Question

Briefly explain total hearing impairment.

Answer 1

Hearing loss, also known as hearing impairment, is a partial or total inability tohear.[5] A deaf person has little to no hearing.[2] Hearing loss may occur in one or both ears.[2] In children, hearing problems can affect the ability to learn spoken language and in adults it can create difficulties with social interaction and at work.[6] In some people, particularly older people, hearing loss can result in loneliness.[2] Hearing loss can be temporary or permanent.

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.[2] A common condition that results in hearing loss is chronic ear infections.[2]Certain infections during pregnancy, such assyphilis and rubella, may also cause hearing loss in the child.[2] Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear.[2] Testing for poor hearing is recommended for all newborns.[6] Hearing loss can be categorized as mild (25 to 40 dB), moderate (41 to 55 dB), moderate-severe (56 to 70 dB), severe (71 to 90 dB), or profound (greater than 90 dB).[2] There are three main types of hearing loss: conductive hearing loss,sensorineural hearing loss, and mixed hearing loss.[3]

About half of hearing loss globally is preventable through public health measures.[2] Such practices includeimmunization, proper care around pregnancy, avoiding loud noise, and avoiding certain medications.[2] The World Health Organizationrecommends that young people limit the use of personal audio players to an hour a day in an effort to limit exposure to noise.[7] Early identification and support are particularly important in children.[2] For many hearing aids, sign language, cochlear implants andsubtitles are useful.[2] Lip reading is another useful skill some develop.[2] Access to hearing aids, however, is limited in many areas of the world.[2]

As of 2013 hearing loss affects about 1.1 billion people to some degree.[8] It causes disability in 5% (360 to 538 million) and moderate to severe disability in 124 million people.[2][9][10] Of those with moderate to severe disability 108 million live in low and middle income countries.[9] Of those with hearing loss, it began during childhood for 65 million.[11] Those who use sign language and are members of Deaf culture see themselves as having a difference rather than an illness.[12] Most members of Deaf culture oppose attempts to cure deafness[13][14][15]and some within this community view cochlear implants with concern as they have the potential to eliminate their culture.[16] The term hearing impairment is often viewed negatively as it emphasises what people cannot do.[12]
