What is EN ISO 31267-2018?

Introduction

EN ISO 31267-2018 is a technical standard that provides guidelines and requirements for the measurement and assessment of sound insulation in buildings. This standard plays a significant role in ensuring acoustic comfort in various types of structures, including residential, commercial, and industrial buildings.

Scope and Application

EN ISO 31267-2018 covers a wide range of topics related to the measurement, assessment, and classification of sound insulation properties. It provides detailed guidance on the procedures for measuring airborne and impact sound insulation, as well as information on the proper use and calibration of the measurement equipment. The standard also specifies the conditions under which the tests need to be conducted and the relevant parameters that should be considered during the assessment process.

Key Requirements

One of the primary requirements set by EN ISO 31267-2018 is the determination of the sound reduction index (R) for different building elements, such as walls, floors, and ceilings. This parameter measures the effectiveness of a component or construction assembly in reducing sound transmission between rooms or spaces. The higher the value of R, the better the sound insulation performance.

Another important aspect covered by the standard is the evaluation of impact sound insulation. This type of insulation refers to the ability of a floor construction to reduce the transmission of impact noises, such as footfall noise, from one room to another. EN ISO 31267-2018 provides clear instructions on how to perform impact sound measurements and determine the impact sound pressure level (L).

Conclusion

EN ISO 31267-2018 is a vital tool for architects, engineers, and acoustic consultants involved in the design and construction of buildings. By following the guidelines and requirements outlined in this standard, practitioners can ensure that their projects meet the necessary acoustic performance criteria and provide a comfortable environment for occupants. It enables the accurate assessment of sound insulation properties, helping to minimize noise pollution and create aesthetically pleasing and functional spaces.
