Abstract
Disclosed is a method of selecting stimulations for a cochlear implant or an auditory implant. The method may include: capturing an acoustical signal; dividing the acoustical signal into a plurality of frequency bands; determining a mean acoustical energy for each frequency band; for each frequency band: comparing the mean acoustical energy with the mean acoustical energy determined for neighboring frequency bands; merging neighboring frequency bands having a difference between the mean acoustical energies that is less than an acoustical energy threshold value; selecting one or more types of stimulation to be applied to one or more locations in a cochlea or along an auditory nerve based on bandwidths of each frequency band. The one or more types of stimulation may be selected from: electrical stimulation, optical stimulation and opto-electrical stimulation, and the one or more locations in cochlea or along the auditory nerve may correspond to specific frequencies of the acoustical signal.
