Causes of Fan Noise Noise emanating from axial fans is a function of many variables and causes: Whirl pooling: This is a broadband noise source generated by air separation from the blade surface and trailing edge. It can be partially controlled by good blade profile design, proper pitch angle and notched or serrated trailing blade edges.

Spectrum Analysis - SKF

Identifying fan or vane pass frequencies, if applicable, hel ps determine if a fault is present. Identifying the number of gear teeth and the shaft on which the g ear is mounted, if applicable, helps determine if a fault is present. Moreover, this helps determine if there is a problem with a part icular gear.
