Hearing loss, also known as hard of hearing, anacusis or hearing impairment, 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 language and in adults it can cause work related difficulties.
There are four types of hearing loss: 1  Conductive Hearing Loss. Hearing loss caused by something that stops sounds from getting through the outer or middle ear. 2  Sensorineural Hearing Loss. Hearing loss that occurs when there is a problem in the way the inner ear or hearing nerve works. 3  Mixed Hearing Loss.
