1. The problem statement, all variables and given/known data Calculate the sound level in decibels of a sound wave that has an intensity of 4.00u "W/m2. 2. Relevant equations dB = 10log(I/Io) 3. The attempt at a solution dB = 10log(4/1E-12) = 126.02 db Book says 66db. It vaguely covers this topic, not sure if I had missed something or not.
