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 16283-1 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This edition cancels and replaces ISO 140-4:1998, ISO 140-5:1998, ISO 140-7:1998, ISO 140-14:2004, which
have been technically revised.
ISO 16283 consists of the following parts, under the general title Acoustics — Field measurement of sound
insulation in buildings and of building elements:

Introduction
ISO 16283 (all parts) describes procedures for field measurements of sound insulation in buildings. Airborne,
impact and façade sound insulation are described in ISO 16283-1, ISO 16283-2 and ISO 16283-3,
respectively.
Field sound insulation measurements that were previously described in ISO 140-4, -5, and -7 were
(a) primarily intended for measurements where the sound field could be considered to be diffuse, and (b) not
explicit as to whether operators could be present in the rooms during the measurement. ISO 16283 differs
from ISO 140-4, -5, and -7 in that (a) it applies to rooms in which the sound field may, or may not approximate
to a diffuse field, (b) it clarifies how operators can measure the sound field using a hand-held microphone or
sound level meter and (c) it includes additional guidance that was previously contained in ISO 140-14.

DRAFT INTERNATIONAL STANDARD ISO/DIS 16283-1

Acoustics — Field measurement of sound insulation in
buildings and of building elements —
Part 1:
Airborne sound insulation
1 Scope
This part of ISO 16283 specifies procedures to determine the airborne sound insulation between two rooms in
a building using sound pressure measurements. It is intended for room volumes in the range from 10 to
3
250 m in the frequency range from 50 to 5 000 Hz. The test results can be used to quantify, assess and
compare the airborne sound insulation in unfurnished or furnished rooms where the sound field may, or may
not approximate to a diffuse field. The measured airborne sound insulation is frequency-dependent and can
be converted into a single number to characterise the acoustic performance using the rating procedures in
ISO 717-1.

4 Instrumentation
4.1 General
The instruments for measuring sound pressure levels, including microphone(s) as well as cable(s),
windscreen(s), recording devices and other accessories, if used, shall meet the requirements for a class 0 or 1
instrument according to IEC 61672-1 for random incidence application.
Filters shall meet the requirements for a class 0 or 1 instrument according to IEC 61260.
The reverberation time measurement equipment shall comply with the requirements defined in ISO 3382-2.
4.2 Calibration
At the beginning and at the end of every measurement session and at least at the beginning and the end of
each measurement day, the entire sound pressure level measuring system shall be checked at one or more
frequencies by means of a sound calibrator meeting the requirements for a class 0 or 1instrument according
to IEC 60942. Without any further adjustment, the difference between the readings of two consecutive checks
shall be less or equal to 0,5 dB. If this value is exceeded, the results of measurements obtained after the
previous satisfactory check shall be discarded.
4.3 Verification
Compliance of the sound pressure level measuring instrument, the filters and the sound calibrator with the
relevant requirements shall be verified by the existence of a valid certificate of compliance. If applicable,
random incidence response of the microphone shall be verified by a procedure from IEC 61183. All
compliance testing shall be conducted by a laboratory being accredited or otherwise nationally authorized to
perform the relevant tests and calibrations and ensuring metrological traceability to the appropriate
measurement standards.
NOTE Unless national regulations dictate otherwise, it is recommended that the sound calibrator should be calibrated
at intervals not exceeding 1 year, the compliance of the reference sound source with the requirements of ISO 6926 should
be verified at intervals not exceeding two years, the compliance of the instrumentation system with the requirements of
IEC 61672-1 should be verified at intervals not exceeding two years, and the compliance of the filter set with the
requirements of IEC 61260 should be verified at intervals not exceeding two years.
5 Frequency range
All quantities shall be measured using one-third octave band filters having at least the following centre
frequencies, in hertz:
100, 125, 160, 200, 250, 315, 400, 500, 630, 800, 1 000, 1 250, 1 600, 2 000, 2 500, 3 150
If additional information in the low-frequency range is required, use one-third octave band filters with the
following centre frequencies, in hertz:
50, 63, 80
If additional information in the high-frequency range is required, use one-third octave band filters with the
following centre frequencies, in hertz:
4 000, 5 000
NOTE Measurement of additional information in the low- and high-frequency ranges is optional.

ISO/DIS 16283-1
6 General
Determination of the airborne sound insulation according to this part of ISO 16283 requires that one room is
chosen as the source room which will contain the loudspeaker(s), and another is chosen as the receiving
room. The measurements that are required include the sound pressure levels in both rooms with the source(s)
operating, the background noise in the receiving room when all sources are switched off and the reverberation
times in the receiving room.
Two measurement procedures are described that shall be used for the sound pressure level, the reverberation
time and the background noise; a default procedure and an additional low-frequency procedure.
The default procedure for all frequencies is to obtain the energy-average sound pressure level using a fixed
microphone or a manually-held microphone moved from one position to another, an array of fixed
microphones, a mechanized continuously-moving microphone or a manually-scanned microphone. These
measurements are taken in the central zone of a room at positions away from the room boundaries.
The low-frequency procedure shall be used for the 50, 63, 80 Hz one-third octave bands in the source and/or
3
receiving room when its volume is smaller than 25 m (calculated to the nearest cubic metre). This procedure
is carried out in addition to the default procedure and requires additional measurements of the sound pressure
level in the corners of the source and/or receiving room using either a fixed microphone or a manually-held
microphone.
NOTE 1 The low-frequency procedure is necessary in small rooms due to large spatial variations in the sound pressure
level of the modal sound field. In these situations, corner measurements are used to improve the repeatability,
reproducibility and relevance to room occupants.
NOTE 2 If necessary to avoid hearing damage, hearing protection should be worn by the operator when measuring the
sound pressure level in the source room and, if necessary, when measuring reverberation times in the receiving room.
When measuring sound pressure levels in the receiving room that will not cause hearing damage it is advisable to remove
any hearing protection so that the operator is aware of short external noise events that could invalidate the measurement
as well as helping the operator to minimise self-generated noise.
If using methods of signal processing described in ISO 18233 the measurements shall be carried out using
fixed microphones and shall not use a mechanized continuously-moving microphone, manually-held
microphone or a manually-scanned microphone.
The sound fields in typical rooms will rarely approximate to a diffuse sound field over the entire frequency
range fro
