Description

Decibel Calculator. Translate ratios into decibel (dB) and back.There are two types of translations: 10*log(P/P0) and 20*log(U/U0).From Wikipedia, the free encyclopedia: "A decibel (dB) is one tenthof a bel (B), i.e. 1B = 10dB. The bel is the logarithm of the ratiobetween two power quantities of 10:1, and between two fieldquantities in the ratio. A field quantity is a quantity such asvoltage, current, sound pressure, electric field strength, velocityand charge density, the square of which in linear systems isproportional to power. A power quantity is a power or a quantitydirectly proportional to power, e.g. energy density, acousticintensity and luminous intensity. The calculation of the ratio indecibels varies depending on whether the quantity being measured isa power quantity or a field quantity. Two signals that differ byone decibel have a power ratio of 1.258925411794167 and anamplitude ratio of 1.122018454301963."
