1.1This guide covers the measurement of outdoor sound due to a fixed sound source such as a siren, stationary pump, power plant, or music amphitheater. Procedures characterize the location, sound level, spectral content, and temporal characteristics of that sound source at the time of measurement. Users should be aware that wind and temperature gradients can cause significant variations in sound levels beyond 300 m. With appropriate caution, the use of measurements resulting from this guide include but are not limited to:
1.1.1Assessing compliance with applicable regulations,
1.1.2Monitoring the effectiveness of a noise reduction plan,
1.1.3Verifying the effectiveness of measures for mitigation of noise impact,
1.1.4Validating sound prediction models, and
1.1.5Obtaining source data for use in sound prediction models.
1.2This standard does not purport to address all of the safety concerns, if any, associated with its use.
