4 Measurement quantities
4.1 Frequency weighting A shall be used for all measurements. The time weighting shall be set to slow
(S) for all measurements.
4.2 Care should be taken to avoid any influence on the result from unwanted sound signals, for example
noise from the wind on the microphone of the measuring equipment, electrical interferences, or noise
from extraneous sound sources not under consideration.
4.3 The quantities that shall be determined at all microphone positions in acceptance and monitoring
tests are the A-weighted sound exposure level, L , received from the operation of the vessel, and the
E,A,T
maximum AS-weighted sound pressure level, L .
pASmax
4.4 If, in addition to the sound exposure level, spectral analysis in acceptance tests or determination
of some special acoustical characteristics of vessels is needed, the quantities that shall be measured are
the unweighted or C-frequency weighted, octave-band or one-third-octave-band S-time weighted sound
pressure levels, in decibels, at the time of maximum sound pressure, or the unweighted or C-frequency
weighted, octave-band or one-third-octave-band sound exposure levels, in decibels (dB).
4.5 When measurements are made at some distance from the source, the levels observed can be
considerably affected by the weather conditions. For example, the attenuation of sound due to air
absorption is affected by the temperature and humidity of the air. In addition, the refraction of sound
waves due to wind and temperature gradients affect the levels received at a particular position. It is
recommended that measurements taken in extreme or atypical conditions be avoided. If possible, a value
obtained under typical climatic conditions, and an indication of the range of values obtained under other
climatic conditions, should be included in the test report.

4.6 For steady-state noise, as that from a stationary ship's engine, the quantity that shall be measured
is the time-averaged A-weighted sound pressure level, L .
pAeq
5 Measuring equipment
5.1 Equipment specifications
The instruments for measuring sound pressure levels, including microphone(s) as well as cable(s),
recording devices and other accessories, if used, shall meet the requirements for a class 1 instrument
according to IEC 61672-1 for free field or random incidence application, as appropriate. Filters shall
meet the requirements for a class 1 instrument according to IEC 61260-1.
A wind speed anemometer with a maximum permissible error of ±10 % shall be used.
An engine speed tachometer with a maximum permissible error of ±50 r/min shall be used.
5.2 Windscreen
A suitable windscreen shall be used to reduce the influence of the wind on the reading. When it can be
expected that the wind-induced signal will be within 10 dB of the average sound level induced by the
vessel under investigation, windscreens shall be used which, together with the sound level meter, meet
the requirements of a class 1 instrument according to IEC 61672-1.
5.3 Operational check/Calibration
At the beginning and at the end of every measurement session, 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 1 instrument according to IEC 60942. Without any further adjustment, the
difference between the readings of two consecutive checks shall be less than or equal to 0,5 dB. If this
value is exceeded, the results of measurements obtained after the previous satisfactory check shall be
discarded.
In connection with each measurement session and at least at the beginning and the end of each
measurement day, where possible, the impact of residual sound levels on measured results shall be
checked to determine their potential impact on the measurement results.
5.4 Verification
Conformance of the sound pressure level measuring instrument, including the microphone, the
filters and the sound calibrator, with the relevant requirements of IEC 61672-1, IEC 61260-1 and
IEC 60942, respectively, shall be verified by the existence of a valid certificate of conformance from the
manufacturer. Conformance testing in accordance with IEC 61672-3, IEC 61260-3 and ISO 60942:2017,
Annex B, respectively, is required for verification. If applicable, random incidence response of the
microphone shall be verified by a procedure from IEC 61183.
All conformance testing shall be conducted by a laboratory operating in accordance with ISO/IEC 17025
and meeting the maximum-permitted uncertainty defined in IEC 61672-1, IEC 61260-1 and IEC 60942
respectively.
It is recommended that the sound calibrator be calibrated at intervals not exceeding 1 year, that the
conformance of the instrumentation system with the requirements of IEC 61672-1 be verified at
intervals not exceeding 2 years, and that the conformance of analog filters with the requirements of
IEC 61260-1 be verified at intervals not exceeding 2 years. National regulations can require otherwise.
NOTE Testing in accordance with IEC 61672-3 does not fully verify conformance with the requirements of
IEC 61672-1, unless it has been pattern approved in accordance with IEC 61672-2.

