(Main)Portable multimedia equipment - Determination of battery duration - Part 2: Headphones and earphones with active noise-cancelling functions
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.
