后位聚焦口腔共鸣障碍对听障儿童嗓音的影响

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/(ae)/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.

The Effects of Posterior Focus on Deaf Children's Voice

Objective To investigate the effects of posterior focus on the voice quality of hearing-impaired children.Methods A total of 15 cases of 3~6 years old hearing-impaired children with posterior focus and 20 cases 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 (shimmer) and normalized noise energy (NNE) on each group of children of /(ae)/ were extracted and analyzed by Dr.Voice.Results Hearing-impaired children with posterior focus problems mainly showed the voice disorder of the hyperthyroidism type.The abnormal rate of shimmer values was the highest of hearing-impaired children with posterior focus, followed by F0, jitter and F0SD,and the minimum was NNE.The average value of the voice parameters was greater than hearing-impaired children without oral resonance disorders.The jitter and shimmer of children with posterior focus showed significant differences (P<0.05) compared to the hearing-impaired children without oral resonance disorders.Conclusion Children with posterior focus have a high rate of voice disorders and mainly change the voice jitter and shimmer.
