IEC TR 63079:2017(E)就旨在传达语音、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、操作和维护提供建议和指导。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频的感应回路系统，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。

IEC TR 63079:2017(E) 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.
