标准范围

IEC 63296-2:20 23适用于主动声学降噪耳机和耳机，其具有通过换能器的输出声音的电平来降低用户听到的环境噪声的功能，该输出声音由环境噪声检测麦克风和降噪信号处理电路产生。本文件涵盖要戴在耳朵上或入耳式的头戴式耳机和耳机，所有这些在本文件中都被称为“头戴式耳机”。本文件规定了与此类耳机的电池持续时间相关的术语和定义以及测量和评估方法。噪声检测麦克风安装在耳机的主体、表面或附件上。信号处理电路是模拟和数字电子电路。本文件不涉及用于听力保护的设备。它也不适用于具有噪声消除功能的音乐播放器、录音机等。电池持续时间测量方法可以应用于不具有主动噪声消除功能的耳机。

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.
