-solid interface, input impedance, acoustic absorptivity, boundary conditions and so on.So it can be reference and guide for the interior acoustic design, and then it provides convenient train of thought for the architectural acoustics.
