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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 2922 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee
SC 1, Noise.
This second edition cancels and replaces the first edition (ISO 2922:1975), which has been technically revised.

INTERNATIONAL STANDARD ISO 2922:2000(E)
Acoustics — Measurement of airborne sound emitted by vessels
on inland waterways and harbours
1 Scope
This International Standard 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 ISO 14509. This International Standard is applicable to small 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.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

manufacturer, complies with noise specifications or prescribed limits
3.2

noise impact on people exposed to the sound.

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.
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 maxi
