The Loudness $\beta$ Of Sound, in Decibels (DB), Is Dependent Upon the Sound

Essay

The loudness $\beta$ of sound, in decibels (dB), is dependent upon the sound intensity I according
to the following equation: $\beta = 10 \log \left( \frac { I } { I _ { 0 } } \right) \text { where } I _ { 0 }$ is the original intensity and I is the new
intensity.By how many decibels does the loudness increase when the intensity doubles?
