Validity of audiometric screening tests-fact or fiction

J. Gauthier

Abstract


An analysis of the validity of audiometric screening tests has been performed by a repeated measures analysis of variance (MANOVA) on hearing thresholds measured in a screening context, and the corresponding thresholds obtained by clinical tests among the same industrial workers. The results support the feasibility of valid audiometric tests in the context of screening for noise-induced hearing loss. However, they also demonstrate the importance of strict control of all potential sources of variation to obtain valid thresholds. The method used in this study is easy to set up and particularly sensitive to systematic sources of variation; therefore it could be integrated into the procedures applied by audiologists supervising auditory screening
