Overview
SIST EN 61669:2016/A1:2025 Electroacoustics – Measurement of Real-Ear Acoustical Performance Characteristics of Hearing Aids is the European amendment aligning with IEC 61669:2015/AMD1:2025. Published by the European Committee for Electrotechnical Standardization (CLC), this standard specifies methods for accurately measuring the acoustical performance of hearing aids fitted in a real human ear. The amendment aims to ensure consistent and reliable real-ear measurements, supporting the evaluation and adjustment of hearing aid devices across European and international markets.
This standard is essential for professionals in audiology, hearing aid manufacturers, and electroacoustic laboratories to ensure that hearing aids deliver optimal and verifiable performance for individuals with hearing loss.
Key Topics
SIST EN 61669:2016/A1:2025 focuses on:
- Standardized measurement procedures: Outlines requirements for testing the acoustical characteristics of hearing aids when worn by users, providing repeatable and comparable data.
- Real-ear measurements (REM): Emphasizes the importance of actual ear canal sound pressure level (SPL) measurements, as opposed to test-box assessments, for characterizing real-world device performance.
- Update and corrections: Replaces and clarifies equations related to real-ear calculations, including methods for estimating ear canal SPL and correcting audiograms obtained with insert earphones and various types of earmoulds.
- Normative references: Draws on related IEC and ISO standards to ensure coherence with international best practices.
- Compliance requirements: Establishes criteria for the implementation timeline and withdrawal of conflicting national standards, ensuring uniform adoption across European countries.
Applications
Implementation of SIST EN 61669:2016/A1:2025 offers practical value in several areas:
- Fitting and verification: Provides audiologists and hearing aid professionals with methodologies to accurately fit and verify devices based on the individual user’s real-ear acoustical response.
- Product testing: Enables manufacturers to test and document hearing aid performance under standardized conditions, supporting product development and market approvals.
- Quality assurance: Ensures consistent and high-quality performance across various hearing aid models and brands, enhancing user outcomes and satisfaction.
- Conformance demonstration: Facilitates regulatory and clinical documentation, demonstrating compliance with European and international requirements.
- Research and development: Supports ongoing innovation in hearing aid technology by providing a clear framework for objective acoustical measurement.
