为探讨噪声性听力损失声导抗测试特点，如何运用声导抗有关参数，估计噪声作业人员听力损失程度，为噪声聋诊断提供较为客观的指标。我科最近采用声导抗仪配合听力计，选择测试不同程度噪声性听力损失125例（250耳），现将结果报告如下：1对象和方法1．1对象在对噪声作业人员健
In order to explore the characteristics of noise-induced acoustic impedance testing, how to use the parameters of acoustic impedance to estimate the degree of hearing loss of noise workers and provide objective indexes for noise-deaf diagnosis. Our department recently used acoustic impedance meter with audiometer, choose to test different degrees of hearing loss of noise in 125 cases (250 ears), the results are reported as follows: 1 objects and methods 1.1 objects in noise workers
