Introduction
ISO 10140 (all parts) concerns laboratory measurement of the sound insulation of building elements
(see Table 1).
ISO 10140-1 specifies the application rules for specific elements and products, including specific
requirements for preparation, mounting, operating and test conditions. ISO 10140-2 and this part of
ISO 10140 contain the general procedures for airborne and impact sound insulation measurements,
respectively, and refer to ISO 10140-4 and ISO 10140-5 where appropriate. For elements and products
without a specific application rule described in ISO 10140-1, it is possible to apply ISO 10140-2 and
this part of ISO 10140. ISO 10140-4 contains basic measurement techniques and processes. ISO 10140-5
contains requirements for test facilities and equipment. For the structure of ISO 10140 (all parts), see
Table 1.
ISO 10140 (all parts) was created to improve the layout for laboratory measurements, ensure
consistency and simplify future changes and additions regarding mounting conditions of test elements
in laboratory and field measurements. It is intended for ISO 10140 (all parts) to present a well-written
and arranged format for laboratory measurements.
It is intended to update ISO 10140-1 with application rules for other products.

Acoustics — Laboratory measurement of sound insulation
of building elements —
Part 3:
Measurement of impact sound insulation
1 Scope
This part of ISO 10140 specifies laboratory methods for measuring the impact sound insulation of floor
assemblies.
The test results can be used to compare the sound insulation properties of building elements, classify
elements according to their sound insulation capabilities, help design building products which require
certain acoustic properties and estimate the in situ performance in complete buildings.
The measurements are performed in laboratory test facilities in which sound transmission via flanking
paths is suppressed. The results of measurements made in accordance with this part of ISO 10140
are not applicable directly to the field situation without accounting for other factors affecting sound
insulation, such as flanking transmission, boundary conditions, and loss factor.
A test method is specified that uses the standard tapping machine (see ISO 10140-5:2020, Annex E) to
simulate impact sources like human footsteps when a person is wearing shoes. This part of ISO 10140 is
applicable to all types of floors (whether heavyweight or lightweight) with all types of floor coverings.
The test method applies only to laboratory measurements.
NOTE When the aim of impact sound insulation measurements is to have a strong correlation between a
“real” impact source (e.g. a person walking or children jumping) and an artificial impact source (e.g. a tapping
machine), it is intended that both sources apply the same input force spectrum to ensure the correct ranking of
floors and floor coverings for the “real” and the artificial source, and it is intended that the impedance spectra of
the sources be the same. If the “real” impact source is a walking person without shoes and the artificial source is
a standard tapping machine such as that specified in Clause 4, the correlation is not strong.
An alternative method, using a heavy/soft impact source for assessing the impact sound insulation of
a floor against impact sources with strong low-frequency components, such as human footsteps (bare
feet) or children jumping, is given in Annex A. Alternative impact sources (i.e. a proposed modification
of the standard tapping machine to make its dynamic source characteristics similar to those of a person
walking barefoot and a heavy/soft impact source with dynamic source characteristics similar to those
of children jumping) are defined in ISO 10140-5:2020, Annex F.
A method to test floor coverings is described in ISO 10140-1:2020, Annex H, for single- or multi-layer
floor coverings installed on specific reference floors. In the case of multi-layer coverings, they can be
factory-assembled or assembled at the test site.

