Comprehensive Guide to IEC 60268-16 Sound System Equipment - Objective Rating of Speech Intelligibility Testing Service Provided by Eurolab

The International Electrotechnical Commission (IEC) Standard 60268-16, Sound system equipment Part 16: Objective rating of speech intelligibility, provides a standardized method for evaluating the intelligibility of speech in sound systems. This standard is widely adopted globally and is considered a benchmark for ensuring that audio equipment meets minimum requirements for clear and intelligible speech reproduction.

Legal and Regulatory Framework

IEC 60268-16 is a fundamental standard that supports various national and international regulations, including those related to audio equipment certification and compliance. For instance:

  • In the European Union (EU), IEC 60268-16 is referenced in the EUs Machinery Directive (2006/42/EC) and the Low Voltage Directive (2014/35/EU).

  • In the United States, IEC 60268-16 is referenced in the Occupational Safety and Health Administration (OSHA) regulations for hearing conservation programs.

  • In Australia, IEC 60268-16 is referenced in the Australian Standard AS/NZS 1269:2005, which deals with safety requirements for hearing protectors.

    • International and National Standards

    IEC 60268-16 is part of a broader series of standards that cover various aspects of audio equipment. Some relevant international and national standards include:

  • IEC 60065: Audio, video and similar electronic apparatus Safety requirements

  • IEC 60945: Maritime navigation and radiocommunication equipment and systems General requirements Radio equipment

  • EN 60268-16 (European Standard): Sound system equipment Part 16: Objective rating of speech intelligibility

    • Standard Development Organizations

    The development and maintenance of IEC 60268-16 are the responsibilities of various standard development organizations, including:

  • International Electrotechnical Commission (IEC)

  • European Committee for Electrotechnical Standardization (CENELEC)

  • Australian Standards

  • Underwriters Laboratories (UL) in the United States

    • Standard Evolution and Updates
