| Resumen |
Attenuation data were collected from 40 industrial workers wearing four different hearing protection devices (HPDs) while at work. Statistical analyses indicated that the earplugs' attenuation significantly improved when training for proper fitting was used, whereas the earmuff and canal cap were relatively insensitive to the training effect. Results confirmed that laboratory protocols designed to simulate workplace influences on attenuation may not yield reasonable estimates of field protection performance of HPDs, particularly for earplugs. The study also demonstrated that the labelled manufacturers' noise reduction ratings substantially overestimated the actual field attenuation performance. |
