| Abstract: | The wave propagation and its control in a cylindrical shell are studied. The interaction between different types of wave and its variation with frequency are analyzed. From the point of view of noise control, the effects of the flexible joints in the shell, such as the rubber joint, are discussed. Waves of different circumferential modal numbers due to flexural vibration are regarded as incident ones to the joint and the resultant transmission losses are evaluated from the amplitudes of the incident and transmitted waves using power equations developed in this paper. |
