Screed test stand for measurements on a solid reference ceiling according to DIN EN ISO 10140-1 to -5

At the Fraunhofer IBP screed test stand, the impact sound reduction and airborne sound insulation of ceilings, ceiling coverings, and suspended ceilings, on a solid reference ceiling are examined according to DIN EN ISO 10140. The standardized 140-mm-thick reinforced concrete test ceiling separates two adjacent reverberation rooms, providing optimal conditions for acoustic analyses. Flanking transmission is minimized by additional lining, while the standardized tapping machine and alternative impact sound sources, such as fitness weights or rubber balls, are used for impact noise measurements. The test stand is suitable for floating screeds, cavity floors, raised floors, and various floor coverings. In addition to impact sound measurements, structure-borne sound and modal analyses can also be performed.

Our tests provide you with reliable sound data for optimizing impact sound reduction and enhancing the acoustic quality of your products. With our support, you can meet standards, improve living and working environments, and gain a competitive edge. Rely on our expertise to address acoustic challenges precisely and ensure the long-term success of your products.

Walking sound (walking noise) Apart from the impact sound the walking sound in the sending room can also be measured and weighted.

 

More information

The surface of the separating floor is especially grinded, in order to apply (laying or sticking) thin resilient floor coverings.
