Ultrasound measurements of the vocal folds were taken for a number of boys passing through puberty. The boys were grouped according to their pubertal stage as defined by Tanner and there was a gradual increase in the length of the vocal folds as puberty progressed. The fundamental frequency of the boys' speaking voice was recorded via laryngography and a good correlation between the length of the vocal folds and the frequency of the voice was seen. The sudden drop in frequency seen between Tanner stages 3 and 4 did not correlate with similar changes in the length of the vocal folds at this time but stroboscopic findings suggest a change in the structure and mass of the vocal folds at this time of maximum frequency change.
对一些处于青春期的男孩进行了声带的超声测量。根据坦纳所定义的青春期阶段对男孩进行分组，随着青春期的进展，声带长度逐渐增加。通过喉描记术记录了男孩说话声音的基频，并且观察到声带长度与声音频率之间有良好的相关性。在坦纳3期和4期之间观察到的频率突然下降与此时声带长度的类似变化并无关联，但频闪观测结果表明，在频率变化最大的这个时期，声带的结构和质量发生了变化。
