| Abstract: | Finite element analysis of frequency response by sound pressure induction in vibro - acoustical couple system of a double cavity coupled by elasticity partition film is studied. The acoustical pressure distribution in acoustical cavity at peak pressure and the rektionship of the acoustical pressure change with frequency change in the responding cavity are disussed. The relationship of acoustical pressure distribution in a double cavity system is analyzed. |
