This paper presents to predict the reduction of booming noise in the cabin of the tractor using hybrid method. In this approach, The well correlated FE model and acoustic model were created. Noise and vibration characteristics of the tractor are studied systematically because PWT sources of the tractor that contribute to the interior noise can be analyzed. Experimental loads measured by Transfer Path Analysis are used for full tractor analysis. As a result of this study, the booming noise is predicted by using hybrid method and reduced effectively by design modification.
