Methods for assessing a position of an actuator of an implantable hearing aid transducer relative to an auditory component of a patient. According to one aspect of the invention, an implantable hearing aid transducer is located in proximity to the auditory component of the patient. A test signal is provided to the patient to stimulate the auditory component and generate an acoustic response in the ear canal of the patient. The acoustic response is detected and utilized to assess the position of the actuator of the transducer relative to the auditory component.
