- 2 ) in order to solve the scattering and diffraction of sound radiation , in this dissertation , based on helmholtz equation and its boundary equations , modeling of three - dimensional fem is given for computing low frequency sound transfer function in small enclosures
2 )为解决声音在传播过程中所发生的散射和衍射现象，本文基于有源helmholtz方程及其边界条件，建立了求解小尺度封闭空间内低频声传递函数的三维有限元模型。 - Boundary condition method just amend a little for intrinsic fem program , and can obtain low frequency sound transfer function of receiver based on existed fem mesh . the big sound source is divided into some elements by lumped sound source method , in which , the biggest size of element is smaller than the smallest wavelength of sound wave
边界条件法仅对原有的有限元程序作较小修改，并在已有的有限摘要元网格划分上，能够求解出接收点处的低频声传递函数;集中声源法将大尺度声源划分为若干板块，其最大几何尺寸小于最小声波波长。 - Considering the time delay of sound transfer , a least square line - of - sight location method is presented in this paper . 4 . filtration matrix is developed to make the problem of multiple target tracking in net can be regarded as a problem of multisensor - multitarget tracking in a same region
