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.

Description

[0001] Statement of Government Rights and Interests [0002] This invention was made with United States Government support under Grant No. R01DC011855 awarded by the USA National Institutes of Health. The US Government has certain rights in this invention. technical field [0003] The present invention relates to neural stimulation in cochlear implants. More specifically, the present invention relates to systems and methods for selecting neural stimulation for cochlear implants. Background technique [0004] A cochlear implant (CI) is a surgically implanted neuroprosthetic device that provides sound sensation to persons with moderate to profound sensorineural hearing loss. Commercially available CIs include a series of electrical contacts (electrodes) that can be surgically inserted into the cochlea (tympanic membrane) to stimulate the cochlear nerve. Most commercially available CIs include 12-22 electrical contacts. The contact position of each electrical contact along ...
