1. A cochlea stimulation system, comprising:

  • audio signal receiving means, including a headpiece coupled to a signal and energy coupling means, the headpiece having transmitting and receiving means and means for transferring data through the signal and energy coupling means at one frequency for data that originates from an implanted cochlea stimulator (ICS) and is sent to an externally wearable signal processor (WP); and

    at another frequency data and energy originate from the WP and are sent to the ICS;

    said WP receives and processes audio signals received by the audio signal receiving means and includes means for generating data indicative of the audio signal;

    means for transmitting the data to the ICS, the ICS including;

    means for receiving transmissions from the WP,processor means for processing such transmissions to generate stimulation signals,a plurality of electrically isolated capacitor-coupled cochlea stimulating electrodes for receiving the stimulation signals,means in the ICS responsive to data from the WP for selectively monitoring at least one of the electrodes or voltages in the processor and for generating ICS status indicating signals,means in the ICS for transmitting such ICS status indicating signals to the WP; and

    means in the WP for receiving and processing the ICS status indicating signals.
