The Earlens® Contact Hearing Solution directly activates the hearing system, delivering the broadest bandwidth available today and superior sound quality.
The idea for Earlens was born with Dr. Rodney Perkins, a pioneer in the hearing industry. During his experiments to vibrate the eardrum, patients praised the sound quality of what they heard. Across the next 25 years, the team worked to extend the concept into a commercial product. They created a non-surgical method to place a custom Lens stably on the eardrum, developed innovative custom manufacturing techniques, and completed a multi-center clinical trial that proved the device was safe and effective for treating hearing loss.
Acoustic device receivers face fundamental output limitations — particularly in the very low and very high frequencies in the real ear. Only Earlens provides audiometrically proven functional gain from 125 to 10,000 Hz even in a vented condition, with an average of 30-40 dB functional gain at 6,000 Hz and demonstrated audibility through 10,000 Hz. The Earlens Processor captures sound and converts it to an ultra low-power radio signal that carries high-fidelity audio data and powers the Lens. The Lens gently vibrates the eardrum to activate the natural hearing system. All this is achieved with a signal that is less than 1/400th of the power output of a mobile phone.

Earlens, Who is a Candidate and What are the Benefits?

Mandikal Vasuki et al. (2020) used collected double blind sound quality ratings for streamed music and speech content recorded through the Earlens system as well as four other premium acoustic hearing aid technologies. The results confirmed that normal hearing listener rated the sound quality for Earlens significantly higher than the other four technologies for both music and speech samples that were recorded for widely vented (or open dome) fittings. Long term average spectrum analysis of samples affirm that Earlens preserves spectral information that is lost through venting in traditional acoustic hearing aids resulting in higher ratings for sound quality. This provides confirmatory evidence that despite streaming codec being limited to 8kHz, listeners prefer fullness and clarity provided by broad frequency amplification achieved through a direct drive technology such as Earlens.October 26, 2020
Vaisberg et al (2020) gathered ratings of sound quality for multiple conditions of filtered stimuli presented through the wide bandwidth Earlens device. This is an extension of the method and results first shown by Moore & Tan in normal-hearing listeners in 2003, which demonstrated that improved sound quality results from having both extended low and high frequencies present – which were beyond the limits of conventional acoustic hearing aid technology; however in this paper those findings were confirmed in Earlens users with mild-sloping-to-severe sensorineural hearing loss in the as-clinically-fitted condition. This provides confirmatory evidence in the sound quality benefits of extended bandwidth of amplification through an Earlens system – and confirmed suprathreshold audibility that meets or exceeds the claimed range of 125-10,000 Hz for the target population in an independent and reputable research center. One of the most interesting results reported in this paper is that the “pedestal” of low frequency amplification down to 100 Hz is provided to all Earlens users even with a widely vented fitting. This low frequency amplification may be even more important than previously realized in terms of making the high frequencies more acceptable. This seems to be the case even for those with mild low frequency losses who would usually be fit with vented acoustic technology that is unlikely to provide low frequency amplification under these conditions. The result is that Earlens users are more likely to be able to benefit from the information encoded in the high frequencies, because balancing the highs with the lows makes the high frequencies more palatable and overall sound quality more natural.October 26, 2020
