目的：探讨客观统计检测在婴幼儿感音神经性耳聋CAEP检测中的有效性。设计：在三种呈现水平(55、65或75dBSPL)下对基于语音的刺激进行CAEP记录，当一组听力受损婴儿接受或不接受帮助时。后来获得的行为听力图被用作评估自动检测CAEP反应是否存在的准确性的金标准。研究样本：受试者为18名确诊为感音神经性耳聋的婴儿。结果：更高的感觉水平导致更多的当前CAEP反应被检测到。辅助条件下检测到的CAEP波形多于非辅助条件下的。结论：由自动统计标准定义的CAEP反应的存在或不存在，可以有效地显示由放大提供的感觉水平是否足以到达皮层。当比较无辅助测试和辅助测试时，从皮质检测的显著增加可以清楚地看出这一点。
Objective: To determine the effectiveness of objective statistical detection in CAEP testing to evaluate audibility in young infants with sensorineural hearing loss. Design: CAEP recordings to speech-based stimuli were made at three presentation levels (55, 65, or 75 dB SPL) when a group of hearing-impaired infants were either aided or unaided. Later-obtained behavioral audiograms were used as the gold standard against which to evaluate the accuracy of the automatic detection of the presence/absence of CAEP responses. Study sample: Participants were 18 infants with confirmed sensorineural hearing loss. Results: Higher sensation levels led to a greater number of present CAEP responses being detected. More CAEP waveforms were detected in the aided condition than in the unaided condition. Conclusion: Our results suggest that the presence/absence of CAEP responses defined by the automatic statistical criterion was effective in showing whether increased sensation levels provided by amplification were sufficient to reach the cortex. This was clearly apparent from the significant increase in cortical detections when comparing unaided with aided testing.
