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 10140-4 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This first edition of ISO 10140-4, together with ISO 10140-1, ISO 10140-2, ISO 10140-3 and ISO 10140-5,
cancels and replaces ISO 140-1:1997, ISO 140-3:1995, ISO 140-6:1998, ISO 140-8:1997, ISO 140-10:1991,
ISO 140-11:2005 and ISO 140-16:2006, which have been technically revised.
It also incorporates the Amendments ISO 140-1:1997/Amd.1:2004 and ISO 140-3:1995/Amd.1:2004.
ISO 10140 consists of the following parts, under the general title Acoustics — Laboratory measurement of

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 this part of
ISO 10140 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 ISO 10140-3. This part of ISO 10140
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. It is also intended to incorporate
ISO 140-18 into ISO 10140 (all parts).

4.2 Measurement of sound pressure levels
4.2.1 General
Obtain the energy average sound pressure level using a single microphone moved from position to position,
an array of fixed microphones or a continuously moving microphone.
4.2.2 Minimum separation distances for microphone positions
The following separation distances are minimum values and shall be exceeded where possible:
a) 0,7 m between fixed microphone positions;
b) 0,7 m between any microphone position and the room boundaries;
c) 0,7 m between any microphone position and any diffusers;
d) 1,0 m between any microphone position and the test element;
e) 1,0 m between any microphone position and the sound source.
4.2.3 Averaging times
4.2.3.1 Fixed microphone positions
At each individual microphone position, the averaging time shall be at least 6 s for each frequency band, with
centre frequencies in the frequency range of 100 Hz to 400 Hz. For bands of higher frequencies, it is
permissible to decrease the time to not less than 4 s.
4.2.3.2 Continuously moving microphone
The averaging time shall cover a whole number of traverses and shall not be less than 30 s. Using a moving
