Question

A normal man is unable to hear the sound emitted by source. Out of the possible reasons, the one which is not applicable is
A. The pitch of the sound may be too high
B. The pitch of the sound may be too low
C. The quality of the sound is not matching with the man’s requirements
D. The amplitude of sound may be too small

Answer 1

Hint: The above problem can be resolved by the fundamentals of human ears and concepts on which the phenomena of hearing depend upon, along with the basic requirements that a human ear possess to perform desired functioning.

Complete answer: or Complete step by step answer:
Given:
A normal man is unable to hear the sound emitted by the source.
A normal human being can hear any particular sound only when the source emits the sound waves in the audible range for the human ears (20Hz to 20000 Hz). Beside this, there are some organs contributing in the human ears, that needs to fulfil with the basic requirements to sense the sound waves by a specific source.
Some examples include the fluid accumulating in the inner ear to cause the movement of hair cells. This movement can bring about the electrical signals from the sound waves to reach to the brain, supported by the auditory nerves.
Therefore, the appropriate reason behind the problem is that the quality of the sound is not matching with the man’s requirements.

So, the correct answer is “Option C”.

Note:
To resolve the given problem, one must remember the basic principles and fundamentals of hearing caused by the human ear. Moreover, the functioning of each and every part contributing to the human ear is also required to remember. Along with these, the fundamentals of sound waves are to be summarised as well as to be remembered.
