Question

The standard measure used to compare sound intensities is the ______ .

Answer 1

Answer: Decibels

Explanation:

Decibel is the unit which used to measure intensity of sound. Sound intensity is the power carried by the sound waves per unit area perpendicular to it.

$I = \frac{P}{A}$ measured in W/m²

In decibels:

$I (dB) = 10 log_{10}\frac{I}{I_o}$

With each unit rise of decibel, the sound intensity varies by a factor of 10.
