The floor coverings in the Forbo acoustic collection have been developed and tested to maximise impact sound reduction while meeting the needs of heavy traffic commercial areas. Forbo acoustic flooring contributes to lowering noise disturbance within a building in a number of ways. The result is a more comfortable environment.
There are two types of noise that can cause noise pollution:
In-room impact sound is ambient noise which is generated by impact in the room itself. To measure in-room impact noise, noise pressure is measured inside the room where the impact sound is generated, according to the standard NF-S 31-074. All Forbo’s acoustic collections are in Class A, which is the highest possible rating.
Impact sound reduction is the sound transmitted through the floor from one room to the floors below and is the most commonly quoted sound reduction measure. 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. 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 two sound levels recorded. The impact sound reduction of Forbo's acoustic ranges from 14 to 19 dB.
Depending on installation location, residual indentation is a vital consideration when selecting an acoustic floor. Compact acoustic products deliver a performance similar to compact products in terms of indentation and easy rolling floor.
Always look at both criteria when choosing an acoustic floor and find the right balance for your application between acoustic performance and indentation resistance.
