美国国家职业安全健康研究所(NIOSH)在2014年8月发布的健康危害评估(HHE)报告发现,枪支教官在战术训练演习时暴露于高强度的脉冲噪声,显著高于NIOSH上限值140 dB。一联邦机构已要求NIOSH对教官在训练枪械和武器系统时所暴露于的脉冲噪声进行测量,并计算教官每天可以暴露于多少武器射击之内才不会造成显著的听力损失风险。
The National Institute for Occupational Safety and Health (NIH) report of the Health Hazard Assessment (HHE) issued in August 2014 found that firearms instructors were exposed to high intensity impulsive noise during tactical training exercises, well above the NIOSH ceiling of 140 dB . A federal agency has asked NIOSH to measure impulse noise exposed by instructors when training firearms and weapon systems and to calculate how many fire-inscortions an instructor can expose to each day without causing a significant risk of hearing loss.
