|Significance and Use|
4.1ï¿½Situations for which outdoor sound level data are required include, but are not limited to, comparison of sound levels with criteria or regulatory limits.
4.2ï¿½This guide provides information to (4.3ï¿½These sound measurements should be performed by or under the direction of a person experienced in the measurement and analysis of outdoor sound, and who is familiar with the use of the required equipment and techniques.
4.4ï¿½This guide can be used by individuals, regulatory agencies, or others as a measurement guide to collect data on the sound level received from a fixed source within the constraints cited in Section and and .
4.5ï¿½This guide can be used to establish compliance or noncompliance at the time, distance, and conditions during which the data were obtained. However, this guide is only a measurement procedure and does not address the problem of projecting the acquired data outside those conditions, other times of day, other distances, or comparison with specific criteria. In particular, for a given sound source level, distant noise levels will often be found to be greater at night than during the day.
1.1ï¿½This 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:
1.1.1ï¿½Assessing compliance with applicable regulations,
1.1.2ï¿½Monitoring the effectiveness of a noise reduction plan,
1.1.3ï¿½Verifying the effectiveness of measures for mitigation of noise impact,
1.1.4ï¿½Validating sound prediction models, and
1.1.5ï¿½Obtaining source data for use in sound prediction models.
1.2ï¿½This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3ï¿½This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
