Learn About the Latest Technology in Hearing Aids: Earlens

Learn about the latest hearing aids, Earlens.

In many cases, conventional hearing aids and cochlear implants can help people hear better. But both of these technologies have limitations. Cochlear implants require surgery and aren’t suitable for some types of hearing loss, and conventional hearing aids can’t handle certain frequencies.

A new hearing aid technology is putting those problems in the past. Marlowe & Marrs in Sarasota, Florida, offer Earlens hearing aids, a breakthrough technology that is helping patients hear in a more natural way without surgery.

How conventional acoustic hearing aids work

The fundamental design of hearing aids hasn’t changed much in decades. A conventional hearing aid picks up sound from the environment, and the sound is then processed to boost the frequencies according to the wearer’s hearing deficiencies. The sound is then converted to acoustic energy and delivered into the ear of the wearer.

A major drawback of this design, particularly for wearers who require lots of amplification, is feedback. Feedback is the high-pitched whistling sound that occurs when amplified sound from the earpiece is captured by the hearing aid and amplified again. This can result in a frustrating acoustic loop. It’s the same principle that causes loud whining in public address systems.

How Earlens technology is different

The Earlens has three main parts. The first part is the processor. This part wraps around your ear like a traditional hearing aid and is connected to a tube that goes in your ear canal. The second part is a special tip that goes on the end of the tube. The third part is a separate, tiny component — called a lens — which is placed further into your ear canal and rests against your eardrum. This custom lens is placed in your ear by an ear, nose and throat doctor.

First, sound enters the microphones in the processor. The processor then delivers the sound through the tube and to the special tip. The tip then converts the sound into a form of light to signal the lens. The lens then vibrates against your eardrum to transmit sound to your nerves and brain. This is much like the way cochlear implants work, but the Earlens requires no surgery.

The Earlens advantages

Because there’s no output of acoustic energy, there’s no risk of conventional feedback. In addition, the frequency limitations of conventional hearing aids are no longer a limit. The Earlens can generate both lower and higher frequencies, resulting in a closer approximation of natural hearing.
