Abstract : For predicting in-car noise in intermediate frequency range, firstly the subsystems of car body are divided to build a hybrid FE-SEA model for car. Then by combining theory and test, the modal density and interior loss factor of car body structure as well as the radiation efficiency of body panels are obtained. And the excitation on engine mounts and the excitation of road to car body at connecting points between suspensions and car body are determined by theoretical calculation. Finally the noise at driver's right ear is predicted by using both hybrid FE-SEA model and SEA model respectively,
