　　There are two main reasons for turbocharger whine noise in vehicle, unbalance and pressure pulsation, and they have the same characteristic but different mechanism.The different methods are studied in this paper to improve the different whine noise.Nonlinear order pick-up method is applied in analysis of whine noise contribution and the objective evaluation standard about turbocharger? whine noise is established.
