#The bel is of rather recent vintage, 1923 [ A Dictionary of Scientific Units,

Nobody I knew of used neper.  Isn't it supposed to pertain to RF levels?
Nobody used bels either.  But everybody used decibels about sound levels.
And volume was something we measured in cubic meter.
Which leads to the next interesting question:  Why is sound level or
sound level control called 'volume?'
