These noises are conveyed through vibration of the interface structures between the acoustic fields. Transmission or insulation of noise can be investigated through analysis of coupled vibration between the acoustic field and the structure. It is widely used for reduction of noise to enclose the noise source by an appro- priate structure. It is an important subject in engineering to develop an optimal structure to insulate noises. The present paper is concerned with the development of an ac- curate, effici
