EssilorLuxottica has announced new clinical findings from two studies evaluating the performance of Nuance Audio Glasses, its all-in-one open-ear hearing solution built into smart eyewear and intended for adults with mild to moderate hearing loss.
The results were presented for the first time in Europe during the 69th EUHA Congress (European Union of Hearing Aid Acousticians) in Hanover, Germany, as part of the official academic programme.
Dr Tami Harel, chief of audiology of Nuance Audio at EssilorLuxottica, presented the session on, ‘Clinical efficacy of open-ear hearing aid glasses’, sharing outcomes from studies conducted at Western University (Canada) and the National Acoustic Laboratories (NAL, Australia).
Collectively, the studies evaluated both controlled laboratory performance and real-world listening experiences.
The Western University study evaluated Nuance Audio Glasses in controlled yet realistic noise conditions, designed to simulate daily listening environments. Results demonstrated: up to 29 per cent improvement in speech understanding in challenging acoustic conditions, and “significant reduction in listening effort, as measured through standardised rating scales”.
The NAL study assessed both laboratory performance and short supervised real-world use. Reported outcomes included a 3.48 dB improvement in signal-to-noise ratio; 70 per cent of participants reported improved communication ability after three hours of real-world use.
Dr Harel said: “One insight stands out across both studies: users prefer to wear Nuance Audio Glasses in the real, noisy conversations that matter most to them. These results mark an important achievement in terms of the post-market clinical validation of the product for early-stage hearing support.”
Stefano Genco, global head of Nuance Audio at EssilorLuxottica, commented: “Presenting these results for the first time at the EUHA Congress confirms our commitment to scientific rigour and innovation. We are proud to advance solutions that are not only clinically proven but also designed to seamlessly improve people’s everyday lives.”
