|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
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.
How to calculate decibels?
