Acoustics - Determination of occupational noise exposure - Engineering method

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.

Acoustics - Method for measuring noise exposure levels in work environments

Le présent document définit une méthode de mesurage de l'exposition au bruit en milieu de travail en vue d'évaluer les niveaux d'exposition quotidienne au bruit et d'identifier les dépassements éventuels des seuils de niveaux de pression acoustique de crète.
