Abstract：The incident sound wave model of underwater sandwich structure with cavum was built. A new computing method of acoustic property was present, with the study of transmission in rigid tube, and coupling of acoustic and structure. Through the contrast of acoustic properties with the midway layer of steel, rubber, the single sandwich, and sandwich rudder, the computing method was verified. The acoustic property of reference anechoic layer with cavum was researched. By this method, the acoustic property of influence of whole bent vibration was analyzed. The effect of boundary condition of period cavum could be ignored.
