[Study on the nasal resonance]
1Department of Otolaryngology, People's Hospital, Beijing Medical University, Beijin 100044.
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 frequency and the number of harmonics of five vowels [a], [e], [i], [o], [u] were compared before and after packing of the anterior 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.
