This section outlines a laboratory procedure for evaluating the acoustic sound insulation performance of building elements. These elements typically include walls, floors, doors, windows, exterior building components, and facades. However, it excludes small-sized components, as their measurement methods are covered in GB/T 19889.10. The results obtained from this testing can serve multiple purposes: they can guide the design of building components with effective sound insulation, allow for comparisons between different components, and help classify them based on their acoustic performance. Additionally, the test setup is designed to minimize lateral sound transmission, ensuring that the measured values accurately reflect the direct sound insulation properties of the tested elements. This method provides a reliable and standardized approach for assessing the acoustic behavior of major building structures in controlled environments.
