Abstract [en]

It has been well documented in adult studies that, as overall vocal intensity increases, the resulting increase in partials is greater in higher than in lower frequencies. Investigations involving children’s normal productions are uncommon however, and there is, as a consequence, little knowledge of how children’s vocal function differs from that of adults. Using long term average spectrum (LTAS) analysis, this study investigates the effects of vocal intensity variation on the voices of fifteen schoolchildren aged 10 years, singing in soft, mid and loud voice. Mean amplitudes, dynamic range, and gain in each frequency band were calculated, and means are presented as normative data for children’s vocal productions. Observed systematic effects of vocal loudness as well as male-female differences in the averaged spectra are discussed, and comparisons with adult data made.
