Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Allocation Method

NA

Intervention Model

SINGLE_GROUP

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.

Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

Participants will be blinded as to which noise reduction setting they are listening to during lab visit objective testing only.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental

Participants will be fit with a commercially available hearing aid and tested using various strengths of the noise reduction feature.
