1. A method, comprising:
attaching a transducer assembly to a resonating surface of a vehicle, the transducer assembly comprising a piezoelectric assembly spaced apart from the resonating surface;
receiving, by the piezoelectric assembly, a kinetic vibration resonating from the resonating surface; and
generating, by the piezoelectric assembly, an electric output signal associated with the kinetic vibration.
