Why do women’s voices typically have a higher pitch than men’s?
A
Because women generally have shorter and thinner vocal cords, which vibrate at higher frequencies.
B
Because women have larger larynxes, producing higher-pitched sounds.
C
Because women have more vocal folds, increasing the pitch of their voices.
D
Because women’s vocal cords are less flexible, resulting in higher pitch.
Verified step by step guidance1
Understand the concept of pitch: Pitch is determined by the frequency of sound waves, which is influenced by the vibration of vocal cords.
Recognize the anatomical differences in vocal cords: Women generally have shorter and thinner vocal cords compared to men, which allows them to vibrate at higher frequencies.
Relate the frequency of vibration to pitch: Higher frequency vibrations produce higher-pitched sounds, which explains why women’s voices typically have a higher pitch.
Eliminate incorrect options: Larger larynxes, more vocal folds, or less flexible vocal cords do not contribute to higher pitch. These options are anatomically or functionally inaccurate.
Conclude with the correct explanation: Women’s shorter and thinner vocal cords are the primary reason for their higher-pitched voices.
