Abstract

This report provides information on the phonational frequency range and alternation of registration of male university students. Phonational frequency range is defined as that range of vocal frequencies encompassing both the chest and head voice registers.

The purpose of this study is, by understanding of voice essence and observation of changeable condition by acquired factors.

The results of comparative analysis between professional voice users(students of singing school) as study group and non-professional voice users as control group are as follows.

1) The phonational frequency range of study group is 22~38 semitones and that of control group is 20~34 semitones. There is 2~4 semitones difference between study and control group.

2) According to the average phonational frequency range of each grade, there is no significant difference in the study group but there is increasement of 1 semitones per each grade in phonational frequency range.

3) The persons who have longer voice training duration have more high phonational frequency range than who have shorter voice training duration.

4) Both control and study groups show that higher grades have higher phonational frequency range.

5) The alternation of the registrations are higher in the study group than in the control group, but in the study group the alternation of the registration is obscure.
