The EN ISO 10140-2:2018 is a standard that defines the measurement of sound insulation in buildings. It provides guidance on how to conduct laboratory tests to assess the acoustic performance of building elements, such as walls, floors, and doors. The standard is essential for architects, engineers, and construction professionals to ensure that the buildings they design and construct meet the required sound isolation standards.
Scope and Objectives
The main objective of EN ISO 10140-2:2018 is to provide a standardized method for measuring the airborne sound insulation of building elements. The standard outlines the measurement procedures, equipment requirements, and calculation methods to determine the sound reduction index (R) and other relevant acoustic parameters. This enables accurate comparison and evaluation of different building elements in terms of their sound insulation performance.
Measurement Procedures
EN ISO 10140-2:2018 specifies two methods for measuring sound insulation: the single-number quantities and the laboratory measurements with a direct field diffuser. The single-number quantities method determines the apparent airborne sound insulation performance by measuring the difference between the sound pressure levels in the source room and receiving room. The laboratory measurements with a direct field diffuser method evaluates the contribution of the tested element to the overall sound insulation of a partition within a larger test specimen.
Benefits and Applications
Complying with the EN ISO 10140-2:2018 standard has several benefits for both the construction industry and building occupants. By ensuring proper sound insulation, it helps create a comfortable and peaceful indoor environment, especially in areas with high noise levels or sensitive activities such as hospitals, schools, and offices. Compliance with this standard also facilitates international harmonization of sound insulation regulations, making it easier to compare and evaluate building elements across different countries.
In conclusion, EN ISO 10140-2:2018 is a vital standard that provides guidelines for measuring sound insulation in buildings. Compliance with this standard ensures that buildings meet the required sound isolation standards, creating a conducive indoor environment. By promoting international harmonization, this standard facilitates effective comparison and evaluation of building elements in terms of their sound insulation performance.
