Abstract:
1. A method comprising: dividing an audio signal presented to a cochlear implant patient into a plurality of analysis channels each containing a frequency domain signal representative of a distinct frequency portion of the audio signal; detecting a maximum energy level of each of the frequency domain signals; identifying, based on the detected maximum energy levels of each of the frequency domain signals, one or more spectral peaks and one or more other spectral components of the audio signal; selectively applying electrical stimulation representative of the one or more spectral peaks to at least one stimulation site within the cochlear implant patient using a partial multipolar stimulation configuration; and selectively applying electrical stimulation representative of the one or more other spectral components of the audio signal to at least one other stimulation site within the cochlear implant patient using a monopolar stimulation configuration; wherein the selectively applying of the electrical stimulation representative of the one or more spectral peaks using the partial multipolar stimulation configuration comprises concurrently
