Voice profiles and standard voice profile of untrained children
1Hals-Nasen-Ohren Klinik, Klinikum rechts der Isar, Munich, Germany.
Abstract:
Voice profiles were taken of 277 healthy children between the ages of 5 and 14 years. The measured phonetograms were grouped according to sex and years of age. In each group, the means and standard deviations of maximal and minimal volume of each frequency were calculated. The median was used to establish the upper and lower limits of the voice range of each group. No age-dependent changes of the group voice profiles were shown in the groups of 7 to 10 year olds. Out of that emerged a standard childhood voice profile of the untrained voice. After age 10, an increase of the dynamic range over the lowest frequencies was found. Because of the voice changes in puberty, a profile for 13- and 14-year-old boys could not be established.
