I reverted your edit to Decibel because it was incorrect. Please read the article carefully and think before you change things. A decibel is one-tenth of a bel, so 2 bels is 20 decibels; the number of decibels is ten times the number of bels, which is what the article said before your attempt to change it. - David Biddulph (talk) 15:53, 26 September 2013 (UTC)
