| 发明名称 | Compensation current optimization for cochlear implant systems | ||
| 摘要 | An exemplary method includes 1) applying a main current to a first electrode disposed within a patient and associated with a first pitch, 2) concurrently applying a compensation current to a second electrode disposed within the patient and associated with a second pitch during the application of the main current, the compensation current being out-of-phase with the main current, and 3) optimizing an amount of the compensation current to result in a target pitch being presented to the patient that is distanced from the first pitch in a pitch direction opposite a pitch direction of the second pitch in relation to the first pitch. Corresponding methods and systems are also disclosed. | ||

| 主权项 | 1. A method comprising: directing, by a sound processor, an implantable cochlear stimulator to apply a main current to a first electrode disposed within a patient and associated with a first pitch; directing, by the sound processor, the implantable cochlear stimulator to concurrently apply, during the application of the main current, a compensation current to a second electrode disposed within the patient and associated with a second pitch that is lower than the first pitch; and directing, by the sound processor, the implantable cochlear stimulator to adjust the compensation current to result in a target pitch being presented to the patient, the target pitch being higher than the first pitch. | ||
