Overview
ISO 8297:1994/Amd 1:2021 is an essential international standard issued by the International Organization for Standardization (ISO) that focuses on acoustics and noise measurement. This amendment updates the engineering method for determining the sound power levels of multisource industrial plants to evaluate sound pressure levels in the environment. It provides refined procedures and references for accurate noise assessment in complex industrial settings with multiple sound sources. This ensures consistent, reliable, and comparable acoustic data for environmental noise control and regulatory compliance.
Key Topics
Measurement of Sound Power Levels
The standard outlines procedures to assess the total sound power output generated by industrial plants consisting of multiple noise sources.Engineering Method Enhancements
Amendment 1 updates references to current ISO and IEC standards to improve accuracy and instrumentation requirements, including:- Transition from older references (e.g., ISO 2204) to ISO 12001 for machinery noise test codes
- Incorporation of IEC 61672-1 and IEC 61260-1 standards for Class 1 sound level meters and filters
- Use of ISO 9613-1 for calculating sound attenuation due to atmospheric absorption
Instrumentation Requirements
The amendment mandates that all measurement equipment-microphones, cables, windscreens, and recording devices-must comply with Class 1 metrological standards to ensure high precision.Analytical Calculations
Detailed formulas and correction factors for calculating area-related sound power corrections and sound pressure level reductions during propagation are provided.Updated Normative References
The document incorporates the latest editions of standards relevant to acoustics measurements, signal processing, and environmental noise description, improving accuracy and technical relevance.
Applications
Industrial Noise Assessment
This standard is vital for environmental engineers and acousticians evaluating noise emissions from factories, plants, and large-scale industrial facilities with multiple noise sources.Regulatory Compliance
Governments and environmental regulatory bodies rely on ISO 8297:1994/Amd 1:2021 for enforcing noise control policies around industrial areas to protect public health.Environmental Impact Studies
Used in environmental impact assessments (EIA) to predict and quantify industrial noise influence on surrounding communities.Noise Mitigation Planning
Helps in designing noise reduction strategies and soundproofing solutions by providing precise sound power data for engineering controls.Acoustic Research and Development
Facilitates scientific studies and development of new acoustic monitoring equipment and methodologies with standardized reference points.

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.
