Axiom Home Page Forums General Discussion Advice from Axiom Owners Why is it not 1,2,3

I this my sound dumb but when I was in the O.R one day and when I went to turn on the music the volume was -dB. I understand what it means but for other people they don't.

Why did they change the volume, most times its from 1,2,3,ect. Why did it get changed? Also on most low end audio (CD Player) it is still 1,2,3, ect, but it you spend 200$+ the volume is in dB. Just b/c I spend 200$+ on a CD plays does not mean I understand. Thanks for taking the time to read my dumb question, well more like a stupid rant.
