Decibels are the principal way how power ratios are measured in electric and electronic engineering, acoustics, meteorology, optics and other engineering branches. Corresponding amplitude (rather than power) ratio is given by the square root of this constant (A011289). - _Stanislav Sykora_, Apr 02 2012 %D A011279 Donald Fenna, A Dictionary of Weights, Measures, and Units.
