2002年1月，国家职业安全与健康研究所(NIOSH)收到一份雇员请求，要求对一支特种武器突击队(SWAT)进行健康危害评估。该部门担心在室内和室外射击场进行武器训练时会产生噪音，并可能对听力造成损害。NIOSH调查人员使用声学人体模型头部和1/4英寸麦克风进行噪音采样，以表征警官在佩戴该部门提供的各种听力保护装置进行轻武器资格认证和培训期间可能遇到的噪音暴露。各种武器的峰值声压级从156至170分贝(分贝SPL)不等，高于NIOSH建议的允许140分贝SPL暴露准则。耳塞、耳罩和定制的特警队听力保护器提供了25至35分贝的峰值降低。双重听力保护(插头加护套)增加了15-20分贝的峰值降低。
The National Institute for Occupational Safety and Health (NIOSH) received an employee request for a health hazard evaluation of a Special Weapons Assault Team (SWAT) in January 2002. The department was concerned about noise exposures and potential hearing damage from weapons training on their indoor and outdoor firing ranges. NIOSH investigators conducted noise sampling with an acoustic mannequin head and 1/4 -inch 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 170 decibels (dB SPL), which are greater than the recommended allowable 140 dB SPL exposure guideline from NIOSH. The earplugs, ear muffs, and customized SWAT team hearing protectors provided between 25 and 35 dB of peak reduction. Double hearing protection (plugs plus muffs) added 15–20 dB of peak reduction.
