Abstract:
1. A process for improving hearing perception in a human with an at least partially functional organ of Corti, the process comprising the steps of: by producing pulsed light irradiation in a pulsed light source, controlling and modulating the frequency of the light irradiation, transmitting the modulated pulsed light irradiation to partially functional sections of the organ of Corti through at least one optical fibre coupled to the pulsed light source and receiving the pulsed irradiation, wherein the optical fibre is permanently implanted, and which optical fibres are dimensioned and elastically conformal to a spiral shape for termination in end sections in the very next vicinity but not touching functional inner hair cells of the organ of Corti, wherein the cross-sectional surface of the end section of the optical fibre forms an angle of 10° to 80° from the longitudinal fibre axis, and implanting the optical fibre such that an end section of the optical fibre is disposed in the very next vicinity but not contacting functional inner hair cells of the organ of Corti.
