标准范围

ISO 9612:2009规定了一种工程方法，用于测量工人在工作环境中的噪声暴露，并计算噪声暴露水平。ISO 9612:2009涉及A加权水平，但也适用于C加权水平。规定了三种不同的测量策略。在需要确定工程级噪声暴露的情况下，该方法很有用，例如用于详细的噪声暴露研究或听力损伤或其他不良影响的流行病学研究。测量过程需要观察和分析噪声暴露条件，以便控制测量质量。ISO 9612:2009提供了评估结果不确定性的方法。ISO 9612:2009不适用于评估口头交流的掩蔽或评估次声、超声波和噪声的非听觉影响。本标准不适用于佩戴听力保护器时耳朵噪声暴露的测量。根据ISO 9612进行的测量结果:2009年可以在确定噪音控制措施的优先次序时提供有用的信息。

ISO 9612:2009 specifies an engineering method for measuring workers' exposure to noise in a working environment and calculating the noise exposure level. ISO 9612:2009 deals with A-weighted levels but is applicable also to C-weighted levels. Three different strategies for measurement are specified. The method is useful where a determination of noise exposure to engineering grade is required, e.g. 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. ISO 9612:2009 provides methods for estimating the uncertainty of the results.ISO 9612:2009 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 ISO 9612:2009 can provide useful information when defining priorities for noise control measures.
