One decibel (dB) is a logarithmic unit used to express the ratio between two values, commonly used in acoustics, electronics, and telecommunications. It represents a change in intensity or power level, with a difference of 10 dB corresponding to a tenfold increase in power. In terms of sound intensity, an increase of 1 dB is generally considered the smallest change in sound level that the average human ear can detect.
