通用小型汽油机及配套机具噪声控制方法

A Description of Noise Control of Universal Small Gasoline Engine and Its Mated Equipment

降低发动机噪声,一是通过优化设计降低产生噪声的声源,二是通过吸声、隔声、减振、隔振、消声等方法限制噪声的传播途径,各种方法、手段不是孤立单一的,需要针对实际情况加以综合运用。

For reducing engine noise, the first thing to do is to lessen the noise source which generates noise by means of optimizing the design and the second is to limit the propagation path of the noise by means of sound absorption, acoustic insulation, shock absorption, vibration isolation, noise elimination,etc. Bat these measures which are not unitary should be adopted accordingly and comprehensively.
