Abstract

In this study, vehicle air-borne and structure-borne noise sources and noise transfer paths arc identified. By applying the interior noise source contribution and transfer path analysis method, the contribution of each noise source in the vehicle is calculated by subsystem level measurements. Moreover, the actual vehicle level interior noise has been measured and compared with the calculated levels for correlation. When good correlation is achieved, a critical peak level, which may be a potential NVH problem, has been investigated with the measured and Calculated data.
