本文报告了70 db(nHL)短声诱发的38例正常听力耳的听觉中潜伏期反应,分析了其波形、波V、N_a、P_a的潜伏期和振幅。比较声刺激侧和对侧记录的各参数,发现除对侧记录的波V、N_a振幅明显低于声刺激侧外,P_A波振幅和V、N_a、P_a波潜伏期双侧间无显著差异。还讨论了肌源性反应的影响,指出取得可靠反应应注意的事项。 This article reports the auditory latent latency response of 38 normal hearing ears induced by 70 db (nHL) short beacons, and analyzes the latency and amplitude of the waveform, wave V, N_a, and P_a. Comparing the parameters of acoustic stimulation and contralateral recording, it was found that there was no significant difference between the amplitude of P_A wave and the latency of V, N_a, P_a wave except for the amplitudes of V and N_a recorded on the contralateral side. The effects of myogenic reactions were also discussed, pointing out the issues to be aware of for reliable responses.
