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.

eyewear frames embedded with groundbreaking technology which seamlessly integrate an air conduction hearing aid (over-the-counter "OTC", in the United States) intended to amplify sound for adult users (18yrs and older) with a perceived mild to moderate hearing impairment. Nuance Audio Glasses may, if necessary, be used in association with prescription lenses for those adults who also require correction of visual defects. Nuance Audio Glasses can be worn all day and can be easily configured via the App to adapt to any situation, from business meetings to family time.

Moderated walking tour in various acoustic settings (e.g., quiet rooms, traffic noise, multi-talker babble).

Questionnaires assessing hearing difficulty (HHIE-S). The outcome measure is the grade of 10 questions ( 0 - 2 or 4 points per each question).

Questionnaires assessing listening goals (COSI). The outcome measure is the grade in 5 different situation for entity of benefit ( on a scale from 1 to 5) and frequency of the benefit ( on a scale form 1 to 5)
