A novel approach to hearing amplification: audiometric outcomes from Nuance Audio over-the-counter hearing aid glasses

Objective: To evaluate the first audiometric outcomes of Nuance Audio hearing glasses, an over-the-counter solution integrating air conduction amplification technology into standard eyeglass frames, in individuals with mild to moderate hearing loss. Methods: Thirty-two adults (mean age 74 years) with symmetric, age-related mild to moderate sensorineural hearing loss were tested. Pure-tone and speech audiometry were performed under unaided and aided free-field conditions. Device settings were adjusted via smartphone app based on audiometric profiles and user preference. Paired t-tests assessed the differences. Results: Nuance Audio glasses significantly improved hearing thresholds, especially at 4000-6000 Hz, with mean gains of 10-11 dB HL. Speech reception thresholds improved by 7 dB at 50% intelligibility and 6 dB at 100%. Amplification profile preferences matched audiometric slopes and no differences in benefit were found between mild and moderate hearing loss groups. Conclusions: Nuance Audio glasses provide clinically relevant improvements in pure-tone and speech thresholds for adults with mild to moderate presbycusis. Their discreet, open-ear design and self-fitting approach address barriers to traditional hearing aids and may support earlier adoption.
