Noise generated in the driveline is mainly transferred inside the passenger cabin through air (air borne noise) and through the vehicle body structure, engine mounts, cables etc. Source of the noise generation in the vehicle is mainly through the engine fluctuation (engine combustion excitations). Any change in the engine characteristics results in the change in passenger cabin noise. Also, influence of the vehicle body structure due to change in material properties also affects the NVH performance.
This technical paper explains the effect of change in engine characteristics as well as change in the transfer path (material property) on the NVH performance of the gearbox and subsequently the NVH performance of vehicle.
