声学 职业噪声暴露的测定 方法（ISO 9612:2025）

[中文适用范围]： 本文件规定了在工作环境中测量工人噪声暴露水平以及计算噪声暴露等级的方法。本文件主要针对A计权声级，但也适用于C计权声级。文件中规定了三种不同的测量策略。该方法适用于详细的噪声暴露研究或听力损伤及其他不良影响的流行病学研究。测量过程需要对噪声暴露情况进行观察和分析，以确保测量质量。本文件提供了估计测量结果不确定性的方法。本文件不适用于评估语音通信的掩蔽效应，也不适用于评估次声、超声及噪声的非听觉效应的评估。本文件不适用于佩戴听力保护器时对耳部噪声暴露的测量。按照本文件进行的测量结果在确定噪声控制措施优先级时可提供有用的信息。 [外文原描述]： This document specifies a method for measuring workers’ exposure to noise in a working environment and calculating the noise exposure level. This document deals with A-weighted levels but is applicable also to C-weighted levels. Three different strategies for measurement are specified. The method is applicable for detailed noise exposure studies or epidemiological studies of hearing damage or other adverse effects. The measuring process requires observation and analysis of the noise exposure conditions so that the quality of the measurements can be controlled. This document provides methods for estimating the uncertainty of the results. This document is not intended for assessment of masking of oral communication or assessment of infrasound, ultrasound and non-auditory effects of noise. It does not apply to the measurement of the noise exposure of the ear when hearing protectors are worn. Results of the measurements performed in accordance with this document can provide useful information when defining priorities for noise control measures.
