摘要:
According to an embodiment, a bilateral cochlear implant (Cl) is disclosed. The bilateral Cl comprises (i) a first microphone or a first microphone array, positioned at or in the vicinity of a first ear of a user of the bilateral Cl, adapted to receive a sound and to generate a first microphone signal in response to the received sound; (ii) a second microphone or a second microphone array, positioned at or in the vicinity of a second ear of the user of the bilateral Cl, adapted to receive the sound and to generate a second microphone signal in response to the received sound; (iii) a processor comprising (a) a filterbank adapted to filter the first microphone signal into a plurality of band limited first microphone signals and to filter the second microphone signal into a plurality of band limited second microphone signals; (b) a determination unit adapted to determine a major sound based on analysis of the first microphone signal and/ or the second microphone signal and/ or at least one of the plurality of band limited first microphone signals and/ or at least one of the plurality of band limited second microphone signals and to extract direction of arrival of the major sound; and (c) a processing unit adapted to generate a primary pulse pattern based on the determined major sound and to generate a secondary pulse pattern comprising a copy of the primary pulse pattern and a localization information incorporated therein, the localization information being based on the extracted direction of arrival; and (iv) a pulse generator adapted to generate a primary stimulation pulse based on the primary pulse pattern for stimulating an auditory nerve and a secondary stimulation pulse based on the secondary pulse pattern for stimulating another auditory nerve.
