Summary:

This paper studies the transmission loss of bounded double panel lined with poroelastic medium. Hamilton variational principle is used to derive the equation of motion. Kirchhoff hypotheses are assumed for the displacement field of the panel and Biot constitutive equations are used to model the poroelastic core. Resonant and non-resonant sound transmissions are investigated. Equivalent stiffness constants of the panel are presented. The results of the transmission loss based on the derived equation are compared with classical results
