Title:
SYSTEM AND METHOD FOR DINAMICALLY SETTING CURRENTS TO ATTAIN A TARGET EXCITATION FIELD WIDTH IN A COCHLEAR IMPLANT
Document Type and Number:
WIPO Patent Application WO/2014/093036
Kind Code:
A3
Abstract:
An exemplary sound processor (104) 1) identifies a stimulation site within a cochlea of a patient that is to be stimulated in order to represent acoustic content presented to the patient, the stimulation site included within a plurality of stimulation sites associated with a stimulation channel corresponding to a plurality of electrodes, 2) determines a target excitation field width associated with the stimulation channel and 3) dynamically sets, based on the identified stimulation site, an amplitude and a polarity of current to be applied to each electrode included in the plurality of electrodes in order to represent the acoustic content so that an excitation field created by the current has a width that roughly matches the target excitation field width. A system and a corresponding method are also disclosed.
