Turn down the volume
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.
Impact sound reduction, how does it work?
Sound is generated by almost all everyday activity. Impact sound is generated by traffic contacting the floor surface. The floor is therefore also the main area where acoustic performance can be influenced.
Impact sound made on the floor in 1 room is transmitted through the floor into rooms below. To measure the impact sound reduction achieved by a floor covering, impact noise is generated with a hammer machine directly onto a 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, and 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 varies from 14 to 19 dB.
