The booklet describes Wisconsin's hearing conservation program designed to identify children with impaired hearing, provide diagnostic otologic examinations and evaluations for students with significant losses, provide medical care and educational intervention, and encourage local communities to continue hearing conservation programs. Statistics on the program (related to staff time and identification and followup services) are followed by examples of diagnosis from otologic clinic examinations. The remainder of the guide offers specific suggestions about hearing tests, including information on audiometer nomenclature and performance checks, screening criteria, precautions, post-screening procedures, use of tympanometry, and referral suggestions. Resources in the state for additional help are listed. (CL)
