1. A method of analyzing acoustic data of a pump, the method comprising:

  • operating the pump at a given speed;

    recording the acoustic data from the pump over a series of time periods during said operating;

    averaging acoustic data of the multiple cycles to minimize an effect of any inconsistent acoustics by stacking waveforms from the recorded acoustic data into a single averaged waveform;

    enhancing the acoustic data for analysis;

    determining upper and lower thresholds of magnitude for the recorded acoustic data based on the enhanced data; and

    thresholding the acoustic data for identifying any acoustic event correlated to the speed.
