标准摘要
[中文适用范围]: “IEC 60118 的这一部分原则上涵盖了助听器的所有相关 EMC 现象。目前不知道 RF 发射和静电放电等 EMC 现象@是否是与助听器相关的重大问题,因此不予处理。基于助听器对源于工作频率范围 0@8 GHz 至 0@96 GHz 和 1@4 的数字无线设备的高频电磁场的抗扰度GHz 至 2@48 GHz 目前被确定为与助听器相关的唯一相关 EMC 现象。IEC 60118 这部分的未来版本可能会添加针对其他频段@的测试,因为它们会更普遍使用。IEC 61000-4-3 是对助听器进行相关 EMC 测试的基础。测量方法和验收水平在 IEC 60118 本部分中进行了描述。出于 IEC 60118@ 本部分的目的,定义了助听器的两个抗扰等级(见 3.1)。供他们使用。 “旁观者兼容”确保助听器可在数字无线设备在助听器佩戴者附近运行的环境中使用。 “用户兼容”助听器确保当佩戴者在其自己的受助耳处使用数字无线设备时助听器可用。本标准没有给出非声学输出的助听器以及通过电缆连接到其他设备的助听器的测量方法。” [外文原描述]: IEC 60118-13:2011 in principle covers all relevant EMC phenomena for hearing aids. Hearing aid immunity to high frequency electromagnetic fields originating from digital wireless devices operating in the frequency ranges 0,8 GHz to 0,96 GHz and 1,4 GHz to 2,48 GHz is currently identified as the only relevant EMC phenomenon regarding hearing aids. Future editions of this part of IEC 60118 may add tests for other frequency bands, as they come into more common use. IEC 61000-4-3 is the basis for relevant EMC tests to be conducted on hearing aids. Measurement methods and acceptance levels are described in this part of IEC 60118. This third edition cancels and replaces the second edition published in 2004 and constitutes a technical revision. It introduces a new set of requirements for use of hearing aids with mobile phones.
