Hearing loss, also called as hearing impairment, is a partial or complete inability to hear. A deaf person has little to no hearing. Hearing loss may arise in one or both ears. In some people, particularly older people, hearing loss can result in loneliness. Hearing loss can be temporary or permanent. Hearing loss may be caused by a number of factors like genetics, age, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. Hearing loss can be caused by many different reasons, some of which can be successfully treated with medicine or surgery, depending on the disease process. Hearing loss can be characterised by which part of the auditory system is damaged. There are three basic types of hearing loss conductive, sensorineural, and mixed hearing loss.
