| Abstract: | A model of four-pole parameters,analogical with the mechanical four-pole parameters method,is introduced to analyze the transmission and reflection of acoustic wave in the interface of two different mediums according to the boundary conditions.The propagation of acoustic wave in multilayered medium is studied by the analysis for the four-pole parameters matrix on the condition of vertical incidence of a simple-harmonic plane wave,and the general formulas of the transmission coefficient and the reflection coefficient are presented. |
