简要总结
Noise reduction preferences and blue tooth access to hearing aid streaming features will be evaluated in experienced hearing aid users age 10-17.
详细描述
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).

结局指标
主要结局
Subjective Rating of Listening Effort Questionnaire
时间窗: Day 14 of study, visit 2
Participant will rate perceived listening effort during a speech in noise task with different levels of noise reduction. Participants will rate how easy the task seemed using a sliding scale with 100 increments between two verbal anchors: "it was very easy" to "it was not easy at all". Higher scores indicate higher perceived listening effort. A rating of "0" would indicate "it was very easy" to understand the speech while a rating of "100" would indicate "it was not easy at all" to understand the speech.
