Claim:
1. A method for identifying one or more resonance peaks of an actuator of an auditory prosthesis configured to deliver mechanical stimulation to a recipient, comprising: applying a test voltage to the actuator at a plurality of frequencies over an operational frequency range of the actuator to cause actuation of the actuator; measuring at least one of a voltage across the actuator or a current through the actuator for each of the applied test voltages at the plurality of frequencies; analyzing the measured values to identify at least one resonance peak of the actuator; generating a driver signal based on the identified at least one resonance peak; and providing the driver signal based on the identified at least one resonance peak to the actuator thereby to cause a hearing percept by the recipient, wherein the actuator is configured to move in a reciprocating manner to output vibrations to evoke a hearing percept by the auditory prosthesis, and measuring at least one of the voltage or the current comprises:
