Abstract : The basic reciprocity relation for two sub-systems was demonstrated, and the hybrid FE-SEA equation was given too. Through numerical simulations, the hybrid FE-SEA model of a cavity-plate-cavity system was built, and the SEA model of the system was built at the same time. The modal density of the sound cavity and the coupling loss factor between the sound cavity and the plate were calculated, and the radiation efficiencies of the FE plate and the SE plate were also computed. The response of the cavity-plate-cavity system was calculated, and the response result of the FE-SEA model was compared
