Sound system equipment - Electroacoustic transducers - Measurement of suspension parts (IEC 62459:2010)
EN 62459:2011

This International Standard applies to the suspension parts of electroacoustic transducers (for example, loudspeakers). It defines the parameters and measurement method to determine the properties of suspension parts like spiders, surrounds, diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore, this method is intended to improve the correlation of measurements between suspension-part manufacturers and loudspeaker manufacturers. The measurement methods provide parameters based on linear and nonlinear modelling of the suspension part and uses both static and dynamic techniques.

a) The upper frequency limit of 40 MHz has been removed.
b) Hydrophone sensitivity definitions have been changed to recognize sensitivities as complex-valued quantities.
c) Procedures to determine the effective hydrophone size have been changed according to the rationale outlined in Annex B.
d) Requirements on the frequencies for which the effective hydrophone size shall be provided have been changed to achieve practicality for increased frequency bands.

Electroacoustics - Simulators of human head and ear - Part 7: Head and torso simulator for the measurement of sound sources close to the ear (IEC 60318-7:2022)
EN IEC 60318-7:2022

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 highfrequency measurements of hearing aids and earphones coupled to the ear by means of ear inserts (IEC 60318-8:2022)
EN IEC 60318-8:2022

This part of IEC 60318 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.

Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields (IEC 62127-1:2022)
EN IEC 62127-1:2022

This part of IEC 62127 specifies methods of use of calibrated hydrophones for the
measurement in liquids of acoustic fields generated by ultrasonic medical equipment including
bandwidth criteria and calibration frequency range requirements in dependence on the spectral
content of the fields to be characterized.
This document:
– defines a group of acoustic parameters that can be measured on a physically sound basis;
– defines a second group of parameters that can be derived under certain assumptions from
these measurements, and called derived intensity parameters;
– defines a measurement procedure that can be used for the determination of acoustic
pressure parameters;
– defines the conditions under which the measurements of acoustic parameters can be made
using calibrated hydrophones;
– defines procedures for correcting for limitations caused by the use of hydrophones with
finite bandwidth and finite active element size, and for estimating the corresponding
uncertainties.
NOTE 1 Throughout this document, SI units are used. In the specification of certain parameters, such as beam
areas and intensities, it can be convenient to use decimal multiples or submultiples. For example, beam area is
likely to be specified in cm2 and intensities in W/cm2 or mW/cm2.
NOTE 2 The hydrophone as defined can be of a piezoelectric or an optic type.

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.

Electroacoustics - Audiometric equipment - Part 6: Instruments for the measurement of otoacoustic emissions (IEC 60645-6:2022)
EN IEC 60645-6:2022

This part of IEC 60645 applies to instruments designed primarily for the measurement of
otoacoustic emissions in the human external auditory meatus evoked by acoustic probe stimuli.
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.
