ASTM E1780-12

Standard Guide for Measuring Outdoor Sound Received from a Nearby Fixed Source

SIGNIFICANCE AND USE
Situations for which outdoor sound level data are required include, but are not limited to, comparison of sound levels with criteria or regulatory limits.
This guide provides information to (1) measure outdoor sound level in the vicinity of outdoor fixed noise sources, and (2) document other observations necessary for the measurements. This guide provides a standard procedure for a trained acoustical professional that will produce results and documentation which are consistent with the purposes cited in 1.1.1-1.1.5.
These 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.
This 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 8 and Appendix X1 and Appendix X2.
This 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.
SCOPE
1.1 This 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:
1.1.1 Assessing compliance with applicable regulations,
1.1.2 Monitoring the effectiveness of a noise reduction plan,
1.1.3 Verifying the effectiveness of measures for mitigation of noise impact,
1.1.4 Validating sound prediction models, and
1.1.5 Obtaining source data for use in sound prediction models.
1.2 This 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 and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
This is one of a series of standards and guidelines for measurement and evaluation of community
noise. Also in preparation is a standard method for preparing a measurement plan and a guide to
determine the validity and significance of outdoor noise measurement data. Techniques and
precautions in this guide are not fixed or mandatory and cannot replace the judgment of acoustical
professionals. Rather, this guide is a summary of processes found to be productive and useful in
ensuring that meaningful information will be gathered in an efficient manner about fixed sources of
noiseinacommunityastheyeachmayexist.OthersinthisseriesincludeGuideE1014,whichcovers
manual A-Weighted measurements of outdoor noise using a simple meter, and Test Method E1503.
ANSI 12.18 provides a method of obtaining repeatable sound pressure level measurements of the
sound emitted by a source. This document differs in that atmospheric and ground effects are not
controlled. Thus, the results may not repeat if atmospheric conditions or ground conditions between
the source and the measurement position change. This guide provides only a method of accurately
documenting the sound levels occurring at the measurement position at the time of measurement.
1. Scope
1.1 This 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 (1000 ft).m.With appropriate caution, the use of measurements resulting from this guide
include but are not limited to:
1.1.1 Assessing compliance with applicable regulations,
1.1.2 Monitoring the effectiveness of a noise reduction plan,
1.1.3 Verifying the effectiveness of measures for mitigation of noise impact,
1.1.4 Validating sound prediction models, and
1.1.5 Obtaining source data for use in sound prediction models.
1.2This guide may be used according to Guide E1779 and specified in the measurement plan.
1.2.1This guide can also be used to conduct measurements without a plan provided an operator/observer whose qualifications
are satisfactory to both the performing organization and the user of the results is present at all times during the measurements and
who complies with the applicable requirements of this guide, including record keeping.
1.3
1.2 This 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 and health practices and determine the applicability of regulatory
limitations prior to use.
