Abstract:
1. A sound processor for generating electrical stimuli in an auditory prosthesis having an electrode array implanted in a cochlea, the sound processor comprising: a microphone; an analog-to-digital converter electronically coupled to the microphone to receive electronic signals from the microphone, wherein the electronic signals are generated in response to a sound signal, and the analog-to-digital converter is adapted to convert the electronic signals into digital samples; a processor electronically coupled to the analog-to-digital converter to receive the digital samples, the processor being adapted to calculate a traveling wave pattern from the digital samples and generate a stimulus pattern from the calculated traveling wave pattern; and an output signal generator in electronic communication with the processor, the output signal generator being adapted to generate a neural excitation signal from the stimulus pattern and output the neural excitation signal to the electrode array such that the electrode array presents the neural excitation signal and stimulates a neural excitation pattern in the cochlea which approximates a spatio-temporal pattern associated with a traveling wave generated on the basilar membrane in a normally-hearing cochlea when stimulated by the sound signal.
