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.

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 applies to hearing aid fitting management (HAFM) services offered by hearing aid professionals (HAP) when providing benefit for their clients. The provision of hearing aids relies on the knowledge and practices of a hearing aid professional, to ensure the proper fitting and adequate service in the interest of the client with hearing loss.
This document specifies general processes of HAFM from the client profile to the follow-up through administering, organising and controlling hearing aid fitting through all stages. It also specifies important preconditions such as education, facilities and systems that are required to ensure proper services.
The focus of this document is the services offered to the majority of adult clients with hearing impairment. It is recognized that certain populations with hearing loss such as children, persons with other disabilities or persons with implantable devices can require services outside the scope of this document. This document generally applies to air conduction hearing aids and for the most part also to bone conduction devices.
Hearing loss can be a consequence of serious medical conditions. Hearing aid professionals are not in a position to diagnose or treat such conditions. When assisting clients seeking hearing rehabilitation without prior medical examination, hearing aid professionals are expected to be observant of symptoms of such conditions and refer to proper medical care.
Further to the main body of the document, which specifies the HAFM requirements and processes, several informative annexes are provided. Appropriate education of hearing aid professionals is vital for exercising HAFM. Annex A defines the competencies required for the HAFM processes. Annex B offers a recommended curriculum for the education of hearing aid professionals. Annex C is an example of an appropriate fitting room. Annex D gives guidance on the referral of clients for medical or other specialist examination and treatment. Annex E is a recommendation for important information to be exchanged with the client during the process of HAFM. Annex F is a comprehensive terminology list offering definitions of the most current terms related to HAFM.
It is the intention that these annexes be helpful to those who wish to deliver HAFM of the highest quality.

This document specifies laboratory methods for measuring the impact sound insulation of floor
assemblies.
The test results can be used to compare the sound insulation properties of building elements, classify
elements according to their sound insulation capabilities, help design building products which require
certain acoustic properties and estimate the in situ performance in complete buildings.
The measurements are performed in laboratory test facilities in which sound transmission via flanking
paths is suppressed. The results of measurements made in accordance with this document are not
applicable directly to the field situation without accounting for other factors affecting sound insulation,
such as flanking transmission, boundary conditions, and loss factor.
A test method is specified that uses the standard tapping machine (see ISO 10140-5:2021, Annex E)
to simulate impact sources like human footsteps when a person is wearing shoes. Alternative test
methods, using a modified tapping machine or a heavy/soft impact source (see ISO 10140-5:2021,
Annex F) to simulate impact sources with strong low frequency components, such as human footsteps
(bare feet) or children jumping, are also specified.
This document is applicable to all types of floors (whether heavyweight or lightweight) with all types of
floor coverings. The test methods apply only to laboratory measurements.

IEC 61828:2020 - provides definitions for the transmitted field characteristics of focusing and nonfocusing transducers for applications in medical ultrasound; - relates these definitions to theoretical descriptions, design, and measurement of the transmitted fields of focusing transducers; - gives measurement methods for obtaining defined field characteristics of focusing and nonfocusing transducers; - specifies beam axis alignment methods appropriate for focusing and nonfocusing transducers. IEC 61828:2021 relates to focusing ultrasonic transducers operating in the frequency range appropriate to medical ultrasound (0,5 MHz to 40 MHz) for both therapeutic and diagnostic applications. It shows how the characteristics of the transmitted field of transducers can be described from the point of view of design, as well as measured by someone with no prior knowledge of the construction details of a particular device. The transmitted ultrasound field for a specified excitation is measured by a hydrophone in either a standard test medium (for example, water) or in a given medium. This document applies only to media where the field behaviour is essentially like that in a fluid (i.e. where the influence of shear waves and elastic anisotropy is small), including soft tissues and tissue-mimicking gels. Any aspects of the field that affect their theoretical description or are important in design are also included. These definitions would have use in scientific communications, system design and description of the performance and safety of systems using these devices. IEC 61828:2021 incorporates definitions from other related standards where possible, and supplies more specific terminology, both for defining focusing characteristics and for providing a basis for measurement of these characteristics. IEC 61828:2021 cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Clause 6 on Measurement procedures has been replaced by Clause 6: "Acoustic field measurement: equipment" and Clause 7: "Measurement procedure" and related definitions. b) Reorganization of definitions and measurement section to accommodate specific sets of measurements for focusing, nonlinearity, beam axis alignment, beam area, beam maximum, numerical projection, plane wave, high intensity therapeutic ultrasound, multiple sources, spatial impulse response and compound plane waves. Clause 3 has been moved to Annex B. c) The normative references have been updated and the Bibliography has been expanded from 8 to 40 references. d) Twelve figures have been updated and seven new figures (B.1, B.3, B.7, B.10, B.11, B.12, B.13, B.14) have been added to facilitate measurements and be consistent with measurement terminology. e) New measurements have been added for time delays, arrays, plane waves and spatial impulse response. f) Annex A has been expanded to provide general guidance on pulsed waves, system responses, focusing gains and minimum beamwidth estimation. g) New annexes have been added: • Annex B (informative) Rationale for focusing and nonfocusing definitions • Annex E (informative) Uncertainties; • Annex F (informative) Transducer and hydrophone positioning systems; •

This document specifies two tyres intended to serve as reference tyres when using the close-proximity (CPX) method specified in ISO 11819-2. The CPX method is a method for evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. This method ideally requires the use of standardized tyres, which have noise characteristics that are broadly representative of the effect of road surfaces on the noise emission of passenger car and heavy vehicle tyres. However, such tyres are not specified in ISO 11819-2. This document serves to specify these standardized tyres.

This document specifies a laboratory substitution method to determine the insertion loss without flow
of ducted, mainly absorbent, circular and rectangular silencers, as well as other duct elements for use
in ventilating and air-conditioning systems.
NOTE Laboratory measurement procedures for ducted silencers with superimposed flow are described in
ISO 7235[5].
This document is applicable to silencers where the design velocity does not exceed 15 m/s. As the
method does not include self-generated flow noise, this document is not suitable for tests on silencers
where this type of noise is of great importance for the evaluation of the silencer performance. As most
silencers, particularly in offices and dwelling, have design velocities below 15 m/s, this document can
often be a cost-efficient alternative to ISO 7235[5].
The insertion loss determined according to this document in a laboratory is not necessarily the same
as the insertion loss obtained in an installation in the field. Different sound and flow fields in the duct
yield different results. In this document, the sound field is dominated by plane wave modes. Due to the
use of regular test ducts, the results can include some flanking transmission via structural vibrations
in the duct walls that sets an upper limit to the insertion loss that can be determined.
This document is intended to be used for circular silencers with diameters of 80 mm to 2 000 mm or for
rectangular silencers with cross-sectional areas within the same range.
