Wrong. (Do I have to use that much punctation in kind?)
3db expresses 1/2 or 2/1 in electrical energy, ie wattage. So there is
a difference of 3db between a signal driven by a 100 watt amplifier and
a 200 watt amplifier of the same class, in simple terms. Auditioned
through the same speaker system the volume difference is perceptible
but experts seem to think that its toward the small end divisio: in
comparative broadband situations 1.5 db (or even 2db seems to be about
what the average listener can actually discern.
10db on the other hand is the difference between a 100 watt amp and a
1000 watt amp, and THAT is what is considered twice as loud. Real-world
experience in studio and on the bandstand has borne that out as well.
