Name the unit in which intensity of sound (loudness) is measured.

Answer 1

Step 1:

Units of intensity

The loudness of the sound is measured in the unit called as decibel (dB).

It is expressed as

$I\left(dB\right)=10{\log }_{10}\left[\frac{I}{I_0}\right]$ where $I$ and $I_0$ are the intensities of the sound.
