Answer:
Explanation:
log10 function is required to convert dB into intensity of a sound. Both are measures of loudness of a sound and the relationship can be expressed as follows:
dB = 10 log10(I/Io), where Io is 10^-12 W/m^2
Substituting, 82 = 10 log10(I/10^-12)
I = 0.0001585 W/m^2
or 1.58*10^-4 W/m^2
