Claims

1. ELECTRICAL APPARATUS FOR SIMULATING THE COCHLEA, WHICH APPARATUS COMPRISES MEANS RESPONSIVE TO ACOUSTIC SIGNALS FOR SEPARATING SUCH SIGNALS INTO A PLURALITY OF OUTPUT SIGNALS REPRESENTING SUCCESSIVELY SMALLER PORTIONS OF THE ACOUSTIC SPECTRUM, FIRST AND SECOND PLURALITIES OF ELECTRICAL CIRCUIT NEURONS, MEANS RESPONSIVE TO DIFFERENT ONES OF SAID PLURALITY OF OUTPUT SIGNALS FOR SEPARATELY EXCITING EACH OF SAID FIRST PLURALITY OF SAID NEURONS TO PROVIDE NEURON OUTPUT SIGNALS THEREFROM, AND MEANS RESPONSIVE TO THOSE OF SAID NEURON OUTPUT SIGNALS FROM DIFFERENT PAIRS OF SAID FIRST PLURALITY OF NEURONS FOR, RESPECTIVELY, EXCITING AND INHIBITING INDIVIDUAL ONES OF A SECOND PLURALITY OF SAID NEURONS, EACH OF SAID SECOND PLURALITY OF NEURONS PROVIDING OUTPUT SIGNALS REPRESENTING DIFFERENT FREQUENCY COMPONENTS OF SAID ACOUSTIC SIGNALS.
