ASTM E1014 - 12

Standard Guide for Measurement of Outdoor A-Weighted Sound Levels

Status : Current   Published : January 2012



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 L AT, also known as equivalent sound level or equivalent continuous sound level abbreviated LEQ and with symbol L AeqT ) or A-weighted percentile levels (symbol L X).

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.
