The difference in vocal cord length between men and women is the reason why women’s voices are usually higher and more vocal.
Voice is produced with the help of vocal cords.
Female voices are usually higher and clear. This happens because of the frequency . Frequency is the number of vibrations per second, the higher the frequency, the louder the voice or sound.
In humans, voice is produced with the help of the vocal cords (the vocal cords of the larynx). However, the vocal cord lengths of women and men are different.
The female vocal cords are about 15mm long, while the male vocal cords are about 20mm long. Since male vocal cords are relatively longer, they vibrate less per second. Thus, producing a lower frequency sound. In contrast, the shorter female vocal cords vibrate more per second, producing high-frequency sounds. Because of the higher frequency of sound, women usually have a higher and clear voice than men.
