Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements

SCOPE
1.1 This test method covers the laboratory measurement of airborne sound transmission loss of building partitions such as walls of all kinds, operable partitions, floor-ceiling assemblies, doors, windows, roofs, panels, and other space-dividing elements.
1.2 Laboratory Accreditation—A procedure for accrediting a laboratory for performing this test method is given in Annex A3.
1.3 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.

Loss of Building Partitions and Elements
This standard is issued under the fixed designation E 90; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This test method is part of a set for evaluating the sound-insulating properties of building elements.
It is designed to measure the transmission of sound through a partition or partition element in a
laboratory. Others in the set cover the measurement of sound isolation in buildings (Test Method
E 336), the laboratory measurement of impact sound transmission through floors (Test Method E 492),
the measurement of impact sound transmission in buildings (Test Method E 1007), the measurement
of sound transmission through building facades and facade elements (Guide E 966), the measurement
of sound transmission through a common plenum between two rooms (Test Method E 1414), a quick
method for the determination of airborne sound isolation in multiunit buildings (Practice E 597), and
the measurement of sound transmission through door panels and systems (Test Method E 1408).
