1.設(shè)備機械在正常運行進(jìn)體交換時產(chǎn)生的噪音，比如說風(fēng)扇或者是發(fā)動機，或者是發(fā)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(shè)備，在運行時，他由于產(chǎn)生震動的噪音也成為結(jié)構(gòu)噪音，那么這類噪音一般是由這個大功率高轉(zhuǎn)速的發(fā)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(shè)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(jìn)行：

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

　　一是在產(chǎn)生噪聲原處進(jìn)行減低分貝或消音處理，例如發(fā)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(zhì)減散它的傳播質(zhì)量，例如排風(fēng)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(zhì)進(jìn)行控制，例如風(fēng)扇等。

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