Engineers Developing a Retainer That Could Let the Hearing Impaired Experience Sound With Their Tongue

Researchers at Colorado State University’s Department of Mechanical Engineering are developing a retainer that could circumvent the need for cochlear implants, instead helping people with severe hearing loss experience a restored sense of sound through their tongue. The device works with a Bluetooth earpiece, which sends sound to the retainer that wearers can “hear” by way of their tongue.

When users press their tongue against the device, they feel a distinct pattern of electric impulses as a tingling or vibrating sensation. The idea is that, with training, the brain will learn to interpret specific patterns as words, thus allowing someone to “hear” with their tongue.
