METHODS AND SYSTEMS FOR ENHANCING PITCH ASSOCIATED WITH AN AUDIO SIGNAL PRESENTED TO A COCHLEAR IMPLANT PATIENT

摘要

An exemplary sound processor 1) identifies at least one frequency bin, included in a plurality of frequency bins included in a frequency spectrum of an audio signal that is presented to a cochlear implant patient, that contains spectral energy above a modified spectral envelope, 2) identifies each frequency bin that contains spectral energy below the modified spectral envelope, 3) enhances the spectral energy contained in the at least one frequency bin identified as containing spectral energy above the modified spectral envelope, and 4) compresses the spectral energy contained in each frequency bin identified as containing spectral energy below the modified spectral envelope.

1. A system comprising:
a sound processor that
identifies at least one frequency bin, included in a plurality of frequency bins included in a frequency spectrum of an audio signal that is presented to a cochlear implant patient, that contains spectral energy above a modified spectral envelope of the frequency spectrum of the audio signal,identifies each frequency bin included in the plurality of frequency bins that contains spectral energy below the modified spectral envelope,enhances the spectral energy contained in the at least one frequency bin identified as containing spectral energy above the modified spectral envelope by applying a positive gain to the spectral energy contained in the at least one frequency bin identified as containing spectral energy above the modified spectral envelope, andcompresses the spectral energy contained in each frequency bin identified as containing spectral energy below the modified spectral envelope by applying a negative gain to the spectral energy contained in each frequency bin identified as containing spectral energy below the modified spectral envelope.
