In this paper, we present an analog integrated circuit containing a matched pair of silicon
cochleae and an address event interface. Each section of the cochlea, modeled by a second-
order low-pass filter, is followed by a simplified inner hair cell circuit and a spiking neuron
circuit. When the neuron spikes, an address event is generated on the asynchronous data
bus. We present the results of the chip characterization and the results of an interaural time
difference based sound localization experiment using the address event representation …

Measurements with pure tones played from different positions are presented.
