At what distance would the noise from a jackhammer (at 30m it
has a sound intensity level of 105 dB) be comparable to the noise
from everyday life (80 dB)? Assume that there is no sound
absorption due to air and that the jackhammer is an isotropic
source of sound. We will solve this in steps.
*Note that, for answers that are in scientific notation, My Open
Math accepts a capital E for the "EE" shortcut. Here's an example:
1.22E-5 for 0.0000122
a) What is the intensity of the jackhammer at 30
m? Wm2Wm2
b) What is the intensity of the jackhammer at 80
dB? Wm2Wm2
c) What is the jackhammer's power? W
d) What distance from the jackhammer is needed to drop the sound
level to 80 dB? m