Requirements for equipment used to measure the sound level, and for calibration of that equipment, are
given in ISO 10140-5.
NOTE Alternative methods using a modified tapping machine or a standard heavy/soft impact source can
provide information suitable for assessing the impact sound insulation of a floor or a floor covering against
common impact sources, for instance a person walking without shoes or a child jumping. Procedures for
measurements using a heavy/soft impact source are given in Annex A, with requirements for alternate impact
sources given in ISO/DIS 10140-5:2020, Annex F.
5 Test procedure and evaluation
5.1 General procedure
Two vertically adjacent rooms are used, the upper one being designated the “source room” and the lower
one the “receiving room”. A floor, which is the test element, separates these two rooms (see Clause 6).
The impact source is placed on top of the test element at different positions and the sound pressure
levels are measured in the receiving room, normally in the frequency range of 100 Hz to 5 000 Hz
(optional down to 50 Hz). The equivalent sound absorption area in the receiving room is calculated from
reverberation time measurements. From the sound pressure levels in the receiving room, the quantities
described in Clause 3 shall be evaluated by taking into account the equivalent absorption area. The
procedures used to determine the energy average sound pressure level corrected for background noise
and the reverberation time are specified in ISO/DIS 10140-4:2020, 4.2 and 4.3.
Precautions should be taken to verify that airborne sound transmission from the source to the receiving
room (including any leakage at the perimeter of the test element) is at least 10 dB below the level of
transmitted impact sound in each frequency band, see 5.4.
A method for testing floor coverings is described in ISO/DIS 10140-1:2020, Annex H, for single- or multi-
layer floor coverings installed on specific reference floors. In the case of multi-layer coverings, they
may be factory-assembled or assembled at the test site.
5.2 Generation of sound field
The impact sound shall be generated by the standard tapping machine, as specified in Clause 4. Each set
of measurements should be made with as many impact source positions as necessary to yield a reliable
mean value.
NOTE When the aim of impact sound insulation measurements is to have a strong correlation between a
“real” impact source (e.g. a person walking or children jumping) and an artificial impact source (e.g. a tapping
machine), both sources apply the same input force spectrum, to ensure the correct ranking of floors and floor
coverings for the “real” and the artificial source, and the impedance spectra of the sources are the same. If the
“real” impact source is a walking person without shoes and the artificial source is a standard tapping machine
such as that specified in Clause 4, the correlation is not strong.
An alternative method, using a heavy/soft impact source for assessing the impact sound insulation of
a floor against impact sources with strong low-frequency components, such as human footsteps (bare
feet) or children jumping, is given in Annex A. Alternative impact sources (i.e. a proposed modification
of the standard tapping machine to make its dynamic source characteristics similar to those of a person
walking barefoot and a heavy/soft impact source with dynamic source characteristics similar to those
of children jumping) are defined in ISO 10140-5:2020, Annex F.
Also other types of impact sources can be applied, as for example rainfall on roofs and roof elements.
Such sources are defined in ISO 10140-5:2020, Annex H, while the specific application is treated in
ISO 10140-1:2020, Annex K.
When a floor element includes a soft covering, the standard tapping machine shall fulfil special
requirements (specified in ISO/DIS 10140-5:2020, Annex E). If the test surface is covered with an
extremely soft covering or the surface is very uneven, such that the hammers are not able to fall down
© ISO 2020 – All rights reserved 3

oSIST prEN ISO 10140-3:2020
ISO/DIS 10140-3:2020(E)

the requisite 40 mm to the surface on which the supports rest, pads may be used under the supports to
ensure the correct falling height of 40 mm.
The impact sound pressure levels can reveal a time dependency after the tapping has started. In such
a case, the measurements should not begin until the noise level has become steady. The measurement
period shall be reported. If stable conditions are not reached after 5 min, the measurements should be
carried out over a well-defined measurement period.
For testing a floor, the tapping machine shall be placed in at least four different positions. The minimum
distance between tapping machine positions shall be at least 0,7 m. The distance of the tapping machine
from the edges of the floor shall be at least 0,5 m.
For heavyweight homogeneous floors, such as solid concrete, the positions and orientation of the
tapping machine shall be randomly distributed over the whole area of the floor under test.
For inhomogeneous floor constructions (such as hollow core concrete slabs or lightweight floors with
ribs, beams, joists, etc.) or floors with rough and/or irregular floor coverings, additional positions
should be used to yield a reliable mean value. The positions shall be randomly distributed on the floor
under test. The line of hammers shall be orientated at 45° to the direction of the beams, ribs or joists
(see ISO/DIS 10140-1:2020, H.4.6.2).
Additional requirements for positioning the tapping machine when testing floor coverings are given in
ISO/DIS 10140-1:2020, Annex H. Each set of measurements (bare floor and covered floor) shall be made
with as many machine positions as necessary to yield a reliable mean value, but the specific locations
and the number of positions depend both on the category of floor covering and on the type of reference
floor on which the covering is installed.
The sound field in the receiving room shall not be affected by the presence of people in the source or
receiving room during the tests.
5.3 Data processing
Calculate the normalized impact sound pressure levels (as defined in Clause 3) from the measured (and,
if necessary, corrected-for-background noise) energy average sound pressure levels in the receiving
room and the measured reverberation times, as described in ISO/DIS 10140-4:2020, 4.2, 4.3, 4.5 and 4.6.
If normalized impact sound pressure levels are needed in octave bands, these values shall be calculated
from the three one-third octave band values in each octave band using Equation (2):
3
 
L 10
n,1/3oct,j
 
L = 10 lg 10 (2)
∑
n,oct
 
j=1
 
Perform all calculations with the appropriate accuracy and present the final results with a precision no
higher than the nearest 0,1 dB.
The evaluation of the single-number rating from the results in one-third octave bands shall be done in
accordance with ISO 717-2.
5.4 Correction of airborne sound transmission
In case that the airborne sound transmission from the source to the receiving room cannot be neglected
(this applies to situations where airborne and impact sound pressure level in the receiving room differ
by less than 10 dB, for instance for long reverberation times in the source room or floors with good
impact but poor airborne sound insulation) the measured impact sound shall be corrected. Make the
correction in the following way:
a) Place the loudspeaker at the edge of the source room at a distance of 1,0 m from the closest wall,
and height of 1,0 m from the floor (both distances are relative to the centre of the loudspeaker).
Only one (1) loudspeaker position is required. With the loudspeaker source on, the resulting sound
