What is EN ISO 11681-8:2016?

EN ISO 11681-8:2016 is a technical standard which provides guidelines for the measurement of sound insulation in buildings and building elements. This standard specifies the procedures and equipment to be used when conducting field measurements to assess the airborne sound insulation of walls, floors, ceilings, and doors.

Scope of EN ISO 11681-8:2016

The scope of this standard covers both new and existing buildings. It applies to all types of buildings, including residential, commercial, and industrial buildings. The measurements carried out in accordance with this standard can be used to determine the sound reduction index (R) of building elements, which is an essential parameter in assessing the acoustic performance of buildings.

Measurement Procedure

The measurement procedure described in EN ISO 11681-8:2016 involves placing a loudspeaker in the source room and a microphone in the receiving room. The loudspeaker emits a pink noise signal, and the microphone measures the sound pressure level in the receiving room. By comparing the measured sound pressure level with the incident sound pressure level, the sound reduction index of the building element can be determined.

It is important to note that the measurements should be taken under standardized conditions to ensure accurate and comparable results. The standard provides guidance on factors such as the positioning of the loudspeaker and the microphone, as well as the correction factors that need to be applied to the measured data.

Benefits of EN ISO 11681-8:2016

Accurate measurement of sound insulation is crucial in creating comfortable living and working environments. EN ISO 11681-8:2016 provides a standardized approach to assess the airborne sound insulation performance of buildings and building elements. This ensures that the acoustic properties of buildings are measured consistently, allowing for reliable comparisons between different structures.

The availability of a comprehensive technical standard like EN ISO 11681-8:2016 also helps architects, engineers, and constructors in designing and constructing buildings with better sound insulation capabilities. By following the procedures outlined in the standard, they can ensure that the buildings meet the necessary acoustic requirements and provide a high level of comfort for their occupants.
