Acoustics. In-situ measurement of sound insulation in buildings and of building elements. Part 2: Impact noise insulation

This document specifies the methods for measuring airborne and impact sound insulation of buildings and building components on site. It is designed to provide a standardized framework for evaluating acoustic performance in various construction scenarios. The methodology covers the determination of airborne sound insulation as well as the assessment of impact sound transmission through floors and other structural elements. Detailed procedures are outlined for the use of specific equipment, including sound sources and measurement microphones, to ensure consistency and accuracy across different testing environments. Data analysis techniques are included to derive key parameters that characterize the acoustic behavior of the structures under test. This approach facilitates the comparison of results obtained from different sites and supports compliance with relevant building regulations. The content focuses on practical application, guiding technicians and engineers through the step-by-step process of conducting measurements in real-world conditions. By adhering to these protocols, stakeholders can obtain reliable data regarding the sound isolation capabilities of building assemblies.
