- In this paper, in order to calculate the acoustic scattering of the duct, a thin-body boundary element method (BEM) has been proposed and the velocity obtained by the acoustic velocity formulation is use1d as the Neumann boundary condition on a rigid scattering surface. The radiated sound pressure and the scattering effect of the solid wall on the propagation of the sound wave are calculated by using the Kirchhoff formulation and the thin-body BEM, respectively. Computational results for a monopole source verify the method. The sound pressure directivity and scattering effect are shown to demonstrate the applicability and validity of the approach.
