ANSI S3.22 Criteria for Hearing Protection Devices Laboratory Testing Service Provided by Eurolab

ANSI S3.22 is a standard developed by the American National Standards Institute (ANSI) to specify the criteria for testing hearing protection devices (HPDs). The standard provides guidelines for evaluating the effectiveness of HPDs in reducing sound levels and preventing noise-induced hearing loss.

International and National Standards

The ANSI S3.22 standard is based on international standards, including:

  • ISO 4869:2004(E) - Acoustics -- Hearing protectors -- Part 1: Subjective method for measuring the sound attenuation of ear muffs

  • ISO 11991:2016(E) - Acoustics -- Hearing protectors -- Part 2: Engineering method for calculating the effective A-weighted sound pressure level reduction of ear muffs and inserts

  • ASTM F963-12 Standard Consumer Safety Specification for Toy Safety

    • The standard is also aligned with national standards, such as:

  • EN 352-1:2018 - Personal hearing protectors -- Part 1: Protective devices against solid and liquid particles

  • TSE EN 352-1:2018 - Binaer koruyucu donanımların tarama ve kontrolü için bir standart

    • Standard Development Organizations

    The ANSI S3.22 standard is developed by the Acoustical Society of America (ASA) in collaboration with other standard development organizations, including:

  • International Organization for Standardization (ISO)

  • American National Standards Institute (ANSI)

  • European Committee for Standardization (CEN)

    • Evolution and Update of Standards

    Standards evolve over time to reflect changes in technology, science, and societal needs. The ANSI S3.22 standard has undergone several revisions since its initial publication in 1989.

    Standard Numbers and Scope

    The relevant standard numbers and their scope are:

  • ISO 4869-1:2004(E) - Acoustics -- Hearing protectors -- Part 1: Subjective method for measuring the sound attenuation of ear muffs

  • ISO 11991:2016(E) - Acoustics -- Hearing protectors -- Part 2: Engineering method for calculating the effective A-weighted sound pressure level reduction of ear muffs and inserts

  • ASTM F963-12 Standard Consumer Safety Specification for Toy Safety

  • Temperature (20C 5C)

  • Humidity (50 10)

  • Pressure (1013 mbar 13 mbar)

    • Sample Preparation Procedures

    Samples are prepared according to the manufacturers instructions and in accordance with the standard.

    Testing Parameters and Conditions

    The following parameters and conditions are tested:

  • Sound pressure level

  • Frequency response

  • Insertion loss

    • Test Results and Evaluation

    Test results are evaluated against established criteria, including:

  • Pass/fail criteria

  • Performance limits

    • Test Reports and Certificates

    Test reports and certificates are issued to manufacturers and suppliers of hearing protection devices.

    Conclusion

    The ANSI S3.22 standard provides a framework for ensuring the effectiveness and safety of hearing protection devices through regular testing and evaluation. Manufacturers and suppliers must comply with the standard to ensure compliance with regulatory requirements and protect users from noise-induced hearing loss.
