Hearing loss, also called hearing impairment, is when you do not hear well in one ear (unilateral) or both ears (bilateral). It is not only a lack of sensory input; it is a complex problem that affects communication, cognitive development, emotional health, and social integration. Depending on the cause, location, and severity, hearing loss can be temporary or permanent, mild or severe.
