To determine the effectiveness of objective statistical detection in CAEP testing to evaluate audibility in young infants with sensorineural hearing loss.
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.
Participants were 18 infants with confirmed sensorineural hearing loss.
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.
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.
确定客观统计检测在 CAEP 测试中评估感觉神经性听力损失的婴幼儿可听度的有效性。
当一组听力受损的婴儿接受或不接受助听时，使用基于语音的刺激进行 CAEP 记录，并在三个呈现水平（55、65 或 75 dB SPL）下进行。后来获得的行为听力图被用作评估自动检测 CAEP 反应存在/缺失准确性的金标准。
参与者为 18 名确诊为感觉神经性听力损失的婴儿。
更高的感觉水平导致更多的 CAEP 反应被检测到。在助听条件下检测到的 CAEP 波形比在未助听条件下多。
我们的结果表明，由自动统计标准定义的 CAEP 反应的存在/缺失在显示放大提供的感觉水平增加是否足以到达皮层时是有效的。从与助听测试相比未助听测试时皮层检测的显著增加可以明显看出这一点。
