Question

The voice of women is shrill as compared to men because of the difference in their:

• A. speed
• B. loudness
• C. frequency
• D. all these

Answer 1

The correct option is C

frequency

Hint:

Knowledge of sound waves

The explanation for the correct option:

C) Frequency

• Because of the high frequency of sound, women are shill than men.
• The high-pitched sound and pitch of a sound are determined by its frequency. The higher the pitch, the higher the pitch of the voice.
• Women's voices are higher than men's because the sounds produced by women's vocal cords are higher than men's.
• Because their vocal cords are small. Because their vocal cords are longer than men's.
  

The explanation for the incorrect options:

A) Speed

• Sound wave velocity refers to the velocity at which a disturbance propagates from particle to particle.
• The speed of sound is defined as the distance traveled by a point of sound waves.
• Compression or decimation covered per unit time.
• The speed of sound remains the same at all frequencies of a particular medium under the same physical conditions.

B) Loudness

• Loudness is a phenomenon of sound that depends on the amplitude of sound waves.
• If the amplitude of the sound wave is large, the sound is said to be loud.
• Volume is directly proportional to the square of the vibration amplitude and is expressed in decibels $\left(dB\right)$.

C) All of these

• The speed of sound is defined as the distance traveled by a point of sound waves.
• Loudness is a phenomenon of sound that depends on the amplitude of sound waves.

Therefore, the voice of women is shrill as compared to men's because of the difference in their frequency (Option C)
