Glasses that hear: new device aims to help people with hearing loss
NCT ID NCT07074769
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested a hearing aid that is built into a pair of glasses for adults with mild to moderate hearing loss. The goal was to see if the device helps people understand speech better in noisy settings and reduces listening effort. Twenty-one adults participated in a lab setting, comparing their hearing with and without the device using speech tests and a questionnaire.
