What Are Logarithmic Scales?

The loudness in decibels (dB) of a sound is defined as $10\log\frac{I}{I_0}$, where $I$ is the intensity of the sound in watts per square meter ($W/m^2$). $I_0$, the intensity of a barely audible sound, is equal to $10^{-12}$ $W/m^2$. City regulations require the loudness of construction work not to exceed $150$ dB. Suppose a construction team is is using a power drill. The drill has an intensity of $10$ $W/m^2$. Is the drill in violation of city regulations?
