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.

TIME magazine listed the Earlens as one of the best inventions of 2020. See the listing by clicking here.

Information Regarding Hearing Loss and Hearing Loss Prevention

  • Face masks have become a regular part of the Covid-19 pandemic. Unfortunately, face masks can block speech sounds. The following link provides some tips to help maximize the ability to hear when someone is wearing a face mask or covering. Click here for more information.

  • Noise-induced hearing loss happens because of loud noises that damage the inner ear. Listening to music at volumes louder than 85 decibels (dB) for prolonged periods of time will cause permanent hearing loss. For more information about noise-induced hearing loss, click here.

  • hearWHO* is a free app developed by the World Health Organization for mobile devices which allows people to check their hearing regularly. The app is targeted at those who are at risk of hearing loss or who already experience some of the symptoms related to hearing loss. For more information click here.

  • Our National Academy, the American Academy of Otolaryngology-Head and Neck Surgery has recently published a recommendation regarding a cochlear implant for unilateral sensorineural hearing loss (single-sided deafness). For more information regarding a cochlear implant and unilateral sensorineural hearing loss, click here.
