Accoustics—Measurement of sound insulation in buildings and of building elements—Part 3:Laboratory measurements of airborne sound insulation of building elements—Part 3:Laboratory measurements of airborne sound insulation of building elements
This part specifies a laboratory method of measuring the airborne sound insulation of building elements such as walls, floors, doors, windows, facade elements and facades, except those classified as small building elements (for which a measuring method is specified in GB/T 19889.10).
The results obtained can be used to design building elements with appropriate sound insulation properties, to compare the sound insulation properties of building elements and to classify such elements according to their sound insulation properties.
The flanking transmission of test facilities for laboratory measurement is suppressed. Data of measurements made in accordance with the method in this part therefore shall not be applied directly in the field without accounting for other factors affecting sound insulation, especially flanking transmission and loss factor.
