AS 1191-2002 Acoustics - Method for laboratory measurement of airborne sound transmission insulation of building elements
Standards Australia
Reconfirmed by: AS 1191-2002 Rec:2016 Acoustics - Method for laboratory measurement of airborne sound transmission insulation of building elements
Contents:
This Standard specifies the method for the laboratory measurement of the airborne sound reduction index of building elements such as walls, floor/ceiling assemblies, doors, windows and other space-dividing elements. Requirements and guidance for the rooms used for measurement are provided. In view of the size constraints of many existing test facilities in Australia, and the high cost of developing large, new facilities, this edition incorporates recommendations on the assessment of diffusivity of sound fields in transmission rooms and on making measurements in low-frequency bands. These recommendations are particularly intended to assist users of smaller test facilities in making valued measurements and in preparing accurate and unambiguous test reports.
