We're given a lawnmower with a sound intensity of 0.005
W/m2 at a distance of 3 m. The sound power of
the lawnmower works out to be 0.1414 W:
I = P/(4∏r2) --> P = I * (4∏r2)
P = (0.005 W/m2) * (4∏(1.5 m)2)
P = 0.1414 W
Now, you move 20 m away from the lawnmower. What is the
intensity level (in dB) from the lawnmower, at this position?
