How does it work?
Sound is generated by almost all everyday activity. Impact sound is generated by traffic contacting the floor surface. It is therefore also the main area where a floor covering can influence acoustic performance.
Impact sound made on the floor in 1 room is transmitted through the floor into rooms below. In order to measure the impact sound reduction achieved by a floor covering, impact noise is generated with a hammer machine directly onto the concrete floor slab in an emission room and the sound level (S1) is recorded in the reception room below. The floor covering is then laid onto the concrete slab, the same impact noise is made on the floor covering, and the new sound level (S2) is recorded. The impact sound reduction (EN ISO 717-2) is the difference, measured in decibels, between the 2 sound levels recorded.
The impact sound reduction of Forbo's acoustic project vinyl and linoleum floors ranges from 14 to 19dB.
For schools, proper acoustic performance creates a quiet atmosphere (even if children are running in the corridors) to help children learn. In offices, it reduces stress and aggressiveness. And for hospitals and elderly homes, more peaceful environments help people recover – even if the medical staff is active and noisy. The best way to reduce sound is at the source. That’s why acoustic floors are key when it comes to reducing noise in buildings.
