IEC reference coupler for the measurement of hearing aids using earphones coupled to the ear by means of ear inserts

IEC reference coupler for the measurement of hearing aids using earphones coupled to the ear by means of ear inserts

Describes a coupler for loading the earphone with a specified acoustic impedance when determining the physical performance characteristics, in the frequency range 200 Hz to 5 000 Hz, of air-conduction hearing aids using earphones coupled to the ear by means of ear inserts, e.g. ear moulds or similar devices. The use of this coupler does not allow the actual performance of a hearing aid on a person to be obtained. Its use is recommended as a simple and ready means for the exchange of specifications and of physical data on hearing aids.

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

Medical electrical equipment - Part 2-66: Particular requirements for the basic safety and essential performance of hearing aids and hearing aid systems (IEC 60601-2-66:2019)
EN IEC 60601-2-66:2020

EN-IEC 60601-2-66 applies to the BASIC SAFETY of HEARING AIDS and HEARING AID SYSTEMS, hereafter also referred to as ME EQUIPMENT or ME SYSTEM. If a clause or subclause is specifically intended to be applicable to HEARING AIDS only, or to HEARING AID SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to HEARING AIDS and to HEARING AID SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of HEARING AIDS or HEARING AID SYSTEMS within the scope of this document are not covered by specific requirements in this document except in 201.7.9.2 and 201.9.6. ACCESSORIES to HEARING AIDS in the HOME HEALTHCARE ENVIRONMENT (e.g. remote control units, audio streamers, battery chargers, power supplies) can be tested according to the applicable standard, IEC 60065, IEC 60950-1, IEC 62368-1 or other applicable IEC safety standards. Alternatively, the general standard may be applied. HEARING AIDS do not have a MAINS PART intended for connection to AC SUPPLY MAINS. The connection to the SUPPLY MAINS of a HEARING AID SYSTEM is covered by power supply, charger or other types of ACCESSORIES. ACCESSORIES with FUNCTIONAL CONNECTION to a HEARING AID may form a HEARING AID SYSTEM. HEARING AID related ACCESSORIES that are not physically connected to the HEARING AID during NORMAL USE are not considered to be APPLIED PART, because they do not directly contribute to the INTENDED USE of the HEARING AID. Wireless programming interfaces are covered by the applicable standard IEC 60065, IEC 60950-1, IEC 62368-1 or other applicable IEC safety standards. Alternatively, the general standard may be applied. Programming interfaces with wired connection to the HEARING AID are covered by the general standard.

Electroacoustics - Hearing aids - Part 9: Methods of measurement of the performance characteristics of bone conduction hearing aids (IEC 60118-9:2019)
EN IEC 60118-9:2019

This Standard specifies methods for the measurement of bone conduction hearing aid characteristics. The methods described will produce a suitable basis for the exchange of information or for direct comparison of the electroacoustical characteristics of bone conduction hearing aids. These methods are chosen to be practical and reproducible and are based on selected fixed parameters. The results obtained by the methods specified in this document express the performance under the conditions of measurement; however, the performance of the hearing aid under practical conditions of use will depend upon a number of factors (e.g. effective load impedance, environmental conditions, acoustical environment, etc.). This document defines methods of measurement of characteristics of bone conduction hearing aids both for - transcutaneously coupled devices measured on a mechanical coupler, meeting the requirements of IEC 60318-6, and - bone coupled/bone anchored devices measured on a skull simulator.

Electroacoustics - Measurement of real-ear acoustical performance characteristics of hearing aids
EN 61669:2016

This International Standard gives recommendations and requirements for the measurement
and estimation of the real-ear acoustical performance characteristics of air-conduction
hearing aids and for the measurement of certain acoustic properties of the ear related to the
application of hearing aids.
Measurements of real-ear acoustical characteristics of hearing aids which apply non-linear or
analytical processing techniques are valid only for the test signals used and conditions
employed.
The purpose of this standard is to ensure that measurements of real-ear acoustical
performance characteristics of a given hearing aid on a given human ear can be replicated in
other locations with other test equipment.

Electroacoustics - Hearing aids - Measurement of the performance characteristics of hearing aids
EN 60118-0:2015

This part of IEC 60118 gives recommendations for the measurement of the performance
characteristics of air conduction hearing aids based on a free field technique and measured
with an acoustic coupler.
This part of IEC 60118 is applicable to the measurement and evaluation of the
electroacoustical characteristics of hearing aids, for example for type testing and
manufacturer data sheets.
The test results obtained by the methods specified in this part of IEC 60118 will express the
performance under conditions of the test and may deviate substantially from the performance
of the hearing aid under actual conditions of use.
This part of IEC 60118 uses an acoustic coupler according to IEC 60318-5 which is only
intended for loading a hearing aid with a specified acoustic impedance and is not intended to
model the sound pressure in a person’s ear. The use of this acoustic coupler will yield
different results from those obtained using the occluded ear simulator of IEC 60318-4 as used
in former editions of IEC 60118-0.
For the measurement of the performance characteristics of hearing aids for simulated in situ
working conditions, IEC 60118-8 can be used. For measurement of hearing aids under typical
user settings and using a speech-like signal, IEC 60118-15 can be used.
For the measurement of the performance characteristics of hearing aids for production, supply
and delivery quality-assurance purposes, IEC 60118-7 can be used. The frequency range has
been extended to 8 kHz in this part of IEC 60118 as opposed to 5 kHz in IEC 60118-7.
Though the number of measurements covered by this part of IEC 60118 is limited, it is not
intended that all measurements described herein are mandatory.
In cases of custom-made in-the-ear instruments, the data supplied by the manufacturer
applies only to the particular hearing aid being tested.

Electroacoustics - Hearing aids - Part 4: Induction loop systems for hearing aid purposes - System performance requirements
EN 60118-4:2015

This part of IEC 60118 is applicable to audio-frequency induction-loop systems producing an
alternating magnetic field at audio frequencies and intended to provide an input signal for
hearing aids operating with an induction pick-up coil (telecoil). Throughout this standard, it is
assumed that the hearing aids used with it conform to all relevant parts of IEC 60118.
This standard specifies requirements for the field strength in audio-frequency induction loops
for hearing aid purposes, which will give adequate signal-to-noise ratio without overloading
the hearing aid. The standard also specifies the minimum frequency response requirements
for acceptable intelligibility.
Methods for measuring the magnetic field strength are specified, and information is given on
appropriate measuring equipment (see Annex B), information that should be provided to the
operator and users of the system (see Annex C), and other important considerations.
This standard does not specify requirements for loop driver amplifiers or associated
microphone or audio signal sources, which are dealt with in IEC 62489-1, or for the field
strength produced by equipment, such as telephone handsets, within the scope of ITU-T
P.370.
