目的 通过对学龄前儿童正常嗓音的声学分析为今后学龄前儿童的生理性和病理性嗓音的客观评价提供依据。 方法 应用计算机嗓音检测及分析系统对 130名 3～ 6岁的健康学龄前儿童的正常嗓音进行了检测和声学分析 ,并与正常成人进行了比较。 结果 学龄前儿童及其男女性之间 ,其嗓音的基频、频率微扰、振幅微扰及声门噪声等声学参数均无明显差异 ,但与成人之间则存在着明显的差异。 结论 年龄和性别对学龄前儿童正常嗓音的声学参数没有明显的影响 ,该年龄组儿童的正常嗓音的声学特征较为均衡
Objective To provide basis for the objective evaluation of the physiological and pathological voice of preschool children through the acoustic analysis of the normal voice of preschool children. Methods The normal voice of 130 healthy preschool children aged 3 ~ 6 years old was detected and analyzed by computer voice detection and analysis system and compared with normal adults. Results There were no significant differences in acoustic parameters such as fundamental frequency, frequency perturbation, amplitude perturbation and glottal noise among preschoolers and their male and female voices. However, there was a significant difference between adults and adults. Conclusion Age and gender have no significant effect on the acoustic parameters of normal voice in preschool children, and the normal voice of children in this age group is more balanced
