DIN EN ISO 9612:2007-06

The draft standard specifies an engineering method for determining the exposure of noise in a working environment. The draft standard describes chronological steps for starting with work analysis. Use of different strategies for noise measurement is allowed depending on the purpose of the tests. The method will be useful where an assessment of noise exposure to engineering grade precision is required, for example, for detailed noise exposure studies or epidemiological studies in to the cause of hearing damage. The measuring process requires observation and analysis of the noise exposure conditions so that the quality of the measurements can be controlled. This draft standard provides methods for estimating the uncertainty of the results. This draft 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 protected ear when hearing protectors are worn. Results of the measurements performed in accordance with this International Standard may provide useful information when defining priorities for noise control measures.
