本研究的目的是使用声学变化复合体 (ACC) 检查人工耳蜗 (CI) 接受者频率变化检测的神经基质，ACC 是一种由持续刺激中的声学变化引起的皮层听觉诱发电位。对 12 名舌后聋成年 CI 用户进行了心理声学测试和脑电图 (EEG) 记录。刺激是包含不同幅度的向上频率变化的纯音。结果显示，CI用户的频率变化检测阈值（FCDT）为3.79%，变异性较大。 ACC N1’潜伏期与 FCDT 和临床收集的言语感知评分显着相关。结果表明，频率变化引起的 ACC 可以作为评估频率变化检测能力和预测 CI 用户语音感知性能的有用客观工具。
The purpose of this study was to examine neural substrates of frequency change detection in cochlear implant (CI) recipients using the acoustic change complex (ACC), a type of cortical auditory evoked potential elicited by acoustic changes in an ongoing stimulus. A psychoacoustic test and electroencephalographic (EEG) recording were administered in 12 post-lingually deafened adult CI users. The stimuli were pure tones containing different magnitudes of upward frequency changes. Results showed that the frequency change detection threshold (FCDT) was 3.79% in the CI users, with a large variability. The ACC N1’ latency was significantly correlated to the FCDT and the clinically collected speech perception score. The results suggested that the ACC evoked by frequency changes can serve as a useful objective tool in assessing frequency change detection capability and predicting speech perception performance in CI users.
