ASA S12.13 TR – Evaluating the Effectiveness of Hearing Conservation Programs through Audiometric Data Base Analysis

This ANSI Technical Report describes methods for evaluating the effectiveness of hearing conservationprograms in preventing occupational noise-induced hearing loss by using techniques for audiometric database analysis.The rationale is given for using the variability of threshold measurements in annual monitoringaudiograms as the basis for judging effectiveness.Guidelines are discussed concerning how to select arestricted data base to which the analysis procedures will be applied.Specific procedures for data analysisare defined, and criterion ranges are given for classifying program effectiveness as acceptable, marginal, orunacceptable.Sample results for industrial audiometric data bases contributed to Working GroupS12/WG12 are included as an annex for reference and illustration.
