A construction explosion has an intensity / of 1.25 x 10^-4 W/m^2?. Find the loudness of the sound in decibels if L=10logI/I0 and I0= 10^-12 W/m^2
Round to the nearest tenth.
First, calculate the sound intensity in decibels using the formula L=10log(I/I0):
L = 10*log(1.25*10^-4 / 10^-12)
L = 10*log(1.25*10^8)
L = 10*8.0969
L = 80.969
Therefore, the loudness of the sound in decibels is approximately 81.0 dB.
