简要总结

The cochlear implant provides good auditory performance despite high inter-individual variability, but performance in noise remains limited. Modification of the coding strategies could improve these performances. A better characterization of the remaining neuronal population by looking for the charge integration efficiency (which depends on the duration and the amplitude of the electrical pulse) would allow an optimization of the settings by adapting either the duration or the amplitude of the pulse according to the quality of the remaining neuronal population.

详细描述

The cochlear implant provides good auditory performance despite high inter-individual variability, but performance in noise remains limited. Modification of the coding strategies could improve these performances. Currently, the intensity perceived by the patient is coded by the duration and the amplitude of the electrical impulse but companies have different approaches and fix one of the two parameters for the setting of the processors. A better characterization of the remaining neuronal population by looking for the charge integration efficiency (which depends on the duration and the amplitude of the electrical pulse) would allow an optimization of the settings by adapting either the duration or the amplitude of the pulse according to the quality of the remaining neuronal population.
