WebApr 20, 2005 · A decibel (dB) is a unit used to express relative differences in signal strength. A decibel is expressed as the base 10 logarithm of the ratio of the power of two signals, as shown here: dB = 10 x Log 10 (P1/P2) … WebThe actual equation used to calculate dB is: dB = 10 log (measured power/reference power). So 10 dB is a ratio of 10 (either 10 times as much or 1/10 as much), 20 dB is a ratio of 100, 30 dB is a ratio of 1,000, etc. When the two powers are equal, dB = zero—a result of the log scale used, but a convenient value that’s easily remembered.
