Popis: A direct coupling procedure of the finite element method (FEM) and the boundary element method (BEM) for structure-acoustic-cavity problems has been introduced. The Laplace transformed matrix equations for the structure and acoustic cavity are coupled directly satisfying the necessary equilibrium and compatibility conditions. The coupled FEM-BEM technique is verified using a box-type cavity for the steady-state and the transient predictions compared with analytical results. The verified coupled FEM-BEM code is utilized in the analysis of the earmuff-earcanal system.
