A New Hearing Aid Solution: Earlens

Stacks Image 435

Earlens Sound Processor (Left) and Lens (Right)

We are proud to be a provider of Earlens, the world’s first and only hearing solution to directly vibrate the eardrum without surgery. Earlens delivers more complete sound than any traditional, acoustic hearing aid. The more complete sound comes from the Earlens ability to pick up and transmit a broader range of sounds than an acoustic hearing aid. The broader range of sound is associated with a more natural sound quality and better hearing in noise.
In Earlens, a Processor worn behind the ear sends an audio signal through the Ear Tip to a custom Lens that rests directly on the eardrum. When the eardrum receives the signal, it gently vibrates the eardrum to activate the ear’s natural hearing system.
For more information regarding Earlens, click here.
TIME magazine listed the Earlens as one of the best inventions of 2020. See the listing by clicking here.
Forbes Health recently reviewed the Earlens hearing system. For the full report, click here.
