Hearing impairment
Hearing Impairment
Hearing impairment or hearing loss is a partial or total inability to hear. It may occur in one or both ears. In children, hearing problems can affect the ability to learn spoken language, and in adults, it can cause work-related difficulties.
Pronunciation
Hearing Impairment: /ˈhɪərɪŋ ɪmˈpeər.mənt/
Etymology
The term "hearing impairment" is derived from the Old English hīeran (to hear) and Latin impedire (to hinder).
Causes
Hearing impairment can be caused by many different factors, including genetic disorders, birth defects, exposure to loud noise, certain infections, aging, and certain medications or toxins.
Types
There are three main types of hearing loss: conductive hearing loss, sensorineural hearing loss, and mixed hearing loss.
Diagnosis
Diagnosis of hearing impairment often involves a physical examination, a medical history, and audiometry.
Treatment
Treatment depends on the specific cause if known as well as the extent, type, and configuration of the hearing loss. Most hearing loss, that due to age and noise, is progressive and irreversible, and there are currently no approved or recommended treatments. A few specific kinds of hearing loss are treatable. For example, hearing loss secondary to earwax can be treated with ear irrigation.
