摘要：
The invention provides a cochlea stimulator for implantation comprising optical fibres of which are coupled to an irradiation source that is controlled by a modulator to generate irradiation specific for a pre-determined range of sound- frequencies. The cochlea stimulator effects a frequency-specific activation of the organ of Corti needed for speech perception especially in noisy environment and more complex sounds. For imparting excitation signals which are generated by modulated irradiation conducted within an optical fibre in order to elicit nervous signals in residual functional organ of Corti sections, the auditory prosthesis preferably contains optical fibres which are dimensioned to terminate in end sections within the cochlea at different sites or sections of the organ of Corti, e.g. having different lengths for locating their end sections at different internal parts of the cochlea.
