Auditory-evoked brain stem responses (BSRs) were recorded from the scalp in 4 cats and 10 human subjects. Auditory stimuli consisted of 1 kHz tone bursts and their duration, intensity and rise--decay time were varied. The BSR evoked by the tone bursts consisted of on- and off-responses. The off-responses showed different intensity--amplitude and different intensity--latency functions from the on-responses. In the feline subjects, an increase in rise time as an input resulted in an increase in the number of recorded sharp waves of the on-responses, indicating that several cycles of tone bursts during the rise time take part in generating on-responses. In both the feline and human subjects, BSRs were evoked by tone bursts with a rise time of as long as 10 msec; an increase in the rise time resulted in an increased latency and broadened waveforms of the on-responses. These demonstrated properties of BSR may provide useful information in determining input parameters, such as rise--decay time, appropriate for audiometric assessment.
在4只猫和10名人类受试者身上，从头皮记录听觉诱发脑干反应（BSR）。听觉刺激由1kHz的短音脉冲组成，其持续时间、强度和上升-下降时间各不相同。短音脉冲诱发的BSR包括起始反应和终止反应。终止反应与起始反应相比，表现出不同的强度-振幅和强度-潜伏期函数。在猫科动物受试者中，作为输入的上升时间增加导致记录到的起始反应锐波数量增加，这表明上升时间内的几个短音脉冲周期参与了起始反应的产生。在猫科动物和人类受试者中，上升时间长达10毫秒的短音脉冲均可诱发BSR；上升时间增加导致起始反应的潜伏期延长和波形变宽。这些已证实的BSR特性可能为确定适合听力测定评估的输入参数（如上升-下降时间）提供有用信息。
