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 of 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 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. It also incorporates the amendment ISO 2922:2000/Amd 1:2013.
The main changes compared to the previous edition are as follows:
— clarification in the Scope that the document is applicable to vessels of all speeds and lengths;
— specification of: sound pressure level measurement response (slow), in 4.1; integration time for
background noise (5 min), in 6.4; and the surf/weather limitation (sea state 1), in 6.3.2, during the
survey period;
— addition of a formula to compute the sound pressure level at 25 m in 10.1.4.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

INTERNATIONAL STANDARD ISO 2922:2020(E)
Acoustics — Measurement of airborne sound emitted by
vessels on inland waterways and harbours
1 Scope
This document specifies the conditions for obtaining reproducible and comparable measurement results
of the airborne sound emitted by vessels of all kinds, on inland waterways and in ports and harbours,
except powered recreational craft as specified in the ISO 14509 series. This document is applicable to
sea-going vessels, harbour vessels, dredgers, and all watercraft, including non-displacement craft, used
or capable of being used as a means of transport on water. There are no limitations to the application
of this document with regard to speed, length and height of vessels, as long as the ship is determined to
act like a point source at the reference distance of 25 m.
All noise data obtained in accordance with this document are referred to a reference distance of 25 m.

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 .
