    10 log?

    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.
    The world is waiting. I must leave you now.

    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)
