Statistical Energy Analysis has been widely applied to improve the accuracy of the prediction of vehicle interior noise. Especially, in airborne noise cases, SEA is very useful for predicting the Interior noise ofa vehicle if some parts of the vehicle model are changed. In this paper, a building and validating process of the full vehicle SEA model is presented. First, Sound Transmission Loss and Absorption Coefficient (α) of vehicle components were measured using a real vehicle. An airborne SEA model was built using the geometry information, and the component characteristics were modeled using STLs, and α's, which were measured or calculated. Then, the interior and exterior noises of a full vehicle were measured for various experimental conditions such as WOT (wide open throttle) condition and loudspeaker loading conditions, which were used for the validation of the SEA model. Finally, the predicted and the measured interior noises were compared, and the accuracies of the SEA model were identified for several loading conditions.
