Eighteen full-size, full-term, healthy, newborn infants were used in an experiment to determine the relative efficiency of three different noise spectra as audible stimuli. These three signals were high-pass filtered noises with cutoff frequencies of 500, 1000, and 2000 Hz. The metric of efficiency was a very simple count: how many times did an infant display an arousal response to each signal? Each of the three signals was presented eight times to each infant, but the 24 signals were presented in a different random order to each infant. Results showed that neonates are more responsive to wider band signals but are also responsive to lower frequencies. These data are consistent with our earlier findings (also described) and continue to support the use of calibrated wideband signals for auditory screening of newborns.
18名足月、健康的足月儿被用于一项实验，以确定三种不同噪声频谱作为可听刺激的相对效率。这三种信号是截止频率分别为500、1000和2000赫兹的高通滤波噪声。效率的衡量标准非常简单：婴儿对每个信号表现出觉醒反应的次数。这三种信号中的每一种都向每个婴儿呈现8次，但这24个信号以不同的随机顺序呈现给每个婴儿。结果表明，新生儿对宽带信号反应更灵敏，但对低频也有反应。这些数据与我们早期的研究结果（也有描述）一致，并继续支持使用校准后的宽带信号对新生儿进行听力筛查。
