This study evaluated the effects of stimulus repetition rate, phase, and frequency on the auditory brainstem response (ABR) in normal-hearing neonates and adults. In both neonates and adults, the results clearly showed large ABR wave V latency differences between condensation and rarefaction for low-frequency stimuli. Phase dependent latency effects are believed to be a result of the phase-sensitive low-frequency neurons. Increasing stimulus repetition rate produced greater wave V latency shift in neonates than in adults. The consequences of rate changes were independent of stimulus phase and frequency.
本研究评估了刺激重复率、相位和频率对听力正常的新生儿和成人听觉脑干反应（ABR）的影响。在新生儿和成人中，结果均清楚显示，对于低频刺激，密波和疏波之间的ABR波V潜伏期存在显著差异。相位依赖性潜伏期效应被认为是相位敏感的低频神经元的结果。与成人相比，增加刺激重复率在新生儿中产生的波V潜伏期偏移更大。重复率变化的结果与刺激相位和频率无关。
