Abstract : The power balance equation in structure subsystems was demonstrated. Basic assumptions of semi-infinite fluid method were introduced. The prediction model of car exterior noise was built by using statistical energy analysis (SEA) and semi-infinite fluid method. Using finite element method, steady-state energy flow method and theoretical computation, the modal densities, damping loss factors and coupling loss factors of the subsystems of car SEA model were acquired. The excitations of the car SEA model were got by experiment and computational fluid dynamics method. The car exterior noise was pr
