Homework Help: Math

Posted by Marcy on Wednesday, December 10, 2008 at 12:39pm.

How would I solve this Equation?

DB = 10log(I/Io)
DB = 10log (140 Io/Io)
DB = 10 log (140)
DB = ?????

This is as far I have gotten on this equation. Can someone please help me finish? I am trying to determine how many times louder than the threshold of sound is from 140 Decibels.
