EN 16205:2013+A1:2018 (E) 4 Introduction This document sets up a laboratory measurement method to determine noise radiated from a floor covering on a standard concrete floor when excited by a standard tapping machine. The noise is measured in the room where the floor covering and the excitation are located. There is no restriction concerning the type of floor covering unless that the required small pads of the flooring could not be assembled. Using the standard tapping machine according to EN ISO 10140 means that a more general excitation compared to walking alone is regarded – in the same way as it is accepted for impact sound improvement measurements of floor coverings. The results are expressed in terms of the normalised A-weighted average sound pressure level in the walking room. The results provide information about the noise radiated. A more sophisticated psychoacoustic evaluation did not seem to be appropriate in view of the fact that this measurement stands for a large range of sources with different acoustical behaviour (even if only different types of walking were regarded). A subjective classification of the quality of the floor coverings is not intended. SIST EN 16205:2013+A1:2018

Loudness is a linear measure; hence a redoubling of the sone value results in a redoubling of the perceived loudness. Loudness is based on the concept of critical bands. 3.7 critical band loudness-model for human hearing system processes perceived sound in sub-bands called critical bands. Note 1 to entry:
Critical bandwidth differs within the frequency range. Note 2 to entry:
The critical band produces the critical band scale. Its unit is Bark." 4 Principle A floor test facility according to EN ISO 10140 for impact and airborne sound measurements is used. It consists of two medium sized and medium damped rooms above each other, separated by a standard homogeneous concrete floor. As a walking noise source, a standard tapping machine according to EN ISO 10140 is applied. Several average sound pressure level measurements in third-octave bands are made in the upper and lower rooms with the bare floor either uncovered or covered with pads or sufficiently large "full-size" specimens of the tested flooring. In the upper room the reverberation times with large specimens and with merely pads present shall be determined. The walking sound pressure level is then calculated according to Formula (1) from the sound power directly radiated from the floor covering into the upper room plus the sound power from the bare floor under the floor covering, which radiates back into the upper room. Finally the A-weighted walking sound pressure level is calculated from the measured average sound pressure levels. In Formula (1) the radiation from the bare floor through the floor covering is corrected for deviations of the actual laboratory
