Clinical Validation of the Lexie Lumen Hearing Aid

The intervention offered is a hearing aid fitting with Lexie Lumen hearing aids coupled with a slimtube and dome. The hearing aids will be accompanied and operated using the Lexie smartphone application. Participants will self-perform an in-situ hearing check (pure tones presented via the hearing aids). The prescriptive gain of the hearing aids will be programmed and applied automatically using the obtained in-situ hearing thresholds. Participants will be fitted according to the customized, Lexie optimal fit prescribed gain setting. The optimal settings include the original gain and compression requirements that NAL-NL2 suggests for various audiograms. No additional band equalizer or compression adjustments are added. After a specified period of time, participants will be able to self-adjust the hearing aids using the smartphone application.
