Annex E
(informative)
Calculation of perceived walking loudness on floor coverings installed
floating
E.1 General
This annex specifies a method for calculating the perceived acoustic properties of floor coverings
installed floating regarding reflected walking sound. Reflected walking sound is the sound radiated in a
room from walking in the same room. The method describes how to calculate the perceived loudness of
the radiated sound whereby the frequency-dependent values of the drum sound from Clause 6 are
converted into a single number of the loudness. It shows a positive correlation to the sound generated
by a walking person with a hard heel.
E.2 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
E.2.1
Reflected Walking Sound (RWS)
subjective perceived loudness radiated from a floor when a person with hard heel is walking on it
E.2.2
joudness
perceived strength of steady-state sound calculated according to Zwicker. Its unit is sone.
NOTE 1 to entry: Loudness is a linear measure; hence a redoubling of the sone value results in a redoubling of
the perceived loudness.
NOTE 2 to entry: Loudness is based on the concept of critical bands.
E2.3
critical band
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
E.3 Data processing
E.4 Data measured
The data used for the calculation consists of:
— individual 1/3 octave band spectra L , with (impact sound pressure level measured in the upper
i
room, when a sufficiently large specimen is lying on the test floor).
SIST EN 16205:2013/oprA1:2017
EN 16205:2013/prA1:2017 (E)
E.5 Calculations
E.5.1 Sound spectrum L
i,loud
The outcome of the data processing is one average 1/3 octave band spectrum (100 Hz to 5 000 Hz). This
resulting spectrum will be used as input for the loudness calculation.
The sound spectrum L' is the energetic average of the measured spectra:

with
k = 1.n (number of measurement);
i = 1/3 octave band number;
L'i,with,k individual sound spectrum of the k-th measurement.
E.5.2 Loudness RWS
The RWS value is calculated according to ISO 532 B (1975), using method B (Zwicker) for stationary
signals and for diffuse field condition. The input is the one-third octave band spectrum L’ . The
i,loud
conversion routine requires the full frequency range from 25 Hz to 12 500 Hz. The missing levels for
frequencies below 100 Hz and above 3 150 Hz are set to −60 dB. The critical bands are listed in
Table E.2.
NOTE 1 There exists a free downloadable Excel sheet which performs all the calculations of Annex E (scaling
plus loudness calculation). The loudness algorithm is published as a Basic program in DIN 45631 [9] or Zwicker
[10] and it is programmed as a Visual Basic Program within this Excel sheet.
