Abstract

An exemplary system includes a sound processor configured to process one or more audio signals and an implantable cochlear stimulator configured to apply stimulation representative of the one or more audio signals to a patient via a plurality of electrodes. In some embodiments, the sound processor directs the implantable cochlear stimulator to 1) apply a main current to a first electrode included in the plurality of electrodes and associated with a first pitch, 2) concurrently apply, during the application of the main current, a compensation current to a second electrode included in the plurality of electrodes and associated with a second pitch that is lower than the first pitch, and 3) adjust the compensation current to result in a target pitch being presented to the patient, the target pitch being higher than the first pitch.

First claim

What is claimed is:

1. A system comprising:
a sound processor configured to process one or more audio signals; and
an implantable cochlear stimulator communicatively coupled to the sound processor and configured to apply stimulation representative of the one or more audio signals to a patient via a plurality of electrodes;
wherein the sound processor directs the implantable cochlear stimulator to
apply a main current to a first electrode included in the plurality of electrode…
