Abstract
The invention relates to a method for generating a control signal for a cochlea implant based on an audio signal, comprising a calculation (110) of first information on an activity pattern over time of a number of internal hair cells of an auditive model, arising from the audio signal. The method further comprises a filtering (120) of activity events described by the first information based on a recognition of a characteristic pattern in the activity pattern to give corrected information. The corrected information is then used as control signal for the cochlea implant, or the control signal is derived from the corrected information. Said method can be carried out by a computer programme or a corresponding device. By means of the above, for example, the auditive impression for patients with a cochlea implant can be significantly improved. A filtering of activity events, based on the recognition of a characteristic pattern in the activity pattern is particularly suitable to human hearing and permits the control of a cochlea implant such that the best possible speech recognition with the least possible energy use of a cochlea implant is achieved.
