This paper describes the distribution of energy and energy variance with frequency in the cries of normal and birth asphyxiated infants recorded within eight days of delivery. Single-variable statistical analysis suggested that asphyxiated infants have their cries shifted up in frequency compared to control infants, up to a frequency of 10 kHz.
本文描述了在出生后八天内记录的正常婴儿和出生窒息婴儿哭声中能量及能量方差随频率的分布情况。单变量统计分析表明，与对照婴儿相比，窒息婴儿的哭声频率上移，最高可达10千赫兹。
