1.設備機械在正常運行進行氣體交換時產生的噪音，比如說風扇或者是發動機，或者是發電機等。

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

　　2.還有就是設備，在運行時，他由于產生震動的噪音也成為結構噪音，那么這類噪音一般是由這個大功率高轉速的發電機運動而造成的。

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.

　　設備噪音的控制方法

Control methods for equipment noise

　　對于滑模機的噪聲控制，我們從以下三個原則來進行：

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

　　一是在產生噪聲原處進行減低分貝或消音處理，例如發動機動力噪聲。

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

　　二是在傳播的過程中通過一些介質減散它的傳播質量，例如排風扇等。

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

　　三是在傳播過程中對介質進行控制，例如風扇等。

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