Overview
Brief Summary
A feasibility, prospective, multi-centre, repeated measures investigation evaluating the application of hearing aid technologies to signal processing for adult cochlear implant recipients
Detailed Description
The Research System is comprised of several components: the processing unit, fitting software and accessories. The sound processor converts sounds into electrical signals, which it sends, via a coil, to an implant to provide hearing sensation. The application of hearing aid technologies to Cochlear Implant recipients may provide benefit through matching the signal processing technologies across ears for bimodal listeners, enhance performance for CI-alone listening, and potentially lead to efficiency in algorithm development.

Outcomes
Primary Outcomes
Adaptive sentence in noise scores (AuSTIN)
Time Frame: 3 months
To determine whether the research system provides non-inferior performance to the Nucleus 8 sound processor for sentences in noise.
Percent correct monosyllabic word scores.
Time Frame: 3 months
To determine whether the research system provides non-inferior performance to the Nucleus 8 sound processor for monosyllabic words in quiet CNC words at 60 dB SPL (sound pressure level) Word recognition is a score of the number of words correctly repeated, expressed as a percentage. Higher percentage scores indicate a better outcome.
