Objective To explore the effective vocal training for a hearing-impaired child with vocal nodule. Methods The child with vocal nodule received the vocal training. A single-subject experimental design was applied to analyze the acoustic parameters such as FO, jitter, shimmer and NNE before and after the treatment so as to monitor the training effect. Results There was a significant difference in F0(P<0.05)and a very significant difference in NNE(P <0.01), but no significant difference in jitter and shimmer between baseline and treatment period(P>0.05). Conclusion The integrated vocal training including laryngea! Massage, vocal cord relaxation and yawn-sigh technique, is an effective approach for hearing-impaired children with vocal nodule.%目的 探讨听障儿童声带小结发声训练的有效方法.方法 对一名患有声带小结的听障患儿进行发声训练,采用单一被试法分析治疗前后声学参数F0、jitter、shimmer、NNE,监控其训练效果.结果 基线期与处理期的F0有显著性差异(P<0.05),NNE有极显著性差异(P<0.01),jitter、shimmer的改善无显著性差异(P>0.05).结论 喉部按摩、声带放松训练、哈欠-叹息法等综合发声训练对改善听障儿童声带小结有着较好的效果.
