But if two people talking is power because their talking is uncorrelated (even

as before) would be an amplitude thing as it is correlated. No?

May I ask why you used 10*log(2/1) in your two
person example?
You mean why power and not amplitude ? Two persons talking would
produce twice the power, since the signals are not correlated.
So if our idea of 'twice as loud' would be determined by such
experiences (but it clearly isn't), it would refer to power.
