This online converter allows you to easily convert between bel (b) and decibel (db), providing instant results with high precision.
Bel (B)
Definition: The bel (symbol: B) is the original logarithmic unit (1 B = 10 dB) expressing power ratios on a base-10 logarithmic scale.
History: Created by Bell Labs for telephone transmission measurements. Named after Alexander Graham Bell. The decibel (0.1 bel) proved more practical for most applications.
Current use: Rarely used directly today, having been largely replaced by decibels. Appears in some historical contexts and theoretical discussions.
Decibel (dB)
Definition: The decibel (symbol: dB) is a logarithmic unit used to measure sound intensity level relative to a reference value. It expresses the ratio between two sound pressures as ten times the base-10 logarithm of the ratio.
History: Developed in the 1920s by Bell Labs to measure signal loss in telephone circuits. Named after Alexander Graham Bell. Originally based on the bel (1 dB = 0.1 B), but decibels became more practical for most audio measurements.
Current use: Standard unit for sound pressure levels (SPL), audio equipment specs, and noise measurements. Used from quiet libraries (30 dB) to rock concerts (110+ dB) and hearing safety regulations.
