A sound processing method for auditory prostheses, such as cochlear implants, which is adapted to improve the perception of loudness by users, and to improve speech perception. The overall contribution of stimuli to simulated loudness is compared with an estimate of acoustic loudness for a normally hearing listener based on the input sound signal. A weighting is applied to the filter channels to emphasise those frequencies which are most important to speech perception for normal hearing listeners when selecting channels as a basis for stimulation.
L'invention concerne un procédé de traitement de sons pour prothèses auditives, par exemple des implants cochléaires, qui est conçu pour améliorer la perception de la force des sons par les utilisateurs, ainsi que la perception de la parole. On compare l'apport global du stimulus à l'intensité sonore simulée à une estimation de l'intensité acoustique pour un auditeur entendant normalement sur la base du signal sonore entré. Une pondération est appliquée aux voies de filtres pour faire ressortir les fréquences les plus importantes pour la perception de la parole par des auditeurs normaux lorsque l'on choisit des voies comme base de la stimulation.
