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.
