In this paper the free vibrations of two enclosures coupled through a flexible panel are studied by using plate and acoustic finite elements. The three dimensional problem is reduced to one of two dimensions by prescribing the solution in one direction, so while there is a restriction to have enclosures and panels of equal depth the geometry in the remaining plane problem can be irregular. However, the method is only applied in the present paper to simple rectangular enclosures.

The approximate equations for the system are deduced from a variational principle using a pressure formulation for the acoustic motion and displacement formulation for the plate. The resulting eigenvalue problem can be solved for the normal modes and natural frequencies of the complete coupled system. The results from the finite element model compared well with those obtained from experiments in both natural frequencies and coupled mode shapes.
