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.

Answer: (A)

Verified step by step guidance

1. Understand the concept of pitch: Pitch is determined by the frequency of sound waves, which is influenced by the vibration of vocal cords.
2. 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.
3. 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.
4. 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.
5. Conclude with the correct explanation: Women’s shorter and thinner vocal cords are the primary reason for their higher-pitched voices.
