Electroacoustics - Audio-frequency induction loop systems for assisted hearing - Part 1: Methods of measuring and specifying the performance of system components
电声 - 用于辅助听觉的音频感应回路系统 - 第1部分:测量和指定系统组件性能的方法
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).
