As I understand dB, going from 1 to 2 db would only increase power output by approx. 25%. to double the loudness requires a 10dB increase and 10 times the power. Every three db requires twice the power. Using dB provide a standard with which to measure 'true' output, I suppose. Unlike a knob that is simple labeled from 1 to 10 or to 11 as in "Spinal Tap":)
