Answer
$ \approx 105 dB$
Work Step by Step
Given the decibel equation $B = 10 \log \frac{I}{I_{0}}$
with $I_{0} = 10^{-12} \frac{W}{m^2}$
Given the intensity of the sound of a leaf blower at $I = 3.2 * 10^{-2} \frac{W}{m^2}$
Find the decibel level
$B = 10 \log \frac{3.2 * 10^{-2}}{10^{-12}}$
$B = 10 \log (3.2 * 10^{10})$
$B \approx 105 dB$
