Abstract :
The acoustic scattering problem is solved and an example is calculated using the finite element/infinite element method. Firstly, the surface velocity is obtained by the incidence acoustic wave and the characteristic of structure. Then the surface pressure is solved using the finite element/infinite element method. Lastly, the frequency of the incidence acoustic wave changes for the error of this method. This problem can be solved by finite element/infinite element method efficiently. Furthermore, the solving error is relatively low in a large frequency range.
