Baseline Performance and Fitting Parameters for Sonova Products

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the effectiveness and optimization of various FDA approved products.

Detailed Description
-----------------
This study uses a prospective within-subjects repeated-measures design in which each subject serves as her/his own control. The purpose of this study is to assess the effectiveness and optimization of various FDA approved hardware, signal preprocessing and processing software, fitting characteristics, and service delivery methods, such as remote support and/or tele-audiology on an expanded subject demographic. The insights gained from this study will be used to optimize listening configuration recommendations, refine audiological practice, and inform future innovations.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Localization performance | A secondary efficacy endpoint is a front/back localization task where filtered pink noise is presented at 60dBA from one of six speakers in a 360 degree array. Scores are generated in percent correct; the scores obtained from the pinna-located microphone will be compared to the localization scores using the pinna-simulated microphone. | 1 day | 
| Analysis of usability and preference questionnaire | Subject responses captured on a usability and preference questionnaire at the initial visit will be compared to responses on the questionnaire administered after each two-week chronic use interval. Questions will inquire about subject's ability and experience hearing and listening in different situations and wearing configuration preferences. The questions are rated on a 5-point Likert scale with varying strength, such as It was easy to verify proper microphone function with answers ranging from strongly disagree to strongly agree. | 8 weeks |
