+The **decibel** (dB) is a logarithmic unit used to express the ratio of two values, often representing [Power](/wiki/power) or [Intensity](/wiki/intensity). It simplifies the comparison of vast ranges in quantities like [Sound](/wiki/sound) levels or signal strengths, making complex measurements more manageable.
