Título Improving the protection afforded by earmuffs to employees who are exposed to noise
Información bibliográfica Sep.-Oct. 1989, Vol.33, No.2, p.67-76. Illus. 13 ref.
Resumen This study investigated causes of variations in the protection afforded by earmuffs among different wearers. Microphones were installed in five earmuff cups worn by workers in an electronics factory where the noise was due to a large lamination press. Real-time measurements of sound level pressure were made both before and after instruction on how to fit the earmuffs correctly. Results showed that simple instruction on how to fit the hearing protectors gave an overall improvement in protection of 4dB. The effect of wearing safety spectacles was found to be negligible. Subjects with short hair tended to achieve higher levels of protection than those with long or curly hair.
