阻抗测听不仅能测试耳传导性病变的性质,而且能判断感觉神经性聋的病变部位,包括蜗后病变及中枢病变,在几分钟内,即可获得所需要的全部资料。所有的测验数据,都是客观的。而且测验过程对病人并无损伤。声反射潜伏期的测验是近年来声反射测验的新发展,是以镫骨肌反射为基础,研究一些影响镫骨肌反射的因素。反射潜伏期测验的资料与文献报导的脑干电反应测听所提供的资料很相似。两种测验法都是测量听觉通路神经传导的时间。但反射潜伏期测验的资料中还包含着反射弧的运动部分。声反射潜伏期测验与脑干反应测听相比较,在技术上较简便,测验所需时间也较短,在 Impedance audiometry can not only test the properties of otoconductive lesions, but also determine the lesion sites of sensory nerve deafness, including the cochlear lesion and central lesion, and get all the information you need within minutes. All the test data are objective. And the test process does not damage the patient. Acoustic reflex latency test is a new development of acoustical reflex test in recent years. It is based on the psoraleae reflex, and studies some of the factors that affect the psoas muscle reflex. The data from the Reflex Latency Test are similar to those reported in the literature for brainstem response. Both tests measure the time of nerve conduction in the auditory pathway. But the reflex latency test data also contains the reflex arc movement part. Acoustic reflex latency test and brainstem response audiometry compared to the technical more simple, shorter test time required, in the
