Find the number of decibels for the power of the sound. Round to the nearest decibel.

Question

A rock concert, 5.3 10-6 watts/cm2

Answer 1

db = 10*Log(5.3*10^-6)
db = 10*(Log5.3+LOg10^-6)db = 10*(
db = 10*(0.724-6) = -53.

Answer 2

Correction:
db = 10*Log(5.3*10^-6)
db = 10*(Log5.3-Log10^-6)
db = 10*(0.724-6) = -53.
