This paper describes the analysis method of the cuboid acoustic field including an acoustic absorption material whose shape is also the cuboid. The acoustic field was analyzed by two methods: one method installed a significantly light and flexible plate into the interfacial boundary, and the other method used an acoustic field whose interfacial face was opened. The characteristic of the acoustic absorption material was represented using complex density and complex bulk modulus. The effectiveness of the proposed method was verified through the comparison of simulation results using the proposed method and exact solution.
