decibel [des´ĭ-bel]
a unit of relative power intensity equal to one tenth of a bel, used for electric or acoustic power measurements; one decibel equals approximately the smallest difference in acoustic power the human ear can detect and an increase of 10 decibels approximately doubles the loudness of a sound. Abbreviated dB or db.
Examples of decibel levels in everyday situations. From Frazier et al., 1996.
