Abstract: The rules of the China vehicle noise control are summarized. By analyzing the sources of vehicle noise, the important parts of vehicle noise are introduced. The main control technology and measures of reducing the noise of vehicles are presented. Because of the complexity of the vehicle noise control, at present there are a lot of technology and applications are blank in the research area.Reduce vehicle noise is an important subject of future automotive technology.

Abstract: In this paper, we analysed the level of radiation noise and distribution of noise sources of car’s engine and front panels by using sound intensity method. To get the nephogram of sound intensity and sound power spectrum, we used the sound intensity probe and Multi-channel Data Acquisition Regulation System B&K 3560-D and Pulse Data Processing Analysis Software. By analysing experimental results, we can conclude the location of noise sources of these parts. The measurement results will serve as a reference for the car noise reduction.
