a doubling of POWER (or energy) is the same as the doubling of SOURCE (for instance....2 horns as opposed to 1, 4 horns as opposed to 2). doubling the source is NOT the same as double the amplitude (gain).

nowhere in my response did I state that perceived volume doubled, merely that perceived volume changes in relation to distance and angle to the source. 10db is a perceived doubling of volume. i do audio for a living.

its a 3db gain. yay for logs .
