BS EN ISO 10140-2: 2021
What is ISO 10140-2 about?
ISO 10140-2 is the second part of multiple series that specifies a laboratory method for measuring the airborne sound insulation of building products, such as walls, floors, doors, windows, shutters, façade elements, façades, glazing, small technical elements, for instance, transfer air devices, airing panels (ventilation panels), outdoor air intakes, electrical raceways, transit sealing systems and combinations, for example, walls or floors with linings, suspended ceilings or floating floors.
The test results can be used to compare the sound insulation properties of building elements, classify elements according to their sound insulation capabilities, help design building products that require certain acoustic properties and estimate the in-situ performance of incomplete buildings.
Who is ISO 10140-2 for?
ISO 10140-2 on acoustics laboratory measurement of sound insulation of building elements is useful for:
- Testing acoustic laboratory
- Construction industry
- Civil engineer
- Building contractor
- Manufacturer of industrial production
- Investigator of acoustic
- Land surveyor of acoustic
Why should you use ISO 10140-2?
Airborne sound insulation describes the insulation between rooms separated by a wall or floor partition. It is calculated by combining multiple sound pressure levels and reverb time measurements. The measured frequency range is typically from 50 Hz to 5 kHz.
One of the ways in which airborne sound can be reduced is through the technique of acoustic absorption. ISO 10140-2 enables you to measure the airborne sound insulation of building products for comparing the performance of the different materials/elements in insulating airborne sound. The results obtained can be used to predict the sound insulation of such elements in real building conditions.
ISO 10140-2 aids you to measure laboratory airborne sound insulation by considering two contiguous reverberation rooms, the source room and the receiving room, split by the element to be tested. The rooms need to be mechanically and acoustically insulated in order to verify that the flanking transmissions are minor, which means that almost all the sound is transmitted by the element to be tested, and it is necessary to confirm diffuse fields in the source and receiving room.
What’s changed since the last update?
BS EN ISO 10140-2:2021 supersedes BS EN ISO 101402:2010, which is withdrawn.
The main changes compared to the previous edition are as follows:
- All references in the text have been updated
- In clause 2, the normative references have been updated
- In clause 3, the terms and definitions have been updated
- In clause 8, the title has been changed to “measurement uncertainty”
