Comparing Self-Fitting Strategies in the Lexie Powered by Bose Hearing Aids

The intervention offered is a hearing aid fitting with the Lexie B2 Powered by Bose receiver-in-the-canal hearing aids using a self-fitting strategy with direct adjustment. The hearing aids will be accompanied and operated with the Lexie smartphone application. Participants will complete a hearing screening (at 500, 1000, 2000 and 4000 Hz) called Hearing Check on the Lexie smartphone application, which will be used to tune the hearing aids according to frequency and loudness level. Participants will be able to use two wheels to change the loudness and fine-tune the hearing aids. Participants will wear the hearing aids for four weeks.

The intervention offered is a hearing aid fitting with the Lexie B2 Powered by Bose receiver-in-the-canal hearing aids using the in-situ audiometry fitting strategy. The hearing aids will be accompanied and operated with the Lexie smartphone application. Participants will complete an in-situ audiogram on the Lexie app, which enables the measurement of hearing thresholds through the hearing aids (at 500, 1000, 2000 and 4000 Hz). The hearing aids will then be self-programmed according to the participant's in-situ audiogram with a proprietary fitting algorithm that is based on NAL-NL2. Participants will wear the hearing aids for four weeks.
