The decibel (symbol: dB) is a relative unit of measurement corresponding to one tenth of a bel (B) It is used to express the ratio of one value of a power or root-power quantity to another, on a logarithmic scale A logarithmic quantity in decibels is called a level Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately 125893) or (sometimes equivalently) an amplitude (field quantity) ratio of 101⁄20 (approximately 112202)The unit is used to express a change in value (eg, +1 dB or −1 dB) or an absolute value
