(57) Abstract:
(EN): A signal processing arrangement is described for signal processing in a bilateral hearing implant system. A channel compression module develops a inhibition-adjusted band pass signal for each band pass signal using a channel-specific dynamic inhibition adjustment based on a channel-normalized medial olivocochlear reflex model that reflects bandwidth energy for a corresponding contralateral band pass signal and bandwidth energy for a selected reference contralateral band pass signal.
(FR): La présente invention concerne un agencement de traitement de signal pour un traitement de signal dans un système d'implant auditif bilatéral. Un module de compression de canal développe un signal passe-bande ajusté par inhibition pour chaque signal passe-bande utilisant un ajustement d'inhibition dynamique spécifique au canal sur la base d'un modèle de réflexe olivo-cochléaire médial normalisé selon le canal qui reflète l'énergie de bande passante pour un signal de passe-bande controlatéral correspondant et une énergie de bande passante pour un signal passe-bande controlatéral de référence sélectionné.
