Bel

A unit of measure, named for Alexander Graham Bell, commonly used in expressions of sound intensity (dB) and Radio Frequency signal strength (dBm). One Bel is equal to ten decibels. The Bel was first commonly used in the early telecommunications industry as a unit to denote the amount a signal dropped in level over a one-mile distance of telephone wire.
