[Singing formant analysis of KunQu actors in their mutation and grown-up].
OBJECTIVE
To compare the singing formant differences between successful opera actors and non-successful opera actors during their adolescence period, and to compare the same index between adolescence and adult period of successful actors.


METHODS
From 1985 to 1986, the author had 21 adolescent actors' voice recorded, all of them were from Beijing KunQu opera troupe. In 2000, all the 21 subjects had their voice recorded and singing formant (Fs) analyzed by using computer and sound spectrograph, 7 of them had become adult actors, others quitted their actors career after adolescents period.


RESULTS
Successful actors have obvious Fs, and stronger acoustic energy; successful actors had weaker Fs value during adolescence period than during adult period (t = 2. 9600, P < 0.05).


CONCLUSIONS
Fs's presence and its acoustic energy were important to evaluate adolescent actors future locality potential.
