Abstract
We present measured frequency-gain functions and the spike rate outputs of the different sections in a spiking silicon cochlea chip. The chip consists of a matched pair of silicon cochleae with an address event interface for the output. Each section of the cochlea is modelled by a second-order low-pass filter 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. These spike outputs are analogous to the spikes on an auditory nerve, connecting the cochlea with the brain.
