FIG. 1.

Section diagram consisting of a Hopf amplifier and two sixth-order Butterworth filters. To form the cochlea, the sections are connected in series. A microphone followed by a Hilbert transform is placed at the beginning of the cascade.

(Color) (a, b) Steady-state response (upper panels) and gain (lower panels) for Hopf parameters , . Central frequency: . (c) Physiological measurements (Ref. 9). The device’s response is closer to the electrophysiological response than previous modeling results (Refs. 6, 10, and 11).

Image of FIG. 3.
FIG. 3.

(Color) Salient nonlinear phenomena of hearing: (a) Combination tone, (b) two-tone suppression. Left: electronic cochlea (, central frequency of ), right: physiological measurements (Refs. 13 and 14). The results also closely match with the theoretical predictions (Ref. 15).

Image of FIG. 4.
FIG. 4.

Response to broadband transient stimulation (clicks): (a) hardware (, central frequency of ), (b) physiological measurments (chinchilla, , from Ref. 16).
