临床研究 后位聚焦口腔共鸣障碍对听障儿童嗓音的影响 *郑惠萍1　肖永涛1　　【摘要】　目的　探讨后位聚焦口腔共鸣障碍对听障儿童嗓音的影响。 方法　选取 15 例 3～ 6 岁存在后位聚焦口腔共鸣障碍的听障儿童(共鸣障碍组), 20 例 3～ 6 岁无口腔共鸣障碍的听障儿童(对照组), 使用嗓音疾病评估仪分别对两组对象发/æ /音时的嗓音进行声学分析, 比较两组的基频(F0)、基频标准差(F0SD)、基频微扰(Jitter)、振幅微扰(Shimmer)和标准化噪声能量(NNE)。 结果　对照组 F0、F0SD、jitter 、shimmer、NNE值分别为 323. 52±45. 73 Hz、5. 35±3. 38 Hz、0. 27%±0. 16% 、2. 53%±0. 84%、- 16. 03±3. 16 dB;共鸣障碍组分别为328. 44±89.41 Hz、8. 59±7. 42 Hz、0. 74%±0. 79%、4. 48%±1. 44%、- 14. 92±7. 27 dB, 其中jitter 、shimmer 值显著大于对照组(P<0. 05);共鸣障碍组儿童主要表现为功能亢进型嗓音障碍, shimmer 值异常率最大(86. 67%, 13/15), 其次是F0(66. 67%, 10/15), jitter(53. 33%, 8/15)和 F0SD的异常率(53. 33%, 8/15), 异常率最小的是 NNE(20%, 3/15)。结论　后位聚焦口腔共鸣障碍听障儿童的嗓音异常率较高, 主要以 jitter、shimmer 值升高为主, 主要表现为功能亢进型嗓音障碍。【关键词】　后位聚焦口腔共鸣障碍;　听障儿童;　嗓音障碍DOI:10. 3969/j. issn. 1006- 7299. 2017. 03. 0网络出版时间:网络出版地址:【中图分类号】　R767. 92　　【文献标识码】　A　　【文章编号】　1006- 7299(2017)03- 0000 - 03The Effects of Posterior Focus on Deaf Children's VoiceZheng Huiping , Xiao Yongtao(Zhejiang Chinese Medical University, Hangzhou, 310053, China)　　【Abstract】　Objective　To invessigate the effects of posterior focus on the voice quality of hearing - impairedchildren. Methods　A total of 15 cases of 3～ 6 years old hearing- impaired children with posterior focus and 20 ca-ses of 3～ 6 years old without oral resonance disorders were included in this study. Fundamental frequency (F0),frequency standard deviation (F0SD), fundamental frequency perturbation (jitter), amplitude perturbation (shim-mer) and normalized noise energy (NNE) on each group of children of /æ/ were extracted and analyzed by Dr.Voice. Results　Hearing- impaired children with posterior focus problems mainly showed the voice disorder of thehyperthyroidism type. The abnormal rate of shimmer values was the highest of hearing - impaired children with pos-terior focus, followed by F0, jitter and F0SD, and the minimum was NNE. The average value of the voice parame-ters was greater than hearing- impaired children without oral resonance disorders. The Jitter and Shimmer of chil-dren with posterior focus showed significant differences (P <0. 05) compared to the hearing - impaired childrenwithout oral resonance disorders. Conclusion　Children with posterior focus have a high rate of voice disorders andmainly change the voice Jitter and Shimmer.【Key words】　Post focus;　Hearing- impaired children;　Voice disorder*　浙江省新苗人才计划项目(2015R410023)、188宝金博页面版部人文社科青年基金项目(16YJCZH121)联合资助1　浙江中医药大学听力与言语科学系(杭州　310053)作者简介:郑惠萍, 女, 浙江人, 听力师, 主要研究方向为听力与言语康复。通讯作者:肖永涛(Email:xiaoyongtao9@hotmail. com)　　发音器官包括动力器官 、振动器官、共鸣器官和构音器官,其中任何部分异常都可能产生发声功能障碍,影响嗓音质量[ 1]。儿童嗓音异常可妨碍其正常社会交流 , 影响生活质量 , 不利于儿童的健康成长 。由于听障儿童没有正常的听觉通路 , 无法监控自己的言语声,加之异常的呼吸和共鸣,往往容易产1听力学及言语疾病杂志 2017 年第 25 卷2017-05-03 11:15:49http://kns.cnki.net/kcms/detail/42.1391.R.20170503.1115.050.html
