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