[Acoustic elementary research on voice resonance of Chinese population].
OBJECTIVE
To explore the developing rule of formants of core vowels with age, and difference with gender.


METHODS
2492 normal people were randomly selected with 1318 males and 93 females,and divided to 4 groups according to age. /a/,/i/,/u/ of each child was recorded. Using D1200 to record normatively, reading data of formants in Real Analysis. Datawere analysis by SPSS13.0.


RESULTS
Formants of Core vowels had significant difference with age (P < 0.05), generally having a decreasing trend mainly with F1,F2 and deltaA (A1-A2) were different significantly as to gender; There were also significant difference between the formants of the core vowels (P < 0.05).


CONCLUSIONS
(1) There are significant effect of age,gender and core vowels(a,i,u)on F1, F2; (2) There are parallel correlation between developing trend of F1, F2 and that of F0.
