Characteristics of hearing-impaired children in the public schools: part I--demographic data.

Survey questionnaires eliciting incidence information about degree and type of hearing loss, educational placement, use of amplification, and other demographic data were completed by audiologists in 13 of the 15 Area Education Agencies in Iowa in an attempt to describe the characteristics of hearing-impaired children in public-school settings. The information revealed patterns of hearing loss related to age and sex, use of hearing aids, and classroom placement that may be useful in planning support services for this population.
