Title Assessment of noise exposure for indoor and outdoor firing ranges
Bibliographic information Sep. 2007, Vol.4, No.9, p.688-697. Illus. 32 ref.
Abstract NIOSH received a request for a health hazard evaluation from the employees and management of a police department concerned about potential hearing damage from noise generated during weapons training on their indoor and outdoor firing ranges. NIOSH investigators conducted noise sampling with an mannequin head and microphone to characterize the noise exposures that officers might experience during small arms qualification and training when wearing a variety of hearing protection devices provided by the department. The peak sound pressure levels for the various weapons ranged from 156 to 170dB, which are higher than the recommended 140dB exposure guideline from NIOSH. Earplugs, ear muffs and customized hearing protectors provided between 25 and 35dB reduction. Double hearing protection (plugs plus muffs) added a further 15-20dB reduction. Implications of these findings are discussed.
