| Formatted contents note | 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.<br/><br/>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.<br/><br/>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.<br/><br/>Results of the measurements performed in accordance with ISO 9612:2009 can provide useful information when defining priorities for noise control measures. |
