The level L is the ratio we are using with sound recording techniques, that is in bel (after Alexander Graham Bell) or in tenth part of it as decibel. Definition: dB is the twentyfold decadic logarithm of the ratio of two linear values x1 and x0: Level L = 20 × log (x1 / x0), where x0 is the reference point.
Question: The dynamic region of a standard audio CD is 96 dB. How many bels are this?
 Help: 1 dm = 0.1 m and 1 dB = 0.1 bel 
1 m = 10 dm and 1 bel = 10 dB
A given power level P, measured with respect to the reference power level Pref,
would be equal to Formula. So, 1 bel = 10 dB.

Conversion from neper to decibel and vice versa

Note: There is no conversion formula for measured       
           dB values to weighted dBA values or vice versa.
