Problem: A certain sound has an intensity of 2.0647×103 W/m2.
Part A- What is the sound intensity level in decibels (dB)?
Please explain your answer for above problem. I know substitution is involved so be sure to give a detailed explanation on that as well. Express your result to three significant digits.
