Early Feasibility, Exploratory, Within-subject, Acute Study Comparing the Performance of Different Sound Paths in Adult NeuroZti CI-users
The goal of this clinical trial is to compare speech perception and user satisfaction between two sound paths, Nuc8 (Cochlear Nucleus sound path) and Neu2 (Neuro 2 sound path), in adult users of the NeuroZti cochlear implant. Following Cochlear's acquisition of Neurelec, there is a need to support existing NeuroZti implant users who currently rely on the Neuro 2 sound processor. The Nuc8-based sound processor, currently in development, is designed to be compatible with the Neuro system while integrating with Cochlear's ecosystem of tools and applications developed over the past decade. To ensure long-term support and maintainability, transitioning to the Nuc8 sound path is preferred. However, changes in sound paths may impact sound quality, speech perception, and user acceptance. The main question this study aims to answer is: how does speech performance and user satisfaction compare between the Nuc8 and Neu2 sound paths? Participants will: * Undergo speech perception testing in quiet environments * Provide ratings on comfort and overall satisfaction The study involves a single visit lasting approximately 3 hours.
• Aged 18-75 years old at time of consent.
• Post-lingually deafened.
• Bilaterally or unilaterally implanted with Oticon Medical Neuro ZTI cochlear implant, using Crystalis with autoXDP (GMCI 'CAP') as the main program, at 500pps stimulation rate. For bilateral CI users, only first-implanted side will be tested.
• Fluent in French as determined by the investigator.
• Willing to participate and comply with requirements of the protocol
• Willing and able to provide written informed consent.
