To solve the acoustic transmission problem in multi-layered, it represents the acoustic on the even(or odd) layer in the form of combined double and single-layer potentials, and then gets the acoustic on the rest layer and boundary integral equation by Green theory.The traditional boundary element method will eventually form 2M boundary integral equations with domain of M layers, and half of the equations can be reduced by applying the method above. Finally, the numerical examples were given to test the accuracy and feasibility of the method.
