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 the required small pads of the flooring could not be assembled. Using
the standard tapping machine according to EN ISO 10140 (all parts) 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 normalized 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.

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 10140-1 through EN ISO 10140-5, 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 10140-1 through EN ISO 10140-5 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 floor from the reference spectrum in Annex B. Furthermore, the tapping machine
self-noise theoretically cancels out and, therefore, is not needed explicitly. However, because of the
uncertainty of the measured quantities, the resulting walking sound pressure level in the second line in
Formula (1) may become very uncertain and even complex, in particular when a loud tapping machine is
used and the flooring does not radiate much itself. Complex values are avoided by setting the inner
bracket to zero as a minimum [first line in Formula (1)]. To detect unreliable results, the uncertainty of
Ln,walk shall be calculated for each third-octave band and
