Bel

 

the unit for a relative logarithmic quantity (the logarithm of the ratio between two physical quantities of the same name) that is used in electrical engineering, radio engineering, acoustics, and other branches of physics. It is designated by the letter B and is named after the American inventor of the telephone, A. G. Bell. The number of bels N, which corresponds to the ratio of two energy quantities P1 and P2 (which relate to power, energy, energy density, and so on), is expressed by the formula N = log (P1/P2); for “force” magnitudes F1 and F2 (voltage, current strength, pressure, field strength, and others), it is expressed as N = 2 log (F1/F2). The tenth part of a bel, called a decibel (dB), is usually used.
