What is the length of vocal folds in adult males?

The typical length of vocal folds in adult males is indeed in the range of 17-21 mm. This measurement is significant as it relates to the pitch and resonance of the voice. In general, longer vocal folds can produce lower frequencies, resulting in a deeper voice, which is characteristic of adult males.

Understanding this anatomical detail aids in grasping how variations in vocal fold length contribute to individual differences in voice, including gender distinctions. It also serves as a foundational aspect when discussing voice disorders or injuries; knowing the average dimensions can help in diagnosis and treatment. Thus, the length of vocal folds is a crucial factor in the fields of speech-language pathology and otolaryngology.
