This study concludes that the 3M™ E-A-Rfit™ Validation System can help to identify individual workers who are at risk for noise-induced hearing loss from workplace exposure. Additionally, the study highlights the benefit of training individual workers on the correct use of hearing protectors and assists with hearing protector selection. The Field attenuation estimation system fit testing methodology and the interventions that accompany the fit-testing process assist with training and result in higher attenuation for those at risk and is maintained over time.
