Abstract:
1. A system comprising: a current steering management facility configured to set a current steering range for a stimulation channel defined by first and second physical electrodes communicatively coupled to an auditory prosthesis to be less than an entire physical range of the stimulation channel, the current steering range being centered about a midpoint of the stimulation channel; a mapping facility communicatively coupled to the current steering management facility and configured to map each frequency included in a frequency band associated with the stimulation channel to one or more virtual electrodes included in the current steering range of the stimulation channel; and a spectral analysis facility communicatively coupled to the mapping facility and configured to detect a frequency associated with an audio signal and included within the frequency band; wherein the current steering management facility is further configured to wherein a ratio of the first current level to the second current level is based on a position of the identified virtual electrode within the current steering range of the stimulation channel.
