Question Detail

PHY 104 Pitch, loudness, quality, timber Objective Question

Question

Why is a nonlinear, logarithmic scale appropriate for measuring loudness?
Options
A It simplifies complex calculations involving sound intensity.
B The human ear is more sensitive to sounds of very small amplitude than to sounds of very large amplitude.
Correct Answer
C It aligns with the inverse-square law of sound propagation.
D It allows for a wider range of frequencies to be represented.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states: 'It is worthy of note that 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 sound across different amplitudes.
