摘　　要：电磁辐射抗扰度测量是助听器电磁兼容检测中的重要项目,测量结果以表征助听器抗扰度水平的输入相关干扰电平(IRIL)表示。该文分析了影响助听器辐射抗扰度测量不确定度的各种因素,建立了不确定度评定的数学模型,并最后进行了合成标准不确定度的计算,为电磁兼容实验室的不确定度评定提供了参考。Electromagnetic radiation immunity test is an important item in the electromagnetic compatibility measurements of hearing aids.The measurement result is showed by the input related interference level(IRIL)which is used to manifest the immunity level of hearing aids.This paper analyzed various factors affecting the measurement uncertainty of radiation immunity of hearing aids,and then established the mathematical model of uncertainty and at last the synthetic standard uncertainty was calculated,thus providing a reference for the evaluation of uncertainty report for electromagnetic compatibility laboratory.
