What is Hearing Impairment?
Individuals with hearing impairments make up .11% of the school-age population, and 1.2% of the students served under IDEA (U.S. Department of Education 2005). Hearing impairments range in severity from mild to moderate to severe to profound, with the greatest educational distinctions occurring between hard of hearing and deaf. Individuals classified as hard of hearing can hear speech tones when wearing hearing aids, while persons who are deaf cannot hear even with hearing aids.
The age that a child loses hearing affects the degree of language delay and development. Children who are born with deafness have congenital hearing losses (prelingual) and more
difficulty with language development than those who acquire deafness after age 2 (postlingual).
