dB
dB is the acronym for Decibal.
Decibal
A unit used to express the ratio of two values of a power or root-power quantity, typically used in acoustics, electronics, and control theory. It is one-tenth of a Bel (B) and measures sound intensity relative to a reference level.
In sound measurements, decibels can describe the power ratio between different audio sources or the intensity of a sound compared to a threshold of hearing, with 0 dB representing the faintest sound the average human ear can perceive.
The decibel scale is logarithmic, meaning each 10 dB increase represents a tenfold increase in intensity, making it more aligned with human perception of loudness than a linear scale.
