The Efficacy of Evoked Otoacoustic Emissions in Identifying Hearing Loss in Children with Developmental Disabilities.
White, Karl R.; And Others
This report describes a project in Utah to investigate the feasibility of using transient evoked otoacoustic emissions (TEOAE) as a tool for screening for hearing loss in children with developmental disabilities (DD). Study participants included 336 students (ages 5 to 7) with no identified DD and 765 students (ages 3 to 7) with one or more DD. Each participant was screened using two conventional pure tone hearing screening protocols and two TEOAE hearing screening protocols. The study found that, overall, the operant characteristics of one of the conventional hearing screening protocols (which used tympanometry screening for the 500 Hz pure tone) were superior to the other measures. However, for nearly one-third of the children with DD, screening results could not be obtained from either of the pure tone screening protocols, whereas successful results were obtained for over 98 percent of the same children using the TEOAE screenings. Results also supported previous findings of a substantially higher incidence of hearing loss in children with DD. The report addresses the project's importance, purpose, accomplishments, methodology, and results. Extensive appendices include necessary approvals for use of human subjects; data collection schedules and summary sheets; a consultant's report; a listing of data dissemination activities, and a summary of participant data.