6 Test site specifications and environmental conditions
6.1 Test conditions
Two classes of test conditions are considered, namely:
— moving vessels - when the vessel is under way, the requirements of 6.2.1, 6.3 and 6.4 shall apply;
— stationary vessels - when the vessel is alongside a wharf or at anchor, the requirements of 6.2.2, 6.3,
6.4 and 6.5 shall apply.
6.2 Test site specifications
6.2.1 Moving vessels
Within 30 m around the vessel under test and the microphone, there shall be no large surfaces (e.g.
retaining walls, building façades, rocks, bridges) from which sound can be reflected back to the
microphone.
In the vicinity of the microphone, there shall be no obstacles which can disturb the sound field.
Therefore, no person shall be between the microphone and the sound source, and any observers shall
be in such a position that any influence on the meter reading is avoided.
The area between the vessel under test and the measurement microphone shall be open water, free
from any sound absorbing or sound reflecting objects.
6.2.2 Stationary vessels
The surroundings of the microphone up to 30 m shall be free of large, sound-reflecting objects like
barriers, hills, rocks, bridges or buildings.
6.3 Environmental conditions
6.3.1 At wind velocities above 7 m/s, the sound propagation can be disturbed and measurements shall
not be performed unless the user has a method for adjusting the measurements for high wind.
6.3.2 Tests shall be avoided in conditions of rain or other precipitation, and/or when the wave heights
are greater than 0,1 m (World Meteorological Organization (WMO) Sea State 1).

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www .iso .org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.
This third edition cancels and replaces the second edition (ISO 2922:2000), which has been technically
revised.
The important change to the previous edition was to affirm its application to vessels of all sizes. This
third edition also includes a series of small changes such as: the specification of sound pressure level
measurement response (slow), integration time for background noise (5 minutes), and the surf/weather
limitation (Sea State 1) during the survey period. An equation to compute the sound pressure level at
25 m was also added.

3.6
background noise for vessels
background noise
noise from all sources other than the craft under test
EXAMPLE Noise from waves splashing on the measuring craft or the shore, other craft or equipment, and
wind effects.
4 Measurement quantities
4.1 Frequency weighting A shall be used for all measurements. The time weighting shall be set to Slow
(S) for all measurements.
4.2 Care should be taken to avoid any influence on the result from unwanted sound signals, for example
noise from wind on the microphone of the measuring equipment, electrical interference, or extraneous
sound sources not under consideration.
4.3 The quantities to be determined at all microphone positions in acceptance and monitoring tests
are the A-weighted sound exposure level, L , received from the operation of vessel and the maximum
E,A,T
AS-weighted sound pressure level, L , both expressed in decibels.
pASmax
4.4 If, in addition to the sound exposure level, spectral analysis in acceptance tests or determination
of some special acoustical characteristics of vessels is needed, the quantities to be measured are the
unweighted or C-frequency weighted, octave-band or one-third-octave-band S-time weighted sound
pressure levels in decibels at the time of maximum sound pressure, or the unweighted or C-frequency
weighted, octave-band or one-third-octave-band sound exposure levels in decibels.
4.5 When measurements are made at some distance from the source, the levels observed may
be considerably affected by the weather conditions. For example, the attenuation of sound due to air
absorption is affected by the temperature and humidity of the air. In addition the refraction of sound
waves due to wind and temperature gradients will affect the levels received at a particular position. It is
recommended that measurements taken in extreme or atypical conditions be avoided. If possible, a value
obtained under typical climatic conditions, and an indication of the range of values obtained under other
climatic conditions, should be included in the test report.
4.6 For steady-state noise, as that from a stationary ship's engine, the quantity to be measured is the
time-averaged A-weighted sound pressure level, L .
pAeq
5 Measuring equipment
5.1 Equipment specifications
The instruments for measuring sound pressure levels, including microphone(s) as well as cable(s),
recording devices and other accessories, if used, shall meet the requirements for a class 1 instrument
according to IEC 61672-1 for free field or random incidence application, as appropriate. Filters shall
meet the requirements for a class 1 instrument according to IEC 61260-1.
A wind speed anemometer with a maximum permissible error of ±10 % shall be used.
An engine speed tachometer with a maximum permissible error of ±50 r/min shall be used.
5.2 Windscreen
A suitable windscreen shall be used to reduce the influence of wind on the reading. When it can be
expected that the wind-induced signal will be within 10 dB of the average sound level induced by the
