What is EN ISO 3993:2017?

EN ISO 3993:2017 is a technical standard that provides guidelines and specifications for the measurement of sound insulation in buildings. It is an important tool used by building professionals to assess and improve the acoustic performance of structures. In this article, we will delve into the key aspects of this standard, its scope, and its significance.

The Scope of EN ISO 3993:2017

EN ISO 3993:2017 primarily focuses on airborne sound insulation, which refers to the reduction of sound transmission between rooms through air-borne sound waves. The standard outlines the procedures and requirements for measuring the sound reduction index and single number rating as indicators of sound insulation performance. It applies to various building elements, including walls, floors, roofs, doors, and windows.

The Significance of EN ISO 3993:2017

This standard serves several essential purposes in the construction industry. Firstly, it ensures that buildings provide adequate sound insulation, promoting privacy and comfort for occupants. Secondly, it helps architects, engineers, and contractors comply with relevant building regulations and codes related to noise control. Moreover, it aids in designing and constructing acoustically efficient buildings in environments with specific noise requirements, such as hospitals, schools, or concert halls.

Understanding the Measurement Process

To measure sound insulation according to EN ISO 3993:2017, a series of laboratory tests are conducted using specialized equipment. These tests involve the transmission of sound from a sound source in one room to a receiving room through the element being tested. The resulting data is then analyzed to determine the sound reduction index and single number rating. The higher the values, the better the sound insulation performance of the element.
