Study Overview
Brief Summary
This is a prospective within-subjects repeated-measures study that will enroll 24 adult users implanted with a HiResolution Bionic Ear System (HiRes 90K or newer). Subjects will be assigned to one of two cohorts based on audiometric results at the Baseline visit
Detailed Description
The overall goal of this clinical study is to demonstrate the safety and efficacy of a cochlear implant sound processor. Hearing outcomes are expected to be similar non-inferior to as compared to the currently approved software and processors. Therefore, the study described herein uses a non-inferiority design to determine whether sentence recognition in quiet and in noise is no worse with the new sound processor than with currently approved software on a Q90 processor.

Outcomes
Primary Outcomes
Speech Recognition in Quiet
Time Frame: 1 Day
The primary efficacy endpoints are AzBio sentence recognition scores in quiet at Baseline with the new sound processor as compared to AzBio sentence recognition scores in quiet at Baseline with currently approved software on a Q90 processor. Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome.
Secondary Outcomes
- Speech Recognition in Noise(1 Day)
- Increased Speech Recognition in Noise(1 Day)
