The automobile noise control

通过分析汽车噪声的来源和噪声控制的一般方法,提出了降低汽车噪声的一些方法及措施。汽车是一个复杂的噪声源,其主要来源是发动机。所以要想有效地降低汽车的噪声,就应该搞好对发动机噪声的控制。发动机噪声主要包括燃烧噪声、机械噪声和进排气噪声。因此,提出了降低燃烧噪声、机械噪声和进排气噪声的具体方法。

The automobile is a complex noise source, and the engine is predominant. Therefore the effective way to reduce the noise is concerned about the engine noise that includes the burning noise, the mechanical noise and the exhaust noise. Through the analysis of automobile noise origin and the noise control method, it proposes some methods that can reduce the noise.
