Clinical studies have confirmed functional audibility of speech sounds achieved with the Earlens Contact Hearing Solution through 10 kHz while functional audibility is limited to ~5 kHz with conventional acoustic amplification (Struck and Prusick, 20171; McElveen et al., COSM, 20172; Arbogast et al., 20183). Preference data is positive for the sound quality of the broad spectrum amplification provided by the Earlens Contact Hearing Solution over participant’s prior acoustic aids in multiple listening categories including listening in noise, music, and group conversations (Arbogast et al., 20183).
The Earlens Contact Hearing Solution’s unique mechanism of action allows for the provision of low-frequency output for streamed sources while maintaining a widely vented fitting. Using the Multiple Stimuli with Hidden Reference and Anchor (MUSHRA) industry-wide standard method for evaluation of sound quality, subjective judgments of streamed audio quality of the Earlens compared with open-fit MFi-capable acoustic hearing aids revealed that Earlens offers the best streamed audio sound quality for speech and music in subjects with normal and impaired hearing (Eskridge et al., AAA 20196).
Fay et al. (2013) published initial Earlens clinical results demonstrating safety, technical feasibility, and patient improvement of direct-drive technology. Gantz et al. (2016) demonstrated hearing stability was maintained after lens wear. Earlens continues monitoring device safety.
“This is the only technology that I offer where patients routinely cry tears of joy when we activate them. So it's very gratifying for me to be able to offer something like this to my patients.”
“Earlens allows patients to get the best possible return in their investment for their hearing health. They're going to get the best devices, recurrent efforts to make their devices maximize their performance and that results in better outcomes that my patients are thrilled with.”
“Earlens has changed my world for the better.”
Earlens is designed to restore more of the natural range of audibility than any acoustic hearing aid
