_{1}/P

_{2}

I just don't get what the P1 and P2 are exactly but I know that dB is a ratio that expresses 2 values?

And also, how do you compare two values of dB. Say, there's 80dB and 105dB, how do you work out how many times louder is the 105dB compared to the 80dB?

Any help will be greatly appreciated, thank you.
