Decibel 〈iOS〉

The is a logarithmic unit used to express the ratio between two values, most commonly sound intensity or electrical power. Unlike linear scales (like inches or pounds), the decibel scale compresses vast ranges of numbers into manageable figures, reflecting how human senses—specifically hearing—actually perceive change. Core Concepts

, the threshold of human hearing. In digital audio, (Full Scale) measures signal level relative to the maximum a system can handle before clipping. Examples of Common Decibel Levels Decibel

: The scale is not linear. An increase of 10 dB represents a 10-fold increase in sound intensity and roughly a doubling of perceived loudness. The is a logarithmic unit used to express

Because the scale is logarithmic, you cannot simply add decibel numbers together. Decibel
