Abstract
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.
Claims20
A method comprising:
- applying a main current to a first electrode disposed within a patient and associated with a first pitch;
- 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
- 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.
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 a compensation current to a second electrode disposed within a 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
- optimizing, by the sound processor, 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.
A programming device comprising:
- a communication interface configured to facilitate communication between the programming device and a cochlear implant system;
- and
- a processor communicatively coupled to the communication interface and configured to
- direct, by way of the communication interface, the cochlear implant system to apply a main current to a first electrode disposed within a patient and associated with a first pitch,
- direct, by way of the communication interface, the cochlear implant system to concurrently apply a compensation current to a second electrode disposed within a 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
- optimize 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.
