They should first know that dB is a power measurement,
this is the fundamental fact on which the rest is based.
When they have grasped the basics, then they can be
shown that the voltage is a handy way of comparing two
power levels in the right circumstances (and they can
remember some handy voltage ratios if appropriate).
But most people working in audio don't need to compare
power levels, they need to compare voltage levels. I'd
teach them the "20" formula first. But then you may be
more into theory and less into practice than I am.
Agreed, since in my world, voltmeters vastly outnumber true watt meters.
QED.
