1. In a cochlear stimulator system comprising a wearable processor (wp) and an implantable cochlear stimulator (ICS), and wherein the WP includes a microphone for detecting audio signals, processing means for processing the detected audio signals, and first transceiver means for transmitting and receiving electrical signals to and from the ICS, and further wherein the ICS comprises second transceiver means for receiving and transmitting electrical signals from and to the WP, electrode means for making electrical contact with tissue to be stimulated, means for generating a stimulus signal in response to received electrical signals for application to the electrode means, and back telemetry means for generating telemetry signals for transmission back to the first transceiver means of the WP through the second transceiver means, a method for detecting failures comprising:

  • detecting an audio signal through the microphone;

    generating a stimulation signal in response to the detected audio signal;

    transmitting the stimulation signal to the second transceiver means of the ICS through the first transceiver means of the WP;

    receiving the transmitted stimulation signal at the second transceiver means;

    generating a feedback signal in the event the stimulation signal is received by the second transceiver means;

    transmitting the feedback signal to the first transceiver means of the WP through the second transceiver means of the ICS;

    generating an alarm signal to alert an operator in the event the feedback signal is not received by the second transceiver means.
