Bel is a measure of comparative power, or loudness, i.e., a unit of relative power ratio. The number of decibels is the decimal logarithm of the relative power ratio, which is expressed mathematically as follows: dB = 10 log 10 (P 1 /P 2 ) where dB = deciBel, P 1 is the power level to be measured, and Se hela listan på fr.wikipedia.org Decibels synonyms, Decibels pronunciation, Decibels translation, English dictionary definition of Decibels. decibel range of human hearing in decibels n.
