    摘要: A system and method for detecting failures in an auditory stimulation device includes, in one embodiment, a microphone; a signal processor; a supercutaneous transmitter; a subcutaneous receiver; a subcutaneous transmitter; and a supercutaneous receiver. The signal processor generates a stimulation signal in response to the microphone detecting an audio signal, and the supercutaneous transmitter couples the stimulation signal through a skin surface of a patient. The subcutaneous receiver receives the stimulation signal, and the subcutaneous transmitter generates a feedback signal in response to receipt of the stimulation signal by the subcutaneous receiver. The supercutaneous receiver receives the feedback signal. In one variation of the embodiment, the signal processor generates an alarm signal when the feedback signal is not received. In another variation of the embodiment, the signal processor analyzes differences between the stimulation signal and the feedback signal, and generates a difference signal indicative of the differences between the stimulation signal and the feedback signal. The signal processor then generates the alarm signal in the event the difference signal indicates the differences exceed a prescribed threshold.
