The laryngeal prominence, commonly known as the Adam's Apple. During puberty, changes in the larynx typically result in a decrease in pitch in both males and females. On average, the male voice deepens by one octave while the female voice lowers by a few semitones. The fundamental frequency (pitch) of an adult female typically falls between 165 and 255 Hz and an adult male between 85 and 180 Hz. Anatomical changes during puberty include enlargement of the larynx for both sexes. However, the larynx descends and grows significantly larger in males which often results in a visible laryngeal prominence on the neck (Adam’s Apple). Additionally, male vocal folds become longer and thicker and resonant cavities become larger. These changes contribute to a deepening of the voice characteristic of pubescent males.<unk>  is characterized by the failure to transition into the lower pitched voice of adulthood. In conjunction with an atypically high pitch, common symptoms include a weak, breathy, or hoarse voice, as well as a low vocal intensity, pitch breaks, and shallow breathing.
