Sound Processing Innovations in Adult and Paediatric Cochlear Implant Recipients.

This is a feasibility, prospective with sequential enrolment, multicenter, clinical investigation in adults and paediatrics with a CE approved Nucleus cochlear implant. Subjects older than 5 years will be included. Subjects will be screened and up to 120 eligible subjects will be recruited in the clinical investigation. Subjects will attend scheduled study visits over a period up to 5 years in different sub-studies as described in the sub-study documentation. A clinical setting can consist of therapeutic elements and evaluations. Subjects will be assessed with the commercially available Nucleus sound processor or via the xPC, NIC, etc. if required. Acute testing will be done where possible. Take home use will be applied when learning effects may play a significant role and to evaluate the acceptance of the new or improved sound coding algorithm or signal processing, in as many listening environments as possible. The subject might also be asked to complete questionnaires, to perform at-home tests etc. during this take home use and/or at the clinical visits. The time for a clinical visit will be limited to a maximum of 4 hours. The time in between clinical visits will vary with typical spacing of between 0 (acute) to 4 weeks. The goals of this umbrella investigation are to measure hearing outcomes to assess performance and/or to achieve higher convenience for implant users and hearing care professionals. The outcomes of the study will guide Cochlear to select features for inclusion in future Nucleus cochlear implant systems and/or future models of care.
