In this study, the effect of age, sex, and disorder on the vocal performance of 230 children 6 to 11 years of age was investigated by means of the voice range profile (VRP). Ninety-four control children and 136 children with disorders were studied. The VRPs were quantitatively described by frequency and intensity characteristics, as well as by morphological characteristics. Significant differences between healthy children and children with disorders were found. Age has a different effect in girls than in boys regarding vocal performance. Most of the characteristics for the healthy girls change gradually over the period from 6 to 11 years. For the healthy boys, however, two age groups can be identified: one below and one above 8 years of age. It is hypothesized that the androgen dehydroepiandrosterone (DHEA) and its sulfate may play a role in this phenomenon.
在本研究中，通过嗓音音域图（VRP）对230名6至11岁儿童的年龄、性别和疾病对嗓音表现的影响进行了调查。研究了94名对照儿童和136名患病儿童。嗓音音域图通过频率和强度特征以及形态特征进行定量描述。发现健康儿童和患病儿童之间存在显著差异。在嗓音表现方面，年龄对女孩和男孩的影响不同。健康女孩的大多数特征在6至11岁期间逐渐变化。然而，对于健康男孩，可以识别出两个年龄组：8岁以下和8岁以上。据推测，雄激素脱氢表雄酮（DHEA）及其硫酸盐可能在这一现象中起作用。
