The auditory prosthesis comprises n electrodes (e1-en) intended to be implanted in the cochlea at n different points, chosen to allow identification by the brain of a number of different frequency bands within the received sound spectrum. A microphone (6) is connected to a circuit (7,9) for measuring the instantaneous energy of the sound signal in theses frequency bands. Further circuits (3,4,15) control the electrodes cyclically as a function of the energy measured in these respective frequency bands. The time distribution within the sound signal of the energy within these frequency bands is determined (9) such that a transform is applied to the wavelets of the sound spectrum to the processing circuits. The electrodes are then excited in each cycle in the order corresponding to the time distribution. |
