Question

Which of the following voices is likely to have minimum frequency?
a) Baby Girl
b) Baby Boy
c) A man
d) A woman

Answer 1

Understand the concepts of Pitch and Frequency in relation to sound waves. Higher the frequency, higher the pitch and vice versa.

Complete answer:
In order to understand the frequency of sound waves produced by the above given options, it is essential that we understand the concept of pitch.
Pitch is defined as the property of sound, where a group of vibrations of particular frequency is grouped to produce sound tones. Now let us analyze the pitches of the given options
Generally, a baby’s tone and pitch will be comparatively high irrespective of its gender. So, the frequency produced will inevitably be higher as pitch is related to the frequency of the sound waves produced.
A man’s voice is generally deep toned and very low pitched when compared to the other mentioned in the example. Even while signing, male singers pitch is comparatively lesser than the pitch of female singers. Hence, the frequency produced by male voices is less.
A woman’s voice is generally soft toned and sweet as compared to man and the baby. Hence, the pitch of a woman’s voice is lesser than that of a baby, but arguably more than that of man’s voice. Thus, the frequency of a woman's voice is not the least out of the lot.

Hence, Option (c) is the right answer for the given question.

Note Sound frequency is defined as the number of times sound pressure waves repeat itself in a number of cycles with respect to time period. Sound waves travel from one maxima to minima or minima to maxima, depending upon the wave nature. Sound frequency is measured in Hertz.(Hz)
