The efficient insulation of noise transmitted from the powertrain is one of the important issues in developing the variation or minor change of the vehicle. This paper deals with the contribution analysis of each path of interior noise by window mask method using air-borne noise transfer function and shows the application of Taguchi method in finding the best combination of the insulation countermeasures. To this aim, the vehicle interior cabin is segmented into 25 windows and the air-borne noise transfer functions between source and receiver points are measured by acoustic reciprocal method.
