Overview

SIST EN ISO 389-3:2016/oprA1:2020, titled Acoustics - Reference zero for the calibration of audiometric equipment - Part 3: Reference equivalent threshold vibratory force levels for pure tones and bone vibrators - Amendment 1 (ISO 389-3:2016/DAM 1:2020), is a key international standard developed by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN). This amendment focuses on refining the calibration benchmarks used for audiometric devices, especially concerning pure tone and bone vibrator measurements.

The standard establishes reference equivalent threshold vibratory force levels (RETVFLs) that serve as the baseline zero for calibrating bone conduction audiometric equipment. By ensuring consistent and accurate calibration baselines, EN ISO 389-3 supports reliable diagnosis and assessment of hearing capabilities through bone conduction testing.

Key Topics

• Calibration of Audiometric Equipment
  Establishes precise reference zero values crucial for reliable and repeatable audiometric bone conduction measurements.

• Reference Equivalent Threshold Vibratory Force Levels (RETVFLs)
  Defines RETVFLs across standard frequencies to ensure uniform calibration for pure tone stimuli delivered via bone vibrators.

• Bone Vibrators and Pure Tones
  Provides standardized values specifically for pure tone audiometry via bone conduction, a fundamental method in audiological evaluations.

• Technical Update on 4 kHz Frequency
  Amendment 1 acknowledges emerging research suggesting a possible correction needed for the RETVFL at 4 kHz, indicating ongoing efforts to refine accuracy. However, it notes that there is currently insufficient data for definitive value changes.

• International Collaboration and Standards Maintenance
  Prepared by ISO/TC 43 on Acoustics, the document reflects global consensus and follows ISO/IEC directives and procedures. It also addresses intellectual property considerations related to the standard.

Applications

• Audiology Clinics and Hearing Testing Laboratories
  Enables accurate calibration of bone conduction audiometers, essential for diagnosing conductive hearing loss and differentiating sensorineural hearing impairments.

• Manufacturers of Audiometric Equipment
  Provides internationally accepted reference values needed to design and calibrate bone vibrator systems and pure tone stimuli generators according to global best practices.

• Occupational Health and Safety Testing
  Ensures hearing assessment instrumentation used in workplace noise exposure evaluations are correctly calibrated for bone conduction thresholds.

• Research and Development in Hearing Science
  Offers a reliable standard base for studies involving bone conduction hearing mechanisms and audiometer performance verification.

Related Standards

• EN ISO 389 Series
  Covers other parts providing reference zeros for air conduction audiometry, calibration guidance, and general audiometric equipment calibration principles.

• ISO 8253 Series
  Deals with audiometric testing procedures, complementing the calibration reference values from ISO 389-3.

• IEC 60601-1
  Pertains to the safety and electromagnetic compatibility of medical electrical equipment, relevant for audiometric devices.

• ISO/IEC Directives
  Describes the processes and editorial rules followed in drafting and maintaining ISO standards.
