1.设备机械在正常运行进行气体交换时产生的噪音，比如说风扇或者是发动机，或者是发电机等。

1. The noise generated by gas exchange during normal operation of equipment machinery, such as fans, engines, or generators.

　　2.还有就是设备，在运行时，他由于产生震动的噪音也成为结构噪音，那么这类噪音一般是由这个大功率高转速的发电机运动而造成的。

2. Another issue is the equipment, which generates structural noise due to vibration during operation. This type of noise is generally caused by the movement of this high-power and high-speed generator.

　　设备噪音的控制方法

Control methods for equipment noise

　　对于滑模机的噪声控制，我们从以下三个原则来进行：

For the noise control of sliding mode machines, we follow the following three principles:

　　一是在产生噪声原处进行减低分贝或消音处理，例如发动机动力噪声。

One is to reduce decibels or attenuate noise at the source of the noise, such as engine power noise.

　　二是在传播的过程中通过一些介质减散它的传播质量，例如排风扇等。

The second is to reduce its propagation quality through some media during the propagation process, such as exhaust fans.

　　三是在传播过程中对介质进行控制，例如风扇等。

The third is to control the medium during the propagation process, such as fans.
