1. A method for analyzing a vibration event comprising:

  • acquiring a vibration signal;

    isolating a vibration signal event in the acquired signal;

    determining a natural frequency of the vibration signal event, using a damped sinusoid corresponding to the natural frequency to characterize the vibration signal event, and using the characteristic damped sinusoid to identify an occurrence of the vibration signal event in another vibration signal.
