BS EN ISO 9612:2025 - TC
This standard BS EN ISO 9612:2025 - TC Tracked Changes. Acoustics. Determination of occupational noise exposure. Methodology is classified in these ICS categories:
17.140.20 Noise emitted by machines and equipment
13.140 Noise with respect to human beings
17.140.50 Electroacoustics
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.
