Noise Source in Automobile and Control Method for Environmental Protection

Article Preview

Abstract:

As one of the environmental pollution sources, the noise problem in recent years has been as the focus of environmental protection control. As the noise pollution source, automobile noise has been studied in this article. At First, the influence factors of automobile noise are introduced, and then the major noise sources are all analyzed. Finally, three kinds of control methods such as noise control method from mechanical theory, from acoustic theory and active control method are introduced.
