ABSTRACT:
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.
