On the decibel scale, the loUdness of a sound, D, in decibels, is given by $D=10\mathrm{log}\frac{I}{{I}_{0}}$ where I is the intensity of the sound, in watts per $mete{r}^{2}$, and ${I}_{0}$ is the intensity of a sound barely audible to the human ear. If the intensity of a sound is ${10}^{12}{I}_{0}$ what is its loudness in decibels? (Such a sound is potentially damaging to the ear).
