Primary outcomePrimary: Words-in-noise Test — 12.6 dB S/N
Summary
The primary complaint of individuals with hearing loss is difficulty understanding speech in the presence of background noise. Although hearing aids help individuals understand speech in background noise better, there is a high rate of hearing aid rejection in part due to continued difficulty understanding speech in complex listening situations. The results of this study may demonstrate that speech-in-noise test results can be a predictor of hearing aid success. The results of this study also may lead to further studies that can evaluate interventions to improve hearing aid success for individuals who are identified as unsuccessful hearing aid users.
