Title The performance of circumaural hearing protectors by dosimetry
Bibliographic information Sep. 1983, Vol.25, No.9, p.679-682. 4 ref.
Abstract Noise attenuation of various models of earmuffs was measured by dosimeters while 101 subjects were exposed to noise levels of 86-108dBA. Criteria studied were: physical conditions of the subject (long hair, safety glasses, cap/turban); age, fit, and condition of earmuffs; noise exposure level. A mean attenuation of 20.3dB was obtained. Most of the problems involved in the use of hearing protectors can be overcome by education of workers and proper fitting.
