MENLO PARK, Calif., May 13, 2021 A landmark study conducted by the world-renowned audiology team at The National Centre for Audiology at Western University in Ontario, Canada was just published in Trends in Hearing.
A landmark study supported the value of restoring audibility across an extended bandwidth in hearing aid fittings.
The peer-reviewed study evaluated the benefit of the extended bandwidth of the Earlens direct contact hearing technology and found that the broader range of sound proved superior in all outcome measures, demonstrating clinically meaningful benefits for patients. Those benefits included the ability to:
Better understand sentences in situations with louder background noise
More accurately recognize consonant sounds that are critical for distinguishing words
Not surprisingly, patient satisfaction also proved in favor of Earlens, with the majority of patients preferring the fuller bandwidth over the narrower bandwidth associated with their acoustic hearing aids.
Dr. Drew Dundas, a co-author of the paper said: “The findings reinforce the importance of an extended bandwidth in delivering what people with hearing impairment have been requesting for years—better hearing in challenging environments. Hearing aid wearers often complain that they can hear speech but can’t understand it. That is why Earlens is such a game-changing technology. By directly vibrating the eardrum, Earlens accomplishes what traditional hearing aid manufacturers have attempted to achieve through complex algorithms, which will always be constrained by the limitations of physics.”
Based on the hearing benefits observed, the authors conclude that the findings support the value of restoring audibility across an extended bandwidth in hearing aid fittings for patients with mild-to-severe sensorineural hearing loss.*
