Question
What is the unit used to express the logarithmic ratio between two levels of sound intensity, typically with a reference intensity I₀?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 19 states: 'The decibel (dB), one-tenth of a Bel, is more often used as the unit of measurement.' and 'L = 10log₁₀(I/I₀) is the loudness in decibels'.
Hint
This unit is commonly used for measuring sound levels due to the non-linear perception of loudness by human ears.
