Digital Hearing Aid and Cochlear Implant

Approximately 70 million individuals worldwide suffer from hearing loss, which makes it the most common sensory disorder in the world [1–3]. There are estimated 28 million individuals with hearing loss in the United States. Hearing loss affects 17 in 1,000 children under the age of 18, with the incidence increasing with age. Approximately 314 in 1,000 people over the age of 65 have hearing loss, and 40–50% of people 75 and older have hearing loss.
