This application shows how to find defective motor by detecting low level noise (buzzing, humming etc) in the motor sound. Finding features in low level noise via FFT analysis requires some skills. The OS-2760 fluctuation sound analysis pack enables you to figure out the features clearly such as frequency or fluctuation period cycle of the noise.
