Portable multimedia equipment - Determination of battery duration - Part 2: Headphones and earphones with active noise-cancelling functions
IEC 63296-2:2023 is applicable to active acoustic noise-cancelling headphones and earphones that have the function of reducing the ambient noise heard by the user by the level of the output sound from the transducer, which is generated by the ambient noise detection microphone and the noise reduction signal processing circuit. This document covers headphones and earphones to be worn over-the-ear or in-ear, all of which are referred to as "headphones" in this document. This document specifies the terms and definitions relating to battery duration of this type of headphones and the measurement and evaluation methods. The noise-detection microphones are mounted in the body, on the surface, or on an accessory of the headphones. Signal-processing circuits are analogue and digital electronic circuits. This document does not deal with equipment intended for hearing protection. It is also not applicable to music players, recorders, etc. that have a noise-cancelling function. The battery duration measurement methods can be applied to headphones having no active noise-cancelling function.

Matériel multimédia portable - Détermination de la durée des batteries - Partie 2: Casques et écouteurs avec fonctions de réduction de bruit active
L'IEC 63296-2:2023 s'applique aux casques et écouteurs à réduction du bruit acoustique active dont la fonction est de réduire le bruit ambiant entendu par l'utilisateur en agissant sur le niveau du son obtenu en sortie du transducteur qui est généré par le microphone de détection du bruit ambiant et le circuit de traitement du signal de réduction du bruit. Le présent document couvre les casques et les écouteurs supra-auriculaires et intra‑auriculaires, qui sont tous désignés par le terme "casques" dans le présent document. Le présent document spécifie les termes et définitions qui concernent la durée des batteries de ce type de casques ainsi que les méthodes de mesurage et d'évaluation. Les microphones de détection du bruit sont montés dans le corps, à la surface ou sur un accessoire des casques. Les circuits de traitement du signal sont des circuits électroniques analogiques et numériques. Le présent document ne traite pas des matériels destinés à la protection auditive. Il ne s'applique pas non plus aux lecteurs de musique, aux enregistreurs, etc. qui possèdent une fonction de réduction du bruit. Les méthodes de mesurage de la durée des batteries peuvent être appliquées aux casques qui n'ont pas de fonction de réduction de bruit active.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
