气导助听器的电磁兼容试验方法解析

Analysis of electromagnetic compatibility test methods for air-conduction hearing aids

介绍了气导助听器电磁兼容抗扰度的要求和试验方法,详细阐述了助听器的临近者兼容性和使用者兼容性2种情况下的输入相关干扰电平的测试方法,解决了测试中易混淆的问题,并通过比较国内、国际助听器的电磁兼容标准差异给出了标准修订及产品设计、监管建议。

The requirements and test methods for the electromagnetic compatibility(EMC)immunity of air-conducted hearing aids were introduced.The test methods for the input-related interference levels were elaborated in the two cases of proximity compatibility and user compatibility of hearing aids,and the confusing problems in the tests were solved.Recommendations for the revision of standards and for product design and regulation were given by comparing international and China's EMC standards for hearing aids.
