You can put this solution on YOUR website! Find the number of decibels for the power of the sound. Round to the nearest decibel.
A rock concert, 5.15 10-6 watts/cm2
D= db
-----
db = 10log(I/Io)
Io = 10^-12
---
db = 10log[(5.15x10^-6)/(10^-12)]
db = 10log[5.15x10^6]
db = 10[log(5.15 + log(10^6]
db = 10[6+0.712]
db = 67.12
