目的：检查哥哥姐姐死于婴儿猝死综合症 (SIDS) 的婴儿的哭声声学特征，并将这些特征与非风险婴儿组进行比较。方法：从一组健康足月 (HT) 婴儿和 SIDS 婴儿的兄弟姐妹中收集疼痛诱发的哭声发作。从每个婴儿身上获得一次完整的哭声，并对其持续时间和频谱特征进行声学分析。结果：与 HT 组相比，SIDS 兄弟姐妹的哭声音调明显更高，反映了过度内收声带振动行为。哭闹的持续时间特征没有组间差异。结论：根据声学分析推断，HT 婴儿和 SIDS 婴儿的兄弟姐妹之间婴儿哭闹的喉部行为存在差异。因此，婴儿哭声的声音特征可以作为识别可能有 SIDS 风险的儿童的附加诊断标记。
Aim: To examine the acoustic features of crying demonstrated by infants whose older sibling died of sudden infant death syndrome (SIDS) and compare these features to a nonrisk group of infants.Methods: Pain‐induced crying episodes were collected from a group of healthy term (HT) infants and siblings of SIDS infants. One complete crying episode was obtained from each infant and analyzed acoustically with regard to durational and spectral features.Results: The cries of SIDS siblings were found to be significantly higher in pitch and reflected hyperadductory vocal fold vibratory behaviour compared to the HT group. There were no group differences with regard to durational features of crying.Conclusions: The laryngeal behaviour of infant crying, as inferred via acoustic analyses, differs between HT infants and siblings of SIDS infants. Accordingly, acoustic features of infant crying may serve as an additional diagnostic marker in the identification of children who may be at risk for SIDS.
