FOREWORD ISO (the International Organization for Standardization) is a worldwide federation of national Standards institutes (ISO Member Bodies). The work of developing International Standards is carried out through ISO Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up 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. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 2922 was drawn up by Technical Committee ISO/TC 43, Acoustics, and circulated to the Member Bodies in December 1972. lt has been approved by the Member Bodies of the following countries : Austral ia Germany Austria Hungary Belgium India Canada Israel Czechoslovakia Mexico Egypt, Arab Rep. of Netherlands Finland New Zealand France Portugal Romania South Africa, Rep. of Switzerland Thailand U.S.A.

INTERNATIONAL STANDARD ISO 29224975 (E) Acoustics - Measurement of noise emitted by vessels on inland water-ways and harbours 1 SCOPE AND FIELD OF APPLICATION This International Standard specifies the conditions for obtaining reproducible and comparable measurements of the noise level and the noise spectrum emitted by vessels of all kinds on inland water-ways and harbours. This International Standard tan also be applied to small sea-going vessels, harbour vessels and dredgers. In the annex, specifications for intake or exhaust noise measurement and measurements with stationary vessels are given. NOTES 1 The test procedures specified in this International Standard are engineering methods as defined in ISO 2204, Acoustics - Guide to the measurement of airborne acoustical noise and evaluation of its effects on man. Note, however, that frequency band analysis is only required for type tests. 2 Measurements may be made on sources emitting noise of an impulsive Character with an impulse Sound level meter (see clause 5). 2 REFERENCES I EC Publication 179, Precision Sound level meters. I EC Publication 225, Octave, half-octave and third-octave band filters intended for the analysis of Sound and vibra tions. 3 NATURE OF TESTS 3.1 type tests : Measurements performed to prove that the vessel delivered by the manufacturer corresponds to noise specifications. The conditions prescribed for each test shall be complied with as closely as possible, but if unavoidable variations have to be made, these must be stated in the test report. 3.2 monitoring tests : Measurements performed in Order to check that the noise of the vessel is still within prescribed Iimits and that no noticeable changes have occurred since the acceptance on initial delivery or after modification, as applicable. For monitoring tests, slight deviation from the test cenditions specified for type tests may be tolerated in respect of the test site, the background noise, the distance between the microphone and the vessel, and the operating condi tions. Any Variation shall be described in the test report. 4 MEASURED QUANTITIES 4.1 All readings of the Sound level meter are to be taken with the dynamic characteristic “fast”. 4.2 The values to be measured at all microphone positions in type and monitoring tests are A-weighted Sound pressure levels LA expressed in decibels (dB). NOTE - If the weighting curve used is not otherwise stated, the measured values shall be expressed in dB (A). 4.3 For spectral analysis in type tests or for the determination of some special acoustical characteristics of vehicles, the values to be measured are octave band or 1/3 octave band Sound pressure levels in decibels (dB). 5 MEASUREMENT EQUIPMENT 5.1 The Sound level meter shall comply with I EC Publication 179. 5.2 If additional measuring equipment, including, for example, a tape recorder and/or level recorder is used, its Overall electro-acoustic Performance shall conform to the relevant clauses of I EC Publication 179. 5.3 For the measurement of noise spectra, the filters shall correspond to IEC Publication 225. 5.4 The Overall acoustic Performance of the measurement equipment shall be checked according to the instructions of the manufacturer, preferably with a Standard Sound Source (for example pistonphone), at the beginning and at the end of each series of measurement. 1 SIST EN 22922:1999

The values shall be expressed in dB (Al) if the weighting curve and the “impulse” dynamic characteristics are not otherwise stated. 7 TEST COURSE AND MEASUREMENT OF DISTANCE 7.1 At the test course, the depth of water must be sufficient for normal Operation of the vessel. 6 ACOUSTICAL ENVIRONMENT, METEOROLOGICAL CONDITIONS, BACKGROUND LEVEL 7.2 During the test, the course of the vessel shall be as straight as possible at the distance from the microphone specified in clause 9. 6.1 The test site propagation exists. shall be such that sufficient free Sound This condition may be consid
