IEC TR 63079:2017+A1:2018+A2:2020为用于通信语音、音乐和/或其他信号的听觉回路系统（HLS）的设计、规划、安装、测试、操作和维护提供了建议和指南。它主要涉及用于听力增强的HLS，其中信号被传送给配备有磁性拾取线圈的助听器的用户。本文件不适用于使用载波频率的感应回路系统，也不适用于不使用磁感应的用于听力增强目的的其他系统。该合并版本由第一版（2017年）、修正案1（2018年）和修正案2（2020年）组成。因此，除了本出版物之外，没有必要下令进行修订。

IEC TR 63079:2017+A1:2018+A2:2020 gives recommendations for and guidance on the design, planning, installation, testing, operation and maintenance of a hearing-loop system (HLS) intended for communicating speech, music and/or other signals. It is mainly concerned with HLS for hearing enhancement, in which the signals are communicated to users of hearing aids equipped with magnetic pick-up coils. This document does not apply to induction-loop systems which use a carrier frequency, nor to other systems for hearing enhancement purposes which do not use magnetic induction. This consolidated version consists of the first edition (2017), its amendment 1 (2018) and its amendment 2 (2020). Therefore, no need to order amendments in addition to this publication.
