This guide is intended for Cochlear implant recipients and their ™ ® carers, who use their Cochlear Nucleus 7 Sound Processor in ™ Hybrid mode. People with certain types of hearing loss can wear the processor in Hybrid mode by adding a Hybrid system which sends amplified acoustic sound into the ear canal.
(like a hearing aid). In Hybrid mode, your Nucleus 7 Sound Processor delivers two types of sound signals: • the usual electric signals to the Cochlear implant • extra acoustic signals to the Hybrid system. NUCLEUS® 7 HYBRID™ USER GUIDE...
