Title A regression-based methodology for efficient prediction of broadband attenuation of hearing protectors
Bibliographic information May-June 1992, Vol.38, No.3, p.97-108. Illus. 18 ref.
Abstract Attenuation data were collected on 4 groups of 10 industrial workers each; each group was assigned to one of 4 hearing protection devices which the members used at work for six weeks. Regression models and probabilistic prediction intervals based on these data enabled conservative estimation of a noise reduction rating per subject by measurement of real-ear attenuation in only a single band (500 or 1000Hz). The approach has potential for implementation in the workplace, forecasting a worker's overall protection levels and determination of compliance with exposure limits.
