Question
Why is a logarithmic scale, such as the decibel, considered appropriate for measuring sound loudness?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The text explains: 'the ear is more sensitive to sound of very small amplitude than it is to sound of very large amplitude. Thus, a nonlinear scale is appropriate. This is provided by the logarithmic measure.'
Hint
Consider how the human ear perceives changes in loudness across different intensity levels.
