Altogether 248 cries from 62 infants with hydrocephalus were analysed by sound spectrography: 92 cries from infants with congenital hydrocephalus and 52 cries from each of the groups with cerebral malformations, hydrocephalus as sequelae of meningitis, and after closure of a meningomyelocele. The cries were compared with 104 cries of normal healthy infants of corresponding age. The cry analysis showed that the most abnormal cries were seen in infants with congenital hydrocephalus and cerebral malformations. The pitch of the fundamental frequency did not differ from normal crying in cries of infants collected after recovery from meningitis and after closure of a meningomyelocele. The cries in hydrocephalus after meningitis showed more commonly flat melody types and the occurrence of bi-phonation.
通过声谱分析对62例脑积水婴儿的248声啼哭进行了分析：其中92声啼哭来自先天性脑积水婴儿，另外52声啼哭分别来自患有脑畸形、脑膜炎后遗症脑积水以及脊髓脊膜膨出修补术后的婴儿组。将这些啼哭与104例同龄正常健康婴儿的啼哭进行了比较。啼哭分析表明，先天性脑积水和脑畸形婴儿的啼哭异常最为明显。脑膜炎康复后及脊髓脊膜膨出修补术后采集的婴儿啼哭，其基频音高与正常啼哭无差异。脑膜炎后脑积水婴儿的啼哭更常见为平调旋律类型且双声现象发生率较高。
