Gregm, I think I'm getting confused! As I understand it, a doubling of power results in a (measured) 3db response in sound from a speaker, but the 3db, or even 6db, increase in volume isn't necessarily "percieved" by the listener as a "doubling" in volume. From what do you conclude the 6db increase in volume results in a "percieved" doubling of volume to the listener?
