Study Summary
The goal of this project is to determine whether the selection of hearing aid settings should be based in part on an individual's cognitive characteristics (specifically, working memory). We anticipate the outcomes of this study to be applicable to realistic listening conditions.
Primary Outcome
Listeners will listen to and repeat recorded low-context sentences mixed with noise from different spatial locations. Speech intelligibility will be measured immediately following hearing aid fitting. Scoring is determined by percentage of words repeated correctly. Scores range from 0-100% (higher score indicates better performance). This task may take up to 1-2 visits (\~ 2 hours each) for different combinations of hearing aid features. The device will only be worn in the laboratory for the dur
