抄録

This paper is concerned with the problem of the sound transmission loss through a three-layered cylindrical shell subjected to inner plane acoustic waves. Each layer of the shell is modeled as a single shell, and the whole shell equations are connected together through the assumption that the displacements and the tractions are continuous at the shell interfaces. Sound transmission loss TL is calculated for various combinations of the facings and the core with different physical properties, Further, the acoustic design method of the layered shell with high transmission loss is presented and illustrated with some examples.
