1. A method of calibrating a high-frequency reciprocal transducer, the method comprising:
directing a source toward a diaphragm of a reciprocal transducer;
coupling a first oscillating voltage with an electrical connector of the reciprocal transducer;
comparing a deflection pattern of the diaphragm to known specifications of the reciprocal transducer, wherein the deflection pattern is caused in part due to the first oscillating voltage coupled to the electrical connector; and
signaling when a correlation between a magnitude of the deflection pattern with the first oscillating voltage as a function of a frequency of the first oscillating voltage meets or exceeds a calibration correlation condition.
