Hearing impairment

A hearing impairment is a decrease in one's ability to hear (i.e. perceive auditory information).

While some cases of hearing loss are reversible with medical treatment, many lead to a permanent disability (often called deafness).

If the hearing loss occurs at a young age, it may interfere with the acquisition of spoken language and social development.

Hearing aids and cochlear implants may alleviate some of the problems caused by hearing impairment, but are often insufficient.
