Sound absorption against impact noises This symbol indicates the sound absorption coefficient at shocks (αw) which is defined by the ratio between the absorbed noise and the incoming noise. This varies by sound frequency. The absorption coefficient is between 0 and 1: 0: the material does not absorb any noise, so the noise is totally reflected 1: all noise is absorbed by the material Acoustic insulation against impact noise This symbol indicates the performance of a floor covering against shock noise. It is measured in dB Slip resistance DS (Dry Slip resistance) This symbol indicates that the floor covering is slip resistant (coefficient of friction higher than 0.3). Slip resistance behaviour NPD (No Performance Determined) This symbol indicates that it has not been tested. Thermal resistance This symbol indicates whether the floor covering is suitable for use on a underfloor heating system.
