| Abstract: | We make an analysis on the frequency spectrum and the test result after measuning the noise raised from a centrifugal fan used in a mess hall. This paper advances a measure to suppress the noise. We have designed and made a suppressing noise device. The Noise has been greatly lowered after the use of the device, and the residential enviroment and the worker's working conditions are improved. |
