Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 140-16 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 126, Acoustic properties of building products and of buildings, in collaboration with Technical
Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
ISO 140 consists of the following parts, under the general title Acoustics — Measurement of sound insulation
in buildings and of building elements:
⎯ Part 1: Requirements for laboratory test facilities with suppressed flanking transmission
⎯ Part 2: Determination, verification and application of precision data
⎯ Part 3: Laboratory measurements of airborne sound insulation of building elements
⎯ Part 4: Field measurements of airborne sound insulation between rooms
⎯ Part 5: Field measurements of airborne sound insulation of façade elements and façades
⎯ Part 6: Laboratory measurements of impact sound insulation of floors
⎯ Part 7: Field measurements of impact sound insulation of floors
⎯ Part 8: Laboratory measurements of the reduction of transmitted impact noise by floor coverings on a
heavyweight standard floor
⎯ Part 9: Laboratory measurements of room-to-room airborne sound insulation of a suspended ceiling with
a plenum above it
⎯ Part 10: Laboratory measurement of airborne sound insulation of small building elements
⎯ Part 11: Laboratory measurements of the reduction of transmitted impact sound by floor coverings on
lightweight reference floors

ISO 140-16:2006(E)
Introduction
There is a strong need to separately characterize the sound reduction effect of walls or floors and acoustic
linings. On the one hand, different industries are involved. On the other hand, the European calculation model
for the acoustic performance of buildings from the performance of elements distinguishes the sound reduction
index of a wall (or floor) and the improvement of the sound reduction index by an additional lining. The
laboratory measurement of this sound reduction improvement is the subject of this part of ISO 140-16.
Characterizing a lining alone requires that its acoustic performance be independent from the basic structure to
which it is fixed. This is fulfilled when the mass per unit area of the basic structure is much larger than the
surface mass of the lining, when the coincidence frequency of the basic structure is below the measured
frequency range and the structural coupling between the lining and the basic structure is small. If the actual
situation differs from these conditions, the effect of the lining is, at least to some extent, dependent on the
properties of the basic structure. The independent characterization of the acoustic performance of a lining thus
requires very heavy massive elements, while a lot of practical applications involve various lightweight
elements. As a practical compromise, different steps of testing are provided.
2
⎯ In any case, the lining is applied to either a heavy massive wall of about 350 kg/m with its coincidence
frequency around 125 Hz or to the standard concrete floor according to ISO 140-8, depending on the use
of the lining. The measured improvement by the lining is given as a frequency spectrum and as a single-
number improvement value in accordance with Annexes A and B. Being based on mean basic element
characteristics, the results are largely independent of the particular features of the test facility and the
basic element used and thus characterize the lining in the most general way.
⎯ If the performance of a lining on a generalized lightweight solid wall is of interest, a standard lightweight
2
basic wall of about 70 kg/m and coincidence frequency around 500 Hz are used. The results are given
as a frequency spectrum and as a single-number improvement value according to Annexes A and B. The
central position of the coincidence frequency can strongly influence the improvement by the lining.
Therefore, the results are not likely to be transferable to other basic constructions. But by using the
weighting procedure in Annexes A and B, the influences of the particular test facility and basic
construction are minimized, thus making the results comparable between different laboratories.
⎯ In order to specify the effect of linings in specific situations, other basic structures can be used in addition
to those specified for the general characterization of the product. As no mean values of the properties of
the basic element are available in this case, single-number results can only be given in terms of the direct
difference between the weighted sound-reduction indices with and without lining (subsequently called
“direct difference of the weighted sound reduction indices”). These improvement values include the
particular features of the laboratory and the basic element, thus allowing a comparison of different linings
under these particular conditions.
Flexible, lightweight basic elements and elements with thickness resonances within the measured frequency
range are outside the scope of this part of ISO 140, as their influence is not predictable.
For standardization reasons and comparability, all measurements and evaluations are normatively done in
third-octave bands. Additional octave-band results can optionally be deduced from the third-octave band
results.
The sound-reduction improvement of a lining can be different for direct and flanking sound transmission, as
well as for airborne and impact sound excitation. The method described in this part of ISO 140 yields the
sound-reduction improvement for direct airborne sound transmission.
