Overview
ISO 80000-8:2020/Amd 1:2025 is an important amendment to the international standard ISO 80000-8, which deals with quantities and units in the field of acoustics. Published by the International Organization for Standardization (ISO), this amendment ensures the standard remains current with the latest international measurement practices. It brings updates related to normative references and terminology used for acoustic quantities and units, aligning them more closely with the International System of Units (SI).
This standard amendment is crucial for professionals involved in acoustics, audio engineering, noise control, and related disciplines, providing a unified framework for using and interpreting acoustic measurements globally.
Key Topics
Updated Normative References: The amendment revises the normative references section by including the latest edition of the International System of Units (SI), specifically referencing the 9th edition by BIPM (2019). This ensures that the acoustic quantities and units conform to the most recent SI definitions and conventions.
Revised Terminology and Definitions: The amendment modifies the terms and definitions section to clarify that acoustic quantities, their names, symbols, and units are standardized both in the amendment’s Table 1 and according to the SI units. This harmonization helps in maintaining consistency across technical documents and measurement protocols.
Compatibility with ISO/IEC Directives: The document was developed following ISO/IEC editorial and procedural rules, ensuring high quality and international compatibility in standardization processes.
Collaboration with IEC and CEN: The preparation involved joint efforts with the International Electrotechnical Commission (IEC) and the European Committee for Standardization (CEN), reinforcing its relevance across multiple technical sectors including electrotechnical and acoustic standards.
Applications
ISO 80000-8:2020/Amd 1:2025 serves a critical role in various practical contexts:
Acoustic Measurement and Instrumentation
Ensures that acoustic instruments and measurement techniques use internationally recognized quantities and units, promoting accuracy and comparability.Sound Engineering and Noise Control
Offers a standardized vocabulary and measurement framework essential for sound quality assessment, noise pollution management, and regulatory compliance.Research and Development in Acoustics
Facilitates consistent data reporting and interpretation, supporting advances in acoustic technology, environmental acoustics, and psychoacoustics.Education and Technical Training
Provides authoritative reference material for academic curricula and professional training programs in acoustics and related engineering fields.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
