Abstract: A system and method are described for generating electrode stimulation signals for electrode contacts in a cochlear implant electrode array. An input audio signal is processed to generate band pass channel signals that each represent an associated band of audio frequencies. From each channel signal channel, audio information is extracted including a channel signal envelope reflecting channel signal energy. Initial electrode stimulation pulses are then generated based on the band pass signal envelopes. A gating function is applied to the initial electrode stimulation pulses based on a gating feedback signal characterizing preceding stimulation signals to produce gated electrode stimulation pulses. The gated electrode stimulation pulses are set to the initial electrode stimulation signals when the band pass signal envelopes are greater than the gating feedback signal, and otherwise are set to zero.

Abstract: A signal processing arrangement generates electrode stimulation signals to stimulation contacts in a cochlear implant electrode array. A signal filter bank transforms an input sound signal into band pass signals, which each represent an associated frequency band of audio frequencies. An envelope processing module processes the band pass signals in a sequence of sampling time frames, wherein for each time frame, the processing includes calculating for each band pass signal at least one signal envelope dynamic property that is changing during the time frame. A channel selection module selects one or more of the band pass signals for each time frame based on the dynamic properties to produce the electrode stimulation signals to the stimulation contacts.

Abstract: A method of generating electrode stimulation signals for an implanted electrode array is described. An acoustic audio signal is processed to generate band pass signals which each represent an associated band of audio frequencies. For each band pass signal, fine time structure information is extracted to determine a sequence of phase event signals. For each sequence of phase event signals, when the number of phase event signals reaches a channel pitch rate factor, a signal limiting period without signals is introduced to produce a modified sequence of phase event signals. Each modified sequence of phase event signals is weighted with a channel amplitude value in order to generate a set of electrode stimulation signals for the implanted electrode array.
