标准摘要
[中文适用范围]： IEC 62489 系列的这一部分适用于辅助听力的音频感应环路系统的组件。只要适用，它也可以应用于用于其他目的@的系统。该标准旨在鼓励准确、统一地表述制造商的规格@，这些规格可以通过标准化测量方法进行验证。它用于型式测试。考虑的组件如下： ?C 放大器； ?C 麦克风； ?其他组件@例如播放设备。本标准不涉及 IEC 60065 适用的 safety@。它还不涉及 EMC（电磁兼容性）和 EMF（人体暴露的电磁场@）。 [外文原描述]： IEC 62489-1:2010 applies to the components of audio-frequency induction-loop systems for assisted hearing. It may also be applied to such systems used for other purposes, as far as it is applicable. This standard is intended to encourage accurate and uniform presentation of manufacturers' specifications, which can be verified by standardized methods of measurement. It is intended for type testing. The components considered are the following: - amplifiers; - microphones; - other components, such as playback equipment. IEC 62489-1:2010 does not deal with safety, for which IEC 60065 applies. It also does not deal with EMC (Electromagnetic compatibility) and EMF (Electromagnetic fields, in the context of human exposure).
