Overview

SIST EN 62489-1:2010/A2:2018 is a European standard developed by CLC, focusing on electroacoustics and specifically on audio-frequency induction loop systems designed for assisted hearing. This document, aligned with IEC 62489-1:2010/A2:2017, defines precise methods for measuring and specifying the performance of components within these systems. It serves as a key reference for manufacturers, engineers, and stakeholders involved in the design, testing, and implementation of hearing assistance technologies that employ induction loop systems.

This amendment updates the original 2010 standard by incorporating the latest referenced standards, ensuring alignment with current technologies and measurement techniques for system components. The standard is critical for ensuring interoperability, reliability, and performance consistency in audio-frequency induction loop systems that assist people with hearing impairments.

Key Topics

• Performance Measurement Methods
  The standard outlines rigorous procedures for measuring and specifying performance parameters of induction loop components, ensuring standardized and reproducible test results.

• Component Specifications
  Detailed guidance on specifying critical parameters such as magnetic field strength, loop resistance, amplifier characteristics, and connector requirements ensures components meet user needs and system performance targets.

• Updated Normative References
  SIST EN 62489-1:2010/A2:2018 updates references to key international standards, including:

  • IEC 60118-4:2014 on hearing aids and induction loop performance requirements
  • IEC 60268 series on sound system equipment
  • IEC 61938:2013 for multimedia system interoperability
  • IEC 60603-11:1992 covering connector specifications

• Neck Loop Specifications and Testing
  The amendment provides detailed normative guidance for neck loops used by hearing-aid users, including design examples (types 1 and 2), performance metrics, electrical characteristics, and construction recommendations to enhance usability and reliability.

• Measurement Uncertainty and Accuracy
  It references the ISO/IEC Guide 98-3 (GUM 1995) to ensure confidence in measurement processes and standardize uncertainty evaluation throughout testing.

Applications

• Hearing Aid Systems
  Facilitates the design and quality assurance of audio-frequency induction loop systems that transmit sound signals directly to hearing aids, enhancing communication accessibility in public venues such as theaters, lecture halls, airports, and places of worship.

• Assistive Listening Devices (ALDs)
  Supports the development and verification of devices like neck loops and portable induction loops that improve hearing aid user experience by providing better audio clarity and signal quality.

• Public Address and Audio Systems
  Ensures integration of induction loop systems with general public audio systems by specifying electromagnetic field strength and compatibility requirements.

• Product Development and Certification
  Provides manufacturers with clear criteria for component performance testing, enabling compliance with European regulations and facilitating product certification.
