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.
What is severe hearing loss? On average, the most quiet sounds heard by people with their better ear are between 70 and 95 dB. People who suffer from severe hearing loss will benefit from powerful hearing aids, but often they rely heavily on lip-reading even when they are using hearing aids.
