鼻腔共鸣作用的初步研究

Study on the nasal resonance

：进一步明确作为人体的共鸣器官之一的鼻腔和鼻窦共鸣作用。方法：对前鼻填塞前后５个元音［ａ］、［ｅ］、［ｉ］、［ｏ］、［ｕ］的谐音的最大频率、谐音的平均频率、谐音的数目进行了比较。结果：经统计学分析堵塞前后均无显著性差异。结论：证实了鼻腔的前部对鼻腔的共鸣作用影响不大。

objective: In order to understand the resonant function of the nasal cavity (including nasal sinuses) which is one of the resonant organs of the human body. Method: The maximum frequency, mean frequencyand the number of harmonics of five vowels[a]. [e] . [i] . [o].[u] were compared before and after packing of theanterior nasal cavity. Result: The result was analyzed statistically and showed no significant difference. Conclusion:It proved that the front part of the nasal cavity plays no important role in the function of the nasal resonance.
