Abstract:
An apparatus for configuring a frequency range to electrode map disposed in a data storage of a cochlear implant prosthesis, the frequency range to electrode map containing frequency range to electrode mapping data, comprising:a) processing means for processing electrode location data, the electrode location data describing the location of at least two electrodes relative to a cochlea, the electrodes being components of an electrode array, the processing means generating characteristic frequency data and being adapted to determine from said characteristic frequency data said frequency range to electrode map to relate a characteristic frequency to each electrode;b) input means for conveying the electrode location data to the processing means;c) interface means for transferring the frequency range to electrode map to the data storage;wherein the processing means generates the characteristic frequency data according to a characteristic frequency model, wherein the characteristic frequency data includes characteristic frequencies of electrodes of the electrode array, the characteristic frequency of an electrode corresponding to the estimated frequency of maximal displacement of the basilar membrane of the cochlea, according to the characteristic frequency model, at the location of said electrode of the electrode array.
