Abstract:This paper introduces the process of pass by noise of heavy truck Inland or aboard， then we mainly discusses the noise source of domestic heavy trucks and the methods of reduction the noise.Through the specific engineering example，the main methods were verified.The result tells us that the methods are effective and there are the mainly measures for coutrolling the noise of heavy trucks.At last，we suggested that engineers should pay attation to the noise performance of trucks at the development initial.
