Fitting Exponential Models to Data · Exercise 161

The formula for measuring sound intensity in decibels $D$ is defined by the equation $D = 10 l o g (\frac{I}{I _{0}}),$ where $I$ is the intensity of the sound in watts per square meter and $I_{0} = 1 0^{- 12}$ is the lowest level of sound that the average person can hear. How many decibels are emitted from a rock concert with a sound intensity of $4.7 \cdot 1 0^{- 1}$ watts per square meter?
