COMMENTS

This is the ratio of +1 dB (one decibel). 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
