If one assumes that the loudness of a sound is proportional to its power
and that the power is proportional to the square of the amplitude, then
Dodge's method is correct. Most commercial mixing boards follow Dodge for
the pan pots.

The situation is of course not that simple but Dodge is usually a good
starting point.
