Deaf people are typically defined as those who have profound hearing impairment in both ears as a result of either acquired or congenital hearing loss. Such people may be associated with deaf culture. Deafness (little to no hearing) is distinguished from partial hearing loss or damage (such as tinnitus), which is less severe impairment in one or both sides. The definition of deafness varies across countries, cultures, and time, though the World Health Organization classes profound hearing loss as the failure to hear a sound of 90 decibels or louder in a hearing test. In addition to those with profound hearing loss, people without profound hearing loss may also identify as deaf, often where the person was raised within a deaf community and for whom sign language is their first language.

Hearing Impairment
Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness. Deaf people usually have little to no hearing. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy, such as cytomegalovirus, syphilis and rubella, may also cause hearing loss in the child. ...
