ASTM E1014-12

Standard Guide for Measurement of Outdoor A-Weighted Sound Levels

SIGNIFICANCE AND USE
There are numerous situations for which outdoor sound level data are required. These include, but are not limited to, the following:
Documentation of sound levels before the introduction of a new sound source (for example, assessment of the impact due to a proposed use).
Comparison of sound levels with and without a specific source (for example, assessment of the impact of an existing source).
Comparison of sound levels with criteria or regulatory limits (for example, indication of exceedence of criteria or non-compliance with laws).
This guide provides a means for selecting measurement locations, operating a sound level meter, documenting the conditions under which the measurements were performed, and recording the results.
This guide provides the user with information to (1) make and document the sound level measurements necessary to quantify relatively steady or slowly varying outdoor sound levels over a specific time period and at specific places and (2) make and document the physical observations necessary to qualify the measurements.
The user is cautioned that there are many nonacoustical factors that can strongly influence the measurement of outdoor sound levels and that this guide is not intended to supplant the experience and judgment of experts in the field of acoustics. The guide is not applicable when more sophisticated measurement methods or equipment are specified. This guide, depending as it does on simplified manual data acquisition, is necessarily more appropriate for the simpler types of environmental noise situations. As the number of sources and the range of sound levels increase, the more likely experienced specialists with sophisticated instruments are needed.
This guide can be used by individuals, regulatory agencies, or others as a measurement method to collect acoustical data for many common situations. Criteria for evaluating or analyzing the data obtained are beyond the scope of this guide.
Note that this guide is only a me...
SCOPE
1.1 This guide covers the measurement of A-weighted sound levels outdoors at specified locations or along particular site boundaries, using a general purpose sound-level meter.
1.2 Three distinct types of measurement surveys are described:
1.2.1 Survey around a site boundary,
1.2.2 Survey at a specified location,
1.2.3 Survey to find the maximum sound level at a specified distance from a source.
1.3 The data obtained using this guide are presented in the form of either time-average sound levels (abbreviation TAV and symbol LAT, also known as equivalent sound level or equivalent continuous sound level abbreviated LEQ and with symbol LAeqT ) or A-weighted percentile levels (symbol LX).
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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.
