目的：利用HEARLab （TM）研究伴有和不伴有模拟传导性听力障碍的正常听力听者的强制性皮层听觉诱发电位（CAEPs）的检测和分化。设计：从24名正常听力的成年人中获得声场caep，戴和不戴耳塞，使用三种自然语音（/m/， /g/和/t/），分别为55、65和75 dB SPL。结果：除最低呈现水平外，反应检测良好；然而，对于个别听众来说，波形的区分通常很差。结论：使用HEARLab的刺激和分析方案，波形分化相对较差，特别是在低呈现水平时。
Objective: The aim was to investigate detection and differentiation of obligatory cortical auditory evoked potentials (CAEPs) in normal-hearing listeners with and without a simulated conductive hearing impairment using the HEARLab (TM).Design: Sound field CAEPs were obtained from 24 normal-hearing adults, with and without earplugs, using three natural speech sounds (/m/, /g/, and /t/) presented at 55, 65, and 75 dB SPL.Results: Response detection was good except for the lowest presentation level; however, differentiation of waveforms was generally poor for individual listeners.Conclusions: Waveform differentiation was relatively poor, especially at low presentation levels, using the HEARLab's stimulus and analysis protocol.
