Decibel Refresher Anyone

Well, WIA have provided this for everyone’s benefit:

On that link is a ~40 page PDF for your reading pleasure. I think it’s going to go into a far greater depth than my current knowledge of a bel being the logarithm of the ratio of two values and thereby the decibel being: dB = 10log(P1/P2)

(Okay, I know a smidge more than that, but only a smidge.)

Enjoy!
