PHY 104 Pitch, loudness, quality, timber Objective Question

Question

Why is a logarithmic scale considered appropriate for measuring sound loudness?
Options
A It simplifies mathematical calculations for sound engineers.
B The human ear's sensitivity to sound intensity is non-linear.
Correct Answer
C It allows for the representation of sound frequencies more accurately.
D It inherently accounts for changes in sound pitch.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states 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.' This highlights the non-linear response of the human ear as the reason for adopting a logarithmic scale.

Hint

Consider how the human ear perceives differences in loudness across the spectrum of sound intensities.
