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

Question

Why is a logarithmic scale considered appropriate for measuring loudness, according to the document?
Options
A It simplifies calculations.
B The human ear is more sensitive to sounds of very small amplitude than very large amplitude.
Correct Answer
C It reflects the linear response of the ear.
D It allows for a wider range of frequencies to be measured.
Correct Answer

Option B 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 document's justification for using a nonlinear, logarithmic scale.
