本文比较了噪声性耳聋组与对照组听力曲线的形态特征,结果表明噪声组听力曲线双耳对称性分布和高频段“V”、“U”型凹陷高于对照组,而高频段倾斜形下降两组无差异。初步认为噪声性耳聋的听力曲线应是双侧对称性的感音性听力下降,高频段呈“V”、“U”型凹陷具有一定的诊断意义。
In this paper, we compared the morphological characteristics of hearing loss in noise-induced deafness group and control group. The results showed that the distribution of binaural symmetry of the hearing curve of noise group was higher than that of the control group, while the high frequency band was declined No difference between the two groups. It is preliminarily believed that the hearing curve of noise-induced deafness should be sensory hearing with bilateral symmetry, and the high frequency band is “V”. The depression of “U” type has some diagnostic significance.
