Question
When the intensity of sound increases from 10⁻¹ W/m² to 1 W/m², what is the increase in loudness in decibels (dB), as calculated in the document?
Correct Answer
Option A is the correct answer.
Detailed Explanation
The document explicitly calculates the increase in loudness as 'L(10⁻¹ →1W / m) = 10log₁₀(1 / 10⁻¹) = 10log₁₀10 = 10 dB'.
Hint
Look for the specific calculation showing the 'increase' from 10⁻¹ W/m² to 1 W/m².
