The problem with db is that double the amount of db doesn't mean it's twice as loud. That's why it's kinda hard to compare. With Sone it's easier. Something with 2 Sone is twice as loud as something with 1 Sone.
In reality, it's a little more complicated of course (talk about perceived noise and stuff), but that's what it all comes down to and why db gets used less and less.
edit: Oh damn, too slow. :P
