Study 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.
Primary Outcome
The WIN consists of two lists of 35 Northwestern University Auditory Test No. 6 words (NU-6; Tillman and Carhart, 1966) presented in a 6-talker babble at 7 SNRs ranging from 24- to 0-dB in 4-dB decrements. Thus for each list, five unique words spoken by a female talker are presented at each SNR with the level of the babble fixed (Department of Veterans Affairs, 2006). The SNR at which the 50% point occurs is calculated with the Spearman-Kärber equation (Finney, 1952). Normal performance on the W
