Noise Reduction Preferences in Teenagers and Pre-teens

Study Overview
=================
Brief Summary
-----------------
Noise reduction preferences and blue tooth access to hearing aid streaming features will be evaluated in experienced hearing aid users age 10-17.

Detailed Description
-----------------
The purpose of this study is to evaluate the preferences for hearing aid noise reduction settings in users age 10 -17, as well as to evaluate preferences for accessing the hearing aid Bluetooth streaming programs for this population. Subjective preferences will be obtained by having the participants listen to a noisy scene with different levels of noise reduction, to which they are blinded, and rate their preference. Blinded objective speech performance testing will be completed by a) finding the signal-to-noise ratio at which participant can correctly repeat back 50% of the target words, and b) measuring the percent of words correctly repeated during a noisy listening task. These tasks will be done using different levels of noise reduction. Subjective preferences for accessing Bluetooth streaming will also be obtained by asking participants which method they prefer (phone, hearing aid, or touch control). .

Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Interventional Model Description: All participants will be fit with hearing aids with the same noise reduction feature. This feature has distinct, discrete levels of noise reduction which will be evaluated by the participants.
Masking: None (Open Label)

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| verbal response accuracy | percent correct of monosyllabic words presented in noise at different levels of noise reduction, while also performing a visual task | Day 14 of study, visit 2 | 
| verbal response time | length of time it takes participant to respond verbally to monosyllabic words presented in noise at different levels of noise reduction, while also performing a visual task | Day 14 of study, visit 2 | 
| subjective rating of listening effort questionnaire | participant will rate perceived listening effort during a speech in noise task with different levels of noise reduction. Participants will rate how long the task seemed to take using a sliding scale with 100 increments between two verbal anchors: it felt fast to it took forever. Higher scores indicate higher perceived listening effort. | Day 14 of study, visit 2 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| speech reception threshold | signal to noise ratio in which participant can correctly repeat 50% of key words at different levels of noise reduction | Day 28, visit 3 | 
| subjective questionnaire on preference for accessing bluetooth on phone | subjective questionnaire about streaming access preferences. Participants will indicate which method (Hearing aid push button, phone control, or tap control on hearing aid) for answering phone calls and listening to audio streaming on phone. | Day 28, visit 3 | 
| subjective preference questionnaire for hearing aid noise reduction settings | blinded paired comparison between two different settings of noise reduction, while listening to a story presented in noise. Participants will indicate whether they prefer listening to setting A or setting B. Investigator will switch the settings so that participant is not aware of what the settings are. | Day 1 of study, visit 1 |
