ISO 266 Acoustics - Preferred Frequencies Laboratory Testing Service: A Comprehensive Guide

ISO 266 is an international standard that outlines the preferred frequencies for acoustical measurements. It was published by the International Organization for Standardization (ISO) in 1997 and has since become a widely adopted standard globally. The standard is used to ensure consistency and accuracy in acoustical measurements, particularly in the fields of noise measurement, sound quality assessment, and psychoacoustics.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 266 testing varies by country. In some jurisdictions, compliance with ISO 266 is mandatory for specific industries or applications. For instance, in the European Union, the use of ISO 266 preferred frequencies is required for noise measurement and assessment under the EUs Environmental Noise Directive.

International and National Standards

The following international and national standards apply to ISO 266 testing:

  • ISO 266:1997 (Acoustics - Preferred frequencies)

  • ASTM E989-12 (Standard Practice for Acoustic Calibration of Microphones)

  • EN 61672-1:2013 (Electroacoustics - Specifications for electroacoustic transducers and the cabinet mounting systems for use in hand-held and free-field measurements of loudspeakers - Part 1: General requirements)

  • TSE ISO 266:2017 (Akustik - İsteğe Bağlı Frekanslar)

    • Standard Development Organizations

    The development of ISO 266 was overseen by Technical Committee TC 43/SC 1, which is responsible for acoustics in the built environment. The committee consists of experts from various countries who contribute to the standards development and revision.

    Evolution of Standards

    Standards evolve over time to reflect advancements in technology and changing regulatory requirements. ISO 266 has undergone revisions since its initial publication in 1997, with the latest version being published in 2010.

    Standard Numbers and Scope

    The following are specific standard numbers and their scope:

  • ISO 266:1997 - Acoustics - Preferred frequencies

    • Scope: Specifies preferred frequencies for acoustical measurements.

  • ASTM E989-12 - Standard Practice for Acoustic Calibration of Microphones

    • Scope: Provides guidelines for acoustic calibration of microphones.

    Industry-Specific Requirements
