About

The research will produce clinical effectiveness performance metrics using standardised procedures of the Nuance Audio hearing device.

Full description

EssilorLuxottica is actively pursuing commercialization of their Nuance Audio device in the US (Class 2 - OTC SaMD) and in the EU under the Class IIa classification for hearing aids. The device form factor is an eyeglass frame. Currently there are no medical devices marketed as a hearing aid in the intended form factor (Nuance Audio) which suggests the need for preclinical and clinical evaluations to assess any impact to non-clinical standards compliance and user clinical performance. The manufacturer is actively addressing standards compliance with qualified third-party laboratories and has engaged NAL to collaborate on the clinical assessments based on its extensive history and expertise in the personal hearing aid arena.

Clinical assessment of device performance (basic safety and effectiveness with intended users) will be conducted as per study protocol. Additionally, to ensure quality, preliminary bench top compliance testing will be conducted as part of the study prior to first participant enrolled.

Description:

This study uses a within-subjects design in which participants complete assessments in both unaided and aided conditions, using the Nuance Audio Glasses as the investigational hearing aid device. Each participant attends two sessions at the National Acoustic Laboratories (NAL), with testing conducted in controlled and real-world environments. Research methods include: Audiometric assessments: Pure-tone audiometry, tympanometry, and Real Ear Measurements (REMs). Speech perception testing: Conducted in both quiet and noise using validated Australian English BKB sentence materials. Real-world assessments: Moderated walking tour in various acoustic settings (e.g., quiet rooms, traffic noise, multi-talker babble). Self-reported measures: Questionnaires assessing hearing difficulty (HHIE-S), listening goals (COSI), perceived benefit (IOI-HA), and device preference and satisfaction.
