摘要
骨导式助听器属于助听器类的一大分支,由于声音传播路径不同,骨导式助听器电磁兼容性的考察不同于气导式助听器。现行标准中对骨导式助听器的电磁兼容检测方法和指标尚无规定。本文研究了骨导式助听器电磁兼容的要点及检测方法,设计测试流程并对测试结果进行分析,以期对今后的同类产品的质控和检测工作起到技术指导作用。
Bone conduct hearing aids belong to a branch of hearing aids.Because of the different sound transmission paths,the investigation of electromagnetic compatibility of bone-conduct hearing aids is different from that of air-conduct hearing aids.Current standards do not specify the electromagnetic compatibility(EMC)testing methods and acceptance criteria of bone-guided hearing aids.This paper studied the EMC testing methods of bone conduct hearing aids,designed the testing process and analyzed the testing results.
