| 摘 要： | 目的探讨两种噪声环境下嗓音的声谱图特点。方法选择健康青年25人，进行一定训练后，分别在安静环境、白噪声环境、语音环境下进行录音；录音内容包括持续元音／a／i/；用Doctor Speech软件分析，对基频、共振峰进行比较。结果男性／a／音、女性／a／音、女性／i／音基频在噪声环境下明显提高；男性／a／音、男性，i／音、女性／i／音，第一共振峰(F1)在噪声环境下明显提高。结论噪声环境可影响正常人嗓音的基频、共振峰。

| Abstract: | Objective To find out the changes of voice in different noisy background by computer acoustic analysis.Methods 25 young people with normal hearing and normal vocal cords were selected.Sustained /a/ and /i/ were recorded in three different background:quiet, white band noise and speech noise. The software of Multi Speech and Doctor Speech were used. Testing parameters included: Fo, mean amplitudes, standard deviations of amplitudes,F 1, F 2.Results Fundamental frequencies of noisy groups were significantly higher in male-/a/, female-/a/ and female-/i/.F 1 of noisy groups were significantly higher in male-/a/, male-/i/ and female-/i/.Conclusion Fo and F 1 of normal people can be changed by noise of backgroud. |
