Infant irritability or colic is characterized by recurrent episodes of persistent, unexplained crying. The lack of a precise definition of the type and amount of cry that distinguishes an infant as colicky has hampered research and intervention efforts. The primary aims of this study are to describe the acoustic characteristics of cries of irritable infants and compare these to those of normal infants. Tape recorded cries of 11 irritable and 11 non-irritable infants were compared. The average age for infants of both groups was 8 weeks. The cries of irritable infants were higher in jitter, shimmer, proportion of noise, and tenseness than were the cries of control infants. Findings suggest that colic or infant irritability is more than just excessive crying. Acoustic characteristics of the cries of irritable infants reveal an increase in stress-arousal that supports the thesis of a state regulation disorder. Characterizing the nature and origin of the cries of irritable infants is essential to an understanding that will eventually guide appropriate diagnosis and management of these infants.
婴儿烦躁或腹绞痛的特征是反复出现持续且无法解释的哭闹。由于缺乏区分腹绞痛婴儿的哭闹类型和时长的精确界定，这阻碍了相关研究和干预工作。本研究的主要目的是描述烦躁婴儿哭声的声学特征，并将其与正常婴儿的进行比较。对11名烦躁婴儿和11名非烦躁婴儿的哭声录音进行了比较。两组婴儿的平均年龄均为8周。烦躁婴儿的哭声在抖动、闪烁、噪音比例和紧张程度方面高于对照组婴儿。研究结果表明，腹绞痛或婴儿烦躁不仅仅是过度哭闹。烦躁婴儿哭声的声学特征显示其应激唤醒增加，这支持了状态调节障碍的论点。明确烦躁婴儿哭声的性质和来源对于最终指导这些婴儿的恰当诊断和管理的理解至关重要。
