Acoustics - Field measurement of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation (ISO 16283-1:2014)
EN-ISO 16283-1 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 250 m3 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.
Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen - Teil 1: Luftschalldämmung (ISO 16283-1:2014)
Dieser Teil der ISO 16283 legt Verfahren zur Bestimmung der Luftschalldämmung zwischen zwei Räumen in
einem Gebäude durch Schalldruckmessungen fest. Es ist für Raumvolumen im Bereich von 10 m3 bis 250 m3
und den Frequenzbereich von 50 Hz bis 5 000 Hz vorgesehen. Die Prüfergebnisse können genutzt werden,
um die Luftschalldämmung in unmöblierten und möblierten Räumen quantitativ zu bestimmen, zu beurteilen
und miteinander zu vergleichen, wobei das Schallfeld etwa einem diffusen Schallfeld entsprechen darf, dies
jedoch nicht muss. Die gemessene Luftschalldämmung ist von der Frequenz abhängig und kann in eine
Einzahlangabe umgewandelt werden, um unter Anwendung der Bewertungsverfahren nach ISO 717-1 die
akustische Leistung zu charakterisieren.
Acoustique - Mesurage in situ de l'isolation acoustique des bâtiments et des éléments de construction - Partie 1: Isolation des bruits aériens (ISO 16283-1:2014)
L'ISO 16283-1:2014 spécifie les modes opératoires permettant de déterminer l'isolation des bruits aériens entre deux salles d'un bâtiment à l'aide de mesurages de la pression acoustique. Ces modes opératoires s'appliquent aux salles dont le volume est compris entre 10 m3 et 250 m3 aux fréquences comprises entre 50 Hz et 5 000 Hz. Les résultats des essais peuvent être utilisés pour quantifier, évaluer et comparer l'isolation des bruits aériens dans des salles non meublées ou meublées où le champ acoustique peut ou non être assimilé à un champ diffus. L'isolation mesurée des bruits aériens dépend de la fréquence et peut être convertie en une quantité d'indice unique d'évaluation qui caractérise la performance acoustique à l'aide des méthodes d'évaluation spécifiées dans l'ISO 717‑1.
Akustika - Terenska merjenja zvočne izolirnosti stavbnih elementov in v stavbah - 1. del: Izolirnost pred zvokom v zraku (ISO 16283-1:2014)
Standard 16283-1 določa postopke za ugotavljanje izolirnosti pred zvokom v zraku med dvema prostoroma v stavbi z uporabo meritev zvočnega tlaka. Namenjen je prostorom s prostornino 10–250 m3 v frekvenčnem območju 50–5000 Hz. Rezultate preskusa je mogoče uporabiti za kvantifikacijo, ovrednotenje in primerjavo izolirnosti pred zvokom v zraku v neopremljenih ali opremljenih prostorih, kjer je zvočno polje lahko, ali pa ne, podobno razpršenemu polju. Izmerjena izolirnost pred zvokom v zraku je odvisna od frekvence in jo je mogoče pretvoriti v eno številko za opredelitev akustičnih lastnosti z uporabo ocenjevalnih postopkov v standardu ISO 717-1.

Introduction
ISO 16283 (all parts) describes procedures for field measurements of sound insulation in buildings.
3)
Airborne, impact and façade sound insulation are described in ISO 16283-1, ISO 16283-2 and
4)
ISO 16283-3 , respectively.
Field sound insulation measurements that were described previously 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.
NOTE Survey test methods for field measurements of airborne and impact sound insulation are dealt with in
ISO 10052.

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. These procedures are intended for room
3 3
volumes in the range from 10 m to 250 m in the frequency range from 50 Hz 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 quantity
to characterize the acoustic performance using the rating procedures in ISO 717-1.

human operator at a distance at least an arm’s length from the trunk of the operator’s body
3.10
partition
total surface of the separating partition between the source and receiving rooms
Note 1 to entry: For two rooms which are staggered vertically or horizontally, the total surface of the separating
partition is not visible from both sides of the partition; hence it is necessary to define the partition as the total
surface.
3.11
common partition
part of the partition that is common to both the source and receiving rooms

SIST EN ISO 16283-1:2014
ISO 16283-1:2014(E)
Note 2 to entry: The level difference is referenced to a reverberation time of 0,5 s because in dwellings with
furniture the reverberation time has been found to be reasonably independent of volume and frequency and
to be approximately equal to 0,5 s. With this standardization, D is dependent on the direction of the sound
nT
transmission if the source and receiving rooms have different volumes; D will be higher when the test is carried
nT
out from a smaller source room to a larger receiving room compared to the reverse situation. For this reason,
regulations that require testing to show compliance with a minimum standard of airborne sound insulation
usually require that the smaller room is used as the receiving room so that the lowest D values are measured.

3.14
apparent sound reduction index
R’
ten times the common logarithm of the ratio of the sound power, W , which is incident on a test element

A
where
S is the area of the common partition, in square metres;
A is the equivalent absorption area of the receiving room, in square metres.
Note 1 to entry: R’ is expressed in decibels.
Note 2 to entry: In general, the sound power transmitted into the receiving room consists of the sum of several
components from different elements (walls, floor, ceiling etc.).
Note 3 to entry: R’ can be used to compare field measurements with laboratory measurements of the sound
reduction index, R. In comparison to D it has a weaker link to the subjective impression of airborne sound
nT
insulation.
Note 4 to entry: When R’ is determined in the 50 Hz, 63 Hz and 80 Hz bands using the low-frequency procedure
the link to sound power in Formula (3) is not exact.

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
