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 ISO 10140-3
contain the general procedures for airborne and impact sound insulation measurements, respectively,
and refer to ISO 10140-4 and this part of ISO 10140 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
ISO 10140-3. ISO 10140-4 contains basic measurement techniques and processes. This part of ISO 10140
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.

4 Laboratory test facilities for airborne sound insulation measurements
4.1 General
The laboratory test facility shall consist of two adjacent reverberant rooms with a test opening between
them, in which the test element is inserted.
The area of the test opening can vary depending on the type of test element. This part of ISO 10140
defines full-sized test openings, a specific small-sized test opening and alternative reduced-size test
openings.
For measurement of the improvement of sound reduction index by acoustical linings, these rooms shall
be separated by a standard basic element on which the lining under test is installed (see Annex B).
4.2 Test rooms
4.2.1 Volume
3
The volumes of the test rooms shall be at least 50 m . Volumes and corresponding dimensions of the
two test rooms should not be exactly the same. A difference of at least 10 % in room volumes and in the
linear dimensions is recommended.
Choose the ratios of the room dimensions such that the eigen mode frequencies in the low-frequency
bands are spaced as uniformly as possible.
When measuring the sound insulation of walls or floors, theoretical calculation as well as experiments
have indicated that the test element should cover a total partition wall or ceiling of the test room, i.e.
the test opening should extend from wall to wall and from floor to ceiling. In such a case, a volume of
3 3
50 m to 60 m is appropriate in view of the recommended size of the test opening.
4.2.2 Diffusion
Large variations of the sound pressure level in the room indicate the presence of dominating strong
standing waves. In this case, diffusing elements shall be installed in the rooms. The positioning and

oSIST prEN ISO 10140-5:2020
ISO/DIS 10140-5:2020(E)

number of diffusing elements should be arranged in such a way that the sound reduction index is not
influenced when further diffusing elements are installed.
NOTE For some kinds of test element, as for elements with one surface significantly more absorbent than the
other (see ISO 10140-2), the installation of diffusing elements is mandatory.
4.2.3 Reverberation time
The reverberation time in the rooms under normal test conditions (with negligible absorption by the
test element) should not be excessively long or short. When the reverberation time at frequencies at
and above 100 Hz exceeds 2 s or is less than 1 s, check whether the measured sound reduction index
depends on the reverberation time. When such a dependence is found, even with diffusers in the rooms,
the rooms shall be modified to adjust the reverberation time, T, such that:
23/
12≤≤TV()/50 (1)
where
V is the value of the room volume, in cubic metres;
T is the reverberation time, in seconds.
Measurement of the reverberation time is given in ISO 10140-4.
4.2.4 Background noise
The background noise level in the receiving room shall be sufficiently low to permit measurements of the
sound transmitted from the source room, considering the power output in the source room and the sound
insulation of the test elements for which the laboratory is intended (see ISO/DIS 10140-4:2020, 4.3).
4.2.5 Suppression of flanking transmission
In laboratory test facilities designed for measuring the sound reduction index, the sound transmitted
by any indirect path should be negligible compared with the sound transmitted through the test
element. One approach to achieve this in such facilities is to provide sufficient structural isolation
between source and receiving rooms. Another approach is to cover all surfaces of both rooms with
linings that reduce the flanking transmission in such a way that the requirements on room volumes and
reverberation times are still met.
Annex A gives methods for estimating the maximum achievable sound reduction index, R´ , which is
max
determined by indirect paths.
4.3 Test opening
A horizontal and a vertical full-sized test opening, as well as a specific vertical small-sized test opening
are defined. Other reduced-size test openings may be applied under certain restrictions.
4.3.1 Full-sized test opening
2 2
The area of the full-sized test opening shall be approximately 10 m for walls, and between 10 m and
2
20 m for floors, with the length of the shorter edge being not less than 2,3 m for both walls and floors.
4.3.1.1 General frame specification
The measured sound reduction index of a test element can be affected by the connections to the
laboratory structure surrounding the element. The mass ratio of the tested structure to the surrounding
2
structure should be taken into consideration. For tests on lightweight structures (m < 150 kg/m ),
© ISO 2020 – All rights reserved 3

---------------------- Page: 11 ----------------------
oSIST prEN ISO 10140-5:2020
ISO/DIS 10140-5:2020(E)

there are no special requirements to be taken into account. For heavier structures under test, it should
be ensured that the loss factor, η, of the test element is not less than that given by Equation (2):
03,
η =+00, 1 (2)
min
f
where
f is the test frequency value, in hertz.
To check this requirement, use as the test element a brick or block wall having a mass of (400 ± 40) kg/
2
m plastered on one side. Measurement of the loss factor is given in ISO 10140-4.
4.3.1.2 Specific requirements on the frame for lightweight twin-leaf partitions
With lightweight twin-leaf partitions, the sound reduction index is affected by vibration transmission
between the wall leaves via the frame of the test opening (see Figure 1). This is influenced by the
mounting conditions in the laboratory test opening and by the material properties and dimensions of
the frame(s). Vibration transmission between the coupled structures of the partition itself (e.g. common
or coupled studs) is dependent on the specific construction of the partition and is a property of the test
element itself. This vibration transmission is not treated in this part of ISO 10140.
In order to improve the reproducibility of the sound reduction index between laboratories for walls,
guidance is given for the mass per unit area of the frame of the test opening. If there is an acoustic break
in the laboratory test opening, the frame on one side of that break should be considered. The mass per
unit area of the frame shall be much larger than the mass per unit area of the heaviest leaf of the double
partition. The ratio of the mass per unit area of the heaviest leaf of the double partition to that of the
frame of the test opening shall be at least 1 : 6. The minimum thickness of the frame should be 100 mm
3
and the minimum depth should be 200 mm. The frame shall have a density of at least 2 000 kg/m .
2
The cross-sectional surface mass shall be more than 450 kg/m . In addition, the frame(s) shall consist
of a homogeneous, massive construction, such as dense concrete or masonry. Wood or metal frames
connecting the two leaves shall not be used.
The surface mass per unit area is calculated from the density, ρ, and the thickness, t, of the elements, as
shown in Figure 2, using Equations (3) and (4):
′
mt=ρ (3)
LL L
where
m′
is the mass per unit area of the test facility wall, in kilograms per square metre;
L
ρ is the density of the test facility wall, in kilograms per cubic metre;
∟
t is the thickness of the test facility wall, in metres.
∟

ee e
where
