It isn't tho. It's close but not exactly. And there's nothing about -3 behing half that makes sense except for familiarity (and it's not even wide-spread familiarity - most people wouldn't know how much louder +3dB is).
It's just an unnecesarilly confusing definition that stuck for historic reasons.
- danadam 1y ago> It isn't tho. It's close but not exactly. It isn't tho :-). It's not close to double loudness. It's double power, which is 1.41 higher sound pressure, which is only slightly louder.
