What is Hearing loss?
Hearing loss, also known as hard of hearing, anacusis, or hearing impairment, is a partial or total inability to hear. In children hearing problems can affect the ability to learn language and in adults it can cause work related difficulties. --> Deafness is typically used to refer to those with no or only little hearing.
Hearing loss may be caused by a number of factors, including: genetics, old age, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common infection that results in hearing loss is chronic ear infections. Certain infections during pregnancy such as rubella may also cause problems. Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear. Testing for poor hearing is recommended for all newborns. Hearing loss can be categorised as as mild, moderate, severe, or profound.
Half of hearing loss is preventable. This includes by immunization, proper care around pregnancy, avoiding loud noise, and avoiding certain medications. The World Health Organization recommends that young people limit the use of personal audio players to an hour a day in an effort to limit exposure to noise. --> For many hearing aids, sign language, cochlear implants and subtitles are useful. Lip reading is another useful skill many develop. Access to hearing aids; however, is limited in many areas of the world.
Globally hearing loss affects about 10% of the population to some degree. Some within this community view cochlear implants with concern as they have the potential to eliminate their culture. The term hearing impairment is often viewed negatively as it emphasis what people cannot do.
