Title
(EN) METHODS AND SYSTEMS FOR LOWERING A PITCH SENSATION AS PERCEIVED BY A COCHLEAR IMPLANT PATIENT
(FR) PROCÉDÉS ET SYSTÈMES POUR RÉDUIRE UNE SENSATION DE HAUTEUR TONALE TELLE QUE PERÇUE PAR UN PATIENT AYANT UN IMPLANT COCHLÉAIRE
Abstract
(EN)
An exemplary method of lowering a pitch sensation as perceived by a cochlear implant patient includes 1) identifying a most apical electrode included in a plurality of electrodes disposed within a cochlea of the patient, 2) directing a cochlear implant communicatively coupled to the plurality of electrodes to apply one or more anodecathode biphasic stimulation pulses to the most apical electrode during a stimulation period, and 3) directing the cochlear implant to apply one or more cathode-anode biphasic stimulation pulses to one or more other electrodes included in the plurality of electrodes during the stimulation period. Corresponding methods and systems are also disclosed.
(FR)
L'invention concerne un procédé à titre d'exemple pour réduire une sensation de hauteur tonale telle que perçue par un patient ayant un implant cochléaire, lequel procédé à titre d'exemple consiste 1) à identifier une électrode la plus apicale incluse dans une pluralité d'électrodes disposées à l'intérieur d'une cochlée du patient, 2) à diriger un implant cochléaire couplé en communication à la pluralité d'électrodes pour appliquer une ou plusieurs impulsions de stimulation biphasiques anode-cathode à l'électrode la plus apicale durant une période de stimulation, et 3) à diriger l'implant cochléaire pour appliquer une ou plusieurs impulsions de stimulation biphasiques cathode-anode à une ou plusieurs autres électrodes incluses dans la pluralité d'électrodes durant la période de stimulation. L'invention concerne également des procédés et des systèmes correspondants.
