Outcome Measures

Primary Outcomes (1)

  • Speech performance in noise

    The primary efficacy endpoint is recorded AzBio sentences presented from a single loud speaker at 60 dBA. The recognition scores using the pinna-located microphone in quiet and noise captured at initial visit will be compared to the AzBio sentence recognition scores using the pinna-simulated microphone. Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome.

    1 day

Secondary Outcomes (2)

  • Localization performance

    1 day

  • Analysis of usability and preference questionnaire

    8 weeks
