Why? dB is logarithmic so it's difficult for people to picture how loud something is, if that's the only number given.

And so are our ears. That's why we use db. So 12db is not perceived by us to be 94% quieter.

So its 94% less sound because this seems sound calculated -12db in % with conventional formulas?

How would we describe perceived sound exactly, not many people can imagine something when given a db value? Maybe we should?

When loudness is described there's often lists with examples of things with their typical loudness specified in dB, so you can compare against things you may have heard.
