Governing equations for the forced vibration of asymmetric sandwich panels are developed from energy relationships. A wave impedance analysis model for the sound transmission loss of asymmetric sandwich panels is presented. The wave impedance analysis model is compared with other wave impedance analysis models for sandwich panels. Comparisons between predictions of the sound transmission loss of two sandwich panels obtained from two wave impedance analysis models for asymmetric sandwich panels are given.
