The Auditory Response Cradle enables physiological response measures to be recorded from the neonate. Auditory responses are detected in the form of head rotation, startle, body activity and respiration changes. This paper reports the results of trials with 203 neonates using 250 and 1000 Hz pure tone and broad band noise stimuli. Response criteria are determined and spontaneous control 'responses' compared with those resulting from stimulus presentation. The response rate is correlated with the measured intra-meatal sound pressure level. Clear response thresholds are determined for all three stimuli. The sharpness of these motor thresholds is discussed and found to have significant implications for cost-effective neonatal auditory screening.
听觉反应摇篮能够记录新生儿的生理反应指标。听觉反应通过头部转动、惊跳、身体活动和呼吸变化等形式被检测到。本文报告了对203名新生儿使用250赫兹和1000赫兹纯音以及宽带噪声刺激进行试验的结果。确定了反应标准，并将自发对照“反应”与刺激呈现所产生的反应进行了比较。反应率与测得的耳道内声压水平相关。确定了所有三种刺激的明确反应阈值。讨论了这些运动阈值的敏锐度，并发现其对具有成本效益的新生儿听力筛查具有重要意义。
