摘要： 目的探讨3~6 岁听力障碍儿童的嗓音声学特点。方法采自148 名3~6 岁听障儿童和122 名3~6 岁健听儿童的声样，检测声样的声学参数值：基频(F0)、基频标准差(F0SD)、基频微扰(jitter)、振幅微扰(shimmer)、声门噪声能量(NNE)、开商(OQ)、速度商(SQ)、幅度商(AQ)、声门频谱斜率(STF)。结果听障儿童F0、SQ、STF、F0SD、jitter 高于健听儿童(P<0.05)，shimmer、NNE、OQ、AQ与健听儿童无显著性差异(P>0.05)。除3~4 岁健听儿童的NNE 显著低于5~6 岁儿童外(P<0.05)，其余各项声学参数值在不同年龄儿童之间均无显著性差异(P>0.05)；各项声学参数值在男童和女童间均无显著性差异(P>0.05)。结论听障儿童发声时声带振动速度快、闭合快且激烈，声带振动的稳定性和规律性较差。声学参数F0、F0SD、jitter、shimmer、NNE、OQ、SQ、AQ、STF 不受性别影响；除NNE 外，也不受年龄影响。

Abstract: Objective To investigate the acoustic characteristics of the voice of 3~6 years old children with hearing-impairment. Methods The voice samples were collected from 148 hearing-impaired children and 122 normal children, all aged 3~6 years. The acoustic parameters including F0, F0SD, jitter, shimmer, NNE, OQ, SQ, AQ, STF were compared. Results The F0, SQ, STF, F0SD, jitter were more in the children with hearing-impairment than in the normal children (P<0.05). There was no significant difference between hearing-impairment and normal children in shimmer, NNE, OQ and AQ (P>0.05). There was no significant difference of all the acoustic parameters among children with different ages (P>0.05), except the NNE was less in 3~4 years old children than 5~6 years old children (P<0.05). There was no significant difference of all the acoustic parameters between boys and girls (P>0.05). Conclusion The vibration of vocal cords is instable and irregular,saying overquick and close intensely in hearing-impaired children. The age and sex do not influence the acoustic parameters, except NNE is less in younger children.
