摘要
There is provided a method for troubleshooting noise/vibration issues of rotating components, the method comprising: receiving an audio signal of the rotating components in operation; generating a frequency spectrum corresponding to the audio signal; selecting a frequency νm in the frequency spectrum corresponding to a maximum amplitude; and comparing the frequency νm to a set of predetermined rotational speeds of the rotating components to find a match; thereby identifying a potentially defective component.
