This standard specifies the types of sound pressure level measurement methods, sound pressure level measurement locations, sampling methods based on noise limits, frequency analysis, and noise source characteristics. Relevant departments can determine the noise value in the working environment and evaluate the noise in the working environment through on-site measurement, analysis and calculation. This standard does not apply to noise limits for specified working environments.
