PHY 104 Pitch, loudness, quality, timber Objective Question
Take CBT

Question

Why is a logarithmic scale, such as the decibel, considered appropriate for measuring loudness?
Options
A It simplifies complex calculations for sound engineers.
B The human ear's sensitivity to loudness is linear.
C The human ear is more sensitive to sound of very small amplitude than it is to sound of very large amplitude, requiring a nonlinear scale.
Correct Answer
D It allows for a wider range of frequencies to be represented.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The document explains: '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

Focus on the unique characteristics of human hearing mentioned in the text regarding amplitude sensitivity.
