本标准规定了成年人群因不同噪声暴露级和暴露时间引起的永久性听阈值改变的计算方法,评价其每天重复性噪声暴露引起听力损伤的危险率。 当常用听力测量频率或这些频率组合的听阈的值超出一定值时,本标准提供各种公式计算听力障碍依据。 作用于人群的危险噪声暴露用平均A[计权]声暴露级(声压平方
Acoustics. Determination of occupational noise exposure and estimation of noise-induced hearing impairment
本标准规定了测量水下噪声的条件和方法,以使所获得的测量数据结果能够对照和比较。本标准适用于大洋深海、陆架浅海、港口和海湾等处所的水下噪声测量。 本标准的适用频率范围:20Hz~20kHz. 本标准规定的测量结果可以为声纳系统设计、水声装备作用距离分析和预估、舰艇水下辐射噪声测量的背景修正等的分析
