title: [Examination of the vocal range in school children].
abstract: The author examined in 50 children (pupils of the 1st 50 5th form of primary school), selected at random, the vocal field. The group comprised 22 boys and 28 girls, always 10 children from the same form. Their mean vocal range was 17 semi-tones from G sharp to C2. The maximal dynamic range varied between 10 and 13 dB and did not exceed the intensity of 75 dB A. These results suggest relatively limited dynamics of the singing voice in children and indicate the optimal vocal position and range. Marked transcendence of these limits is probably one of the reasons which lead in some children singing in choirs to overburdening of the vocal organ and may lead to the development of hyperkinetic dysphonia.
