Abstract:
1. A method of generating a control signal for a cochlear implant, based on an audio signal, comprising: calculating first information describing an activity pattern over time at a plurality of inner hair cells of an auditory model, which is yielded based on the audio signal; filtering out activity events described by the first information based on a recognition of a characteristic pattern in the activity pattern, for achieving, from the first information, cleared information by eliminating activity events pertaining to a characteristic pattern or by eliminating activity events not pertaining to a characteristic pattern, wherein the recognition of a characteristic pattern comprises recognizing a line-shaped curve in a representation of the activity pattern over time and over an index of the inner hair cells as a characteristic pattern; and using the cleared information as a control signal for a cochlear implant, or deriving a control signal for a cochlear implant from the cleared information.
