Yeah should have included the link maybe. Possibly also lots of people don't know any better since 90% or more of the time the media reports about audio levels it's always plain 'decibel'. Even though that makes no sense whatsoever. It's like saying 'and now drive 1' without specifying a unit. Yet, I would have expected more from the average HN user with anough karma to downvote.
