电反应测听(electrieal response audiometry,ERA)声音刺激引起的听觉器系统的生物电变化,称为听觉诱发电位(auditory evoked potential),测定这种电位变化以了解听觉系统神经径路的方法,即称为电反应测听法。电反应测听又可分为耳蜗、脑干诱发层位和皮套诱发电位,以脑干诱发的位(brainstem evoked potential)最为常用。它由外界声刺激(60—70分贝)诱发7个波形,来了解蜗神经、耳蜗核、上橄榄核、外侧丘系、下丘核、内膝状体和丘脑皮层昕放射的传导功能,可以用来客观测听.因此对不合作的儿童、昏迷者的听觉功能了解有帮助,也可
Electroal response audiometry (ERA) The bioelectrical changes of the auditory system caused by the sound stimulation, called the auditory evoked potential, and the method of measuring this potential change to understand the auditory system’s neural pathways, Measurement method for the electrical reaction. Electro-responsive audiometry can be divided into cochlear, brainstem-inducing layers and holsome evoked potentials, most commonly used as brainstem evoked potentials. It stimulated by external acoustic stimulation (60-70 decibels) induced seven waveforms to understand the cochlear nerve, cochlear nucleus, the superior olivary nucleus, lateral ciliary system, inferior colliculus, geniculate and thalamic cortex Shin radiation transmission function, you can Used to objectively listen to. So for children who do not cooperate, coma who have the understanding of the auditory function may also be
