Chapter 4.5, Problem 12SP

(a)

To determine

To calculate: Intensity of sound for the leaf blower if $I_0={10}^{-12}{\text{W/m}}^{\text{2}}$ and $L=115\text{dB}$.

(b)

To determine

Whether the intensity of sound is above the threshold of pain if the intensity of the leaf blower as computed in part (a) as $I=0.3\text{W}/{\text{m}}^2$.
