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.

Conditions

  • Hearing Loss, Sensorineural

Interventions

DEVICE

Hearing aid

Settings in a wearable hearing aid will be adjusted within a clinically-relevant range for two features. The features include wide dynamic range compression and microphone directionality.
