目的研究正常新生儿和新生儿重症监护病房（NICU）出院后通过听力筛查和DPOAE随访的正常新生儿短声和短纯音听性脑干反应（TB-ABR）气导和骨导的正常阈值和潜伏期。本研究采用了诱发电位系统（Vivosonic Integrity™），该系统结合了蓝牙电隔离和卡尔曼加权自适应处理以提高信噪比。结果与其他已发表的数据进行了比较。145名通过瞬态诱发耳声发射（OAE）或自动ABR两阶段听力筛查的婴儿在70 dB nHL和阈值TB-ABR下进行了评估。采用频率在500至4000 Hz之间的短纯音进行空气和骨传导ABR测试，使用指定的阶梯阈值搜索来建立阈值水平和波V峰值延迟。使用TB-ABR的中位气导听阈范围为0-20 dB nHL，取决于刺激频率。所有频率的骨导阈值中位数均为10 dB nHL，所有频率的气骨间隙中位数均为0 dB。左右耳听阈差异无统计学意义，听阈与听力损失危险因素、种族、性别无显著关系。年龄越大，空气传导潜伏期越短。与以前的研究相比，平均空气传导阈值在略低（更好）的水平，而骨传导水平在2000 Hz和500 Hz更高。在500 Hz下的延迟值比使用其他仪器的先前研究更长。睡眠状态不影响空气或骨传导阈值。本研究证明，与之前的婴儿研究相比，空气传导的V波阈值略好。当前研究中发现的差异虽然具有统计学显著性，但均在10 dB的测试步长范围内。这表明，使用卡尔曼加权软件获得的阈值响应范围内的其他已发表的研究使用传统的信号平均，给定步长的限制。不同的睡眠状态不会对控制产生不利影响。
To study normative thresholds and latencies for click and tone-burst auditory brainstem response (TB-ABR) for air and bone conduction in normal infants and those discharged from neonatal intensive care units (NICU), who passed newborn hearing screening and follow-up DPOAE. An evoked potential system (Vivosonic Integrity™) that incorporates Bluetooth electrical isolation and Kalman-weighted adaptive processing to improve signal to noise ratios was employed for this study. Results were compared with other published data. One hundred forty-five infants who passed two-stage hearing screening with transient-evoked otoacoustic emission (OAE) or automated ABR were assessed with clicks at 70 dB nHL and threshold TB-ABR. Tone-bursts at frequencies between 500 to 4000 Hz were employed for air and bone conduction ABR testing using a specified staircase threshold search to establish threshold levels and Wave V peak latencies. Median air conduction hearing thresholds using TB-ABR ranged from 0-20 dB nHL, depending on stimulus frequency. Median bone conduction thresholds were 10 dB nHL across all frequencies, and median air-bone gaps were 0 dB across all frequencies. There was no significant threshold difference between left and right ears and no significant relationship between thresholds and hearing loss risk factors, ethnicity or gender. Older age was related to decreased latency for air conduction. Compared to previous studies, mean air conduction thresholds were found at slightly lower (better) levels, while bone conduction levels were better at 2000 Hz and higher at 500 Hz. Latency values were longer at 500 Hz than previous studies using other instrumentation. Sleep state did not affect air or bone conduction thresholds. This study demonstrated slightly better Wave V thresholds for air conduction than previous infant studies. The differences found in the current study, while statistically significant, were within the test step size of 10 dB. This suggests that threshold responses obtained using the Kalman weighting software were within the range of other published studies using traditional signal averaging, given step-size limitations. Thresholds were not adversely affected by variable sleep states.
