SI unit pascal and we measure pressure “levels” in dB. Decibels and nepers are used to measure power quantities as well as field quantities relative to a reference power P0, is defined to be 10 log10(P1/P0) dB .

To convert to dB, multiply Nepers by 8.686. To convert to dB, multiply Nepers by 8.686. The whole ball of wax boils down into the following totally cool closed-form equation: The level Lis the ratio we are using with sound recording techniques, that is in bel(after AlexanderGraham Bell) or in tenth part of it as decibel. Definition: dB is the twentyfold decadic logarithm ofthe ratio of two linear values x1and x0: Level L= 20 × log (x1/x0), where x0is the reference point. Question:The dynamic region of a standard audio CD is 96 dB.

To convert from decibel measure back to power ratio: P2/P1 = 10^(A/10) How to Convert Decibel to Neper. 1 dB = 0.1151277918 Np. 1 Np = 8.6860000037 dB. Example: Let x is the power ratio expressed in nepers and y is the power ratio expressed in dB. x = ½ ln (P1/P2) y = 20 log 10 (P1/P2) Dividing the two equations we get y/x = 20 log 10 (P1/P2)/ ln (P1/P2) = 20 log 10 e = 8.685 1 nepers is therefore equal to 20*log 10 e dB or 8.685 dB In high speed signal integrity, engineers often talk about the losses in the signal in terms of dB instead of watts. dB stands for decibels and Np stands for nepers. The formula used in decibels to nepers conversion is 1 Decibel = 0.115129254650564 Neper. In other words, 1 decibel is 9 times smaller than a neper.
