In this paper, the thickness of the different layer of the multiple-layer homogeneous structure. is optimized designed on the condition that the absorption effort is the best Using the transfer matrix of sound pressure and particle velocity of each layer and the continuity condition at the interface between two lagers, the absorption coefficient of the multiple-layer homogeneous structure is deduced. According to the absorption coefficient, the thickness of different layer is optimized designed on the condition that the absorption effort is the best when the sound wave incident to the multiple-layer homogeneous structure with different frequency. In the last, an experiment is carried out, and the experiment results test the theoretical analysis is correct which can be applied to solve the same kind problem.
