Question

Which of the following voices is likely to have minimum frequency?
A. Baby girl
B. Baby boy
C. A man
D. A women

Answer 1

Hint in this type of the question we will check the appearance of sound to a human ear. Appearance of the sound to a human ear is categorized by the three parameters.
a. Pitch
b. loudness
c. quality.

Complete Step by step solution As we all know that the appearance of sound wave is categorized on the basis of
a. sound pitch
b. sound loudness
c. sound quality
We also know that pitch is directly proportional to the frequency of the sound.
The pitch of the adult man is minimal in comparison with the baby boy or baby girl and a woman.
As we have already discussed above that pitch and frequency are directly proportional.
And the pitch of adult men is minimal.
Hence we have concluded that if pitch of adult man will be minimum therefore frequency of man will also be minimum in comparison with baby boy or baby girl and a women

Hence option number c will be the correct option.

Note
About pitch and frequency:
Pitch of a sound is that sensation by which we differentiate a buffalo voice, a man voice and a female voice. We say that a buffalo voice is of low pitch, a man voice has higher pitch and a female voice has (generally) higher pitch than male. This sensation primarily depends on the dominant frequency present in the sound. Higher the frequency higher will be the pitch and vice versa. The dominant frequency of a buffalo voice is smaller than that of a male voice which in turn is smaller than that of the female voice
