HARMONIC ALLOCATION OF COCHLEA IMPLANT FREQUENCIES

An aspect of the disclosure is to provide a system and a method of fitting a cochlea implant system to a patient, the method comprising determining an insertion angle of at least one electrode of a first electrode array of the cochlea implant system inserted into a cochlea of the patient, determining a plurality of natural frequencies as a function of a cochlea spiral length based on a natural frequency allocation model and the insertion angle, determining a plurality of characteristic frequencies as a function of a cochlea spiral length by frequency downshifting the plurality of natural frequencies until an objective is obtained and while preserving the harmonic relationship between the natural frequencies of the plurality of natural frequencies in the plurality of characteristic frequencies, and allocating the plurality of characteristic frequencies to each electrode of the first electrode array based on the insertion angle of the at least one electrode.
