Electroacoustics - Hearing aids - Part 0: Measurement of the performance characteristics of hearing aids
SIST EN IEC 60118-0:2024

IEC 60118-0:2022 gives recommendations for the measurement of the performance characteristics of air conduction hearing aids measured with an acoustic coupler or occluded ear simulator. This document is applicable to the measurement and evaluation of the electroacoustical characteristics of hearing aids, for example for type testing and manufacturer data sheets. This document is also applicable for the measurement of the performance characteristics of hearing aids for production, supply and delivery quality-assurance purposes. The measurement results obtained by the methods specified in this document will express the performance under conditions of the measurement and can deviate substantially from the performance of the hearing aid under actual conditions of use. This document primarily uses an acoustic coupler according to IEC 60318-5 which is only intended for loading a hearing aid with specified acoustic impedance and is not intended to reproduce the sound pressure in a person's ear. For measurements reflecting the output level in the normal human ear the occluded ear simulator according to IEC 60318-4 can be used. For extended high-frequency measurements and for deep insert hearing aids, the acoustic coupler according to IEC 60318-8 can be used. This document also covers measurement of hearing aids with non-acoustic inputs, such as wireless, inductive or electrical input. This document does not cover the measurement of hearing aids for simulated in situ working conditions, for which IEC 60118-8 can be applied. This document does not cover the measurement of hearing aids under typical user settings and using a speech-like signal, for which IEC 60118-15 can be applied. IEC 60118-0:2022 merges and updates the methods previously described in IEC 60118-0:2015 and IEC 60118-7:2005. It cancels and replaces the third edition of IEC 60118-0 published in 2015. This edition constitutes a technical revision. Measurements for quality control as described in IEC 60118-7:2005 can be found in Clause 10 of this document. This edition includes the following significant technical changes with respect to previous editions: a) the default use of an acoustic coupler according to IEC 60318-5, b) addition of the optional use of an occluded ear simulator according to IEC 60318-4, c) addition of the optional use of an acoustic coupler according to IEC 60318-8 (new standard based on IEC TS 62886) when information about the response above 8 kHz is needed, or the optional use of the acoustic coupler according to IEC 60318-8 for deep insert hearing aids, d) the addition of measurements of the performance of hearing aids for production, supply and delivery quality assurance purposes, e) corrected and updated measurement configuration and methods, adding the use of a sequential measurement as preferred configuration, f) updated and expanded measurement procedures for the non-acoustic inputs of the hearing aid.

Electroacoustics - Simulators of human head and ear - Part 7: Head and torso simulator for the measurement of sound sources close to the ear
SIST EN IEC 60318-7:2023

This part of IEC 60318 describes a head and torso simulator, or manikin, intended for the measurement of sound sources placed close to the ear in the frequency range from 100 Hz to 16 000 Hz. The manikin described in this part of IEC 60318 is intended for airborne acoustic measurements only. It is not suitable for measurements which depend upon vibration transmission paths such as bone conduction, or for measurements requiring the simulation of bone or tissue. This document specifies the manikin in terms of both its geometrical dimensions and its acoustical properties. For conformance with this document, a manikin shall be compliant with both sets of specifications.

Electroacoustics - Simulators of human head and ear - Part 8: Acoustic coupler for high-frequency measurements of hearing aids and earphones coupled to the ear by means of ear inserts
SIST EN IEC 60318-8:2022

IEC 60318-8:2022 describes an acoustic coupler for loading a hearing aid or insert earphone with a specified acoustic impedance when testing its acoustic performance, in the frequency range up to 16 kHz. It is suitable for air-conduction hearing aids and earphones, coupled to the ear by means of ear inserts, earmoulds or similar devices. The acoustic coupler does not simulate the human ear. However, it has an effective volume of only 0,4 cm3, which is small enough not to produce significant resonances in the coupler in the frequency range below 16 kHz. Therefore, it will load the earphone with a known acoustic impedance, which allows repeatable measurements with low uncertainty to be obtained on earphones used in extended high-frequency audiometry.

This document defines the characteristics to be specified by the manufacturer, specifies minimum mandatory functions for two types of instruments and provides performance specifications applicable to both instrument types. This document describes methods to be used to demonstrate conformance with the specifications in this document and guidance on methods for periodic calibration. The purpose of this document is to ensure that measurements made under comparable test conditions with different instruments complying with this document will be consistent. Instruments can provide a measurement function not specifically within the scope of this document and still comply with the relevant requirements of this document for the functions that are within the scope. This document is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches. IEC 606045-6:2022 cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the nominal test frequency used in DPOAE is now defined as the higher of the two frequencies, f2; b) the permitted deviation of the stimulus signal for TEOAE has been specified; c) the frequency range for DPOAE stimulus signals has been redefined, d) the stimulus level requirements for TEOAE have been redefined; e) the stimulus level requirements for DPOAE have been redefined; f) the harmonic distortion requirements for DPOAE have been redefined; g) a minimum measurement range for DPOAE has been added.

Electroacoustics - Hearing aids - Part 16: Definition and verification of hearing aid features
SIST EN IEC 60118-16:2022

This part of IEC 60118 gives definitions for common hearing aid features such as noise reduction or feedback reduction, etc. Only acoustical inputs are considered. Binaural features are currently not covered in this document. In addition, measurement procedures are described to verify hearing aid features. The objective is not to evaluate the performance of features but to verify their existence and functionality. Furthermore, definitions and procedures are kept as general as possible so that this document can be applied to various types of hearing aids, e.g. air conduction hearing aids or bone conduction hearing aids. To this end, the general definition for hearing aid of IEC 60118-0:2015 is adopted, and this document does not refer to any specific ear simulator or acoustic coupler but uses a general definition of a coupler. However, if a general view is not applicable or leads to unclear or complex wording, the situation for an air conduction hearing aid is considered, only. Nevertheless, in Clause 4, an explanation is given on how this document can be applied to hearing aids which do not use air conduction.
