标准摘要
[中文适用范围]： 本标准适用于音频频率感应环路系统的组件，用于辅助听力。它也可以适用于用于其他目的的此类系统，只要适用。本标准旨在鼓励准确和统一地呈现制造商的规格，这些规格可以通过标准化的测量方法进行验证。它旨在用于类型测试。考虑的组件包括：放大器；麦克风；其他组件，如播放设备。本标准不涉及安全性，安全性适用IEC 60065。它也不涉及EMC（电磁兼容性）和EMF（电磁场，在人体暴露的背景下）。 [外文原描述]： IEC 62489-1:2010+A1:2014+A2:2017 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). This consolidated version consists of the first edition (2010), its amendment 1 (2014) and its amendment 2 (2017). Therefore, no need to order amendment in addition to this publication.
英文名称Electroacoustics - Audio-frequency induction loop systems for assisted hearing - Part 1: Methods of measuring and specifying the performance of system components
