The present invention provides a cochlear stimulation system and method
for capturing and translating FTS in incoming sounds and delivering this
information spatially to the cochlea. An embodiment of the system may
comprise an FTS estimator/analyzer and a current navigator. An embodiment
of the method of the invention can comprise: analyzing the incoming
sounds within a time frequency band, extracting the slowly varying
frequency components and estimating the FTS to obtain a more precise
dominant FTS component within a frequency band. After adding the fine
structure to the carrier to identify a precise dominant FTS component in
each frequency band (or stimulation channel), a stimulation current is
steered to the precise spatial location on the cochlea that corresponds
to the dominant FTS component, the steering accomplished by delivering
non-simultaneous stimuli through at least two electrodes.
