Full title and description

ISO 2923:1996/Cor 1:1997 — Acoustics — Measurement of noise on board vessels — Technical Corrigendum 1. This one-page corrigendum provides corrections and editorial/technical clarifications to the international standard ISO 2923:1996 and is intended to be used together with the main 1996 edition.

Abstract

ISO 2923:1996 defines techniques and conditions for measuring noise on board vessels so that results can be used to compare different vessels, support acceptance and regulatory testing, perform monitoring and investigations, and assess audibility of acoustical alarms. The 1997 corrigendum issues corrections to the published 1996 text; it does not by itself replace the standard but amends it.

General information

• Status: Published (corrigendum to ISO 2923:1996).
• Publication date: 3 July 1997 (ISO 2923:1996/Cor 1:1997).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 17.140.30 (Noise emitted by means of transport); 47.020.01 (General standards related to shipbuilding and marine structures).
• Edition / version: Edition 2 (1996) with Technical Corrigendum 1 issued 1997.
• Number of pages: 1 (corrigendum document).

Scope

The corrigendum applies to ISO 2923:1996 (Acoustics — Measurement of noise on board vessels) and supplies corrections and clarifications to the published text. It is intended to be read and applied together with the 1996 edition; the underlying scope of ISO 2923 (measurement positions, instrumentation, measurement conditions and reporting for shipboard noise) remains unchanged.

Key topics and requirements

• Corrections and editorial/technical clarifications to ISO 2923:1996 (text, figures or references as applicable in the corrigendum).
• Measurement of noise on board vessels: recommended instrumentation, measurement positions and operational conditions as specified in ISO 2923:1996.
• Procedures for data averaging, frequency weighting and reporting to ensure comparable results between vessels.
• Requirements for documentation and presentation of results to support acceptance testing, regulatory comparison and further investigations.
• Instruction to apply corrigendum amendments together with the base standard text (do not treat the corrigendum as a standalone replacement).

Typical use and users

Used by naval architects, shipbuilders, marine design offices, acoustic consultants, classification societies, port and maritime regulators, and research organizations involved in measuring, assessing or regulating onboard vessel noise. The corrigendum is used wherever the 1996 edition of ISO 2923 is applied to ensure the corrected text is followed.

Related standards

ISO 2923:1996 (main standard) — to be used together with this corrigendum. Other related acoustics standards and measurement guidance from ISO/TC 43 (for example those addressing transport noise measurement) are often used alongside ISO 2923 for complementary methods and sector-specific requirements.

FAQ

Q: What is this standard?

A: ISO 2923:1996/Cor 1:1997 is a technical corrigendum (one-page correction document) to the international standard ISO 2923:1996, which covers the measurement of noise on board vessels.

Q: What does it cover?

A: The corrigendum provides specific corrections and clarifications to the 1996 edition; the base standard itself defines measurement techniques, instrument requirements, measurement positions and reporting for shipboard noise. Apply the corrigendum together with the main standard.

Q: Who typically uses it?

A: Maritime industry professionals — shipbuilders, acoustic consultants, regulatory bodies, classification societies and researchers involved in shipboard noise measurement and compliance testing.

Q: Is it current or superseded?

A: The corrigendum was published on 3 July 1997 and remains the published correction to ISO 2923:1996. The 1996 edition of ISO 2923 has been maintained by ISO (it was reviewed/confirmed in later ISO reviews), and the corrigendum is applied where ISO 2923:1996 is in force. Users should check the latest status of ISO 2923 with the publisher for any further amendments or newer editions.

Q: Is it part of a series?

A: ISO 2923 is a standalone standard within the ISO acoustics portfolio (work of ISO/TC 43/SC 1). It sits alongside other transport- and vehicle-noise standards from ISO for complementary guidance.

Q: What are the key keywords?

A: Acoustics; shipboard noise; ISO 2923; corrigendum; measurement procedures; marine noise testing.
