Apart from the absorption of impact noise, textile floors possess good aerial noise absorption properties. The “lifespan” of sounds, in a room equipped with a carpet, is reduced by half as compared with bare, smoothfloored rooms.
• In order to limit the reverberation of noise in buildings, the French regulations require the use of absorbent materials in certain passageways. This rating is calculated using a chart of the αSabine absorption coefficients in octave bands (measured in the laboratory). The usual required threshold is 0.25 in shared premises and the hotel business. These materials are characterised by their unique αw absorption index, calculated on the basis of the curve of the αSabine absorption coefficients in octave bands (measured in the laboratory).
• Most materials used in interior decoration (ceilings, walls and floors) are able to reduce sound reverberation. The overall acoustic absorption of the item (αw) will depend on their individual performances . Using Balsan carpets and tiles (see table) will considerably increase your acoustic absorption performance. The exceptional sound insulation capacity of carpets is confirmed, in particular, in public spaces, such as open-plan offices, reception halls and libraries. Planning the laying of a carpet at the design stage makes it possible to achieve significant savings in terms of acoustic insulation.
In order to provide solutions for acoustic insulation Balsan is going even
further and offering a new tile with an acoustic sublayer containing a
majority of recycled material and delivering improved acoustic performance.
Balsan also offers this Sonic Confort underlay on special order for
the following products: Airbrush, Batik, Boléro, Sérénité dalle, Impression,
Infini Design (Dimensions, Kilt, Ombra, Silva, Tweed), Landscape (Canyon,
Groove, Rift), Mezzo, Pilote, Eco-Pilote, Shades and Stripes.
