properties of building elements and of buildings”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2021, and conflicting national standards shall be
withdrawn at the latest by May 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 16205:2013+A1:2018.

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.
1 Scope
This document specifies a laboratory measurement method to determine noise radiated from a floor
covering on a standard concrete floor when excited by a standard tapping machine.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 10140 (all parts) and the
following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
sufficiently large specimen
specimen whose radiated sound power does not increase any longer with size, or which covers the total
area of the floor
Note 1 to entry: In case of uncertainty, the testing laboratory will decide which size is sufficient.
3.2
pads
pieces of the flooring under test, which are as large as the hitting areas of the tapping machine hammers
Note 1 to entry: Quadratic pads should be the smallest possible including the whole hitting area.
3.3
walking sound pressure level (in third-octave band i)
L
n,walk,i
normalized impact sound pressure level in the upper (walking) room with a standardized contribution
of the concrete bare floor underneath the floor covering under test

3.6
loudness
perceived strength of steady-state sound calculated according to Zwicker
Note 1 to entry: Its unit is sone. 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 10140-1 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”
