View Full Version : 10 log?

05-19-2003, 03:38 AM
I need someone to explain to me what the math formula 10 log equates to in common SPL formulas. I can't get my head straight on it and most websites seem to lose me halfway through.

Decently simple would be nice.

An example calculation:

10 log 540 = ?

What's the magic behind 10 log! That's what I want to find out, so I may insert my own numbers and manipulate at will.

Thanks for any input.

10^a = b


a = 10log b

10^10log a = a

10log 10^a = a

(Not a good explanation perhaps, but a simple example on how log is connected to powers. They are kind of their others inverse)
