Deafness is a condition wherein the ability to detect certain frequencies of sound is completely or partially impaired. When applied to humans, the term hearing impaired is rejected by the majority of deaf people where the terms deaf and hard-of-hearing are preferred.
- About 17 percent of adults in the United States, 36 million, report some degree of hearing loss.
- At age 65, one out of three people has a hearing loss.
- 60 percent of the people with hearing loss are either in the work force or in educational settings.
- While people in the workplace with the mildest hearing losses show little or no drop in income compared to their normal hearing peers, as the hearing loss increases, so does the reduction in compensation.
- About 2-3 of every 1,000 children are hard of hearing or deaf
- Estimated that 30 school children per 1,000 have a hearing loss.
