dB = 20 * log10 (amplitude) The amplitude in this case is expressed as a number between 0 and 1, where 1 represents the maximum amplitude in the sound file. For example, if you have a 16 bit sound file, the amplitude can go as …

Decibel: Db is a logarithmic ratio of a given level with a reference level. For example, if you would like to calculate RMS/Peak in dBFS, following code snippet may help you. public static void calculatePeakAndRms (short [] samples) { double sumOfSampleSq = 0.0; // sum of square of normalized samples. double peakSample = 0.0; // peak sample. for (short sample : samples) { …

L V = 20 × log 10 (V/V 0) (dB) (Z 1 = Z 2) where V is the voltage being measured, and V 0 is the reference to which V is being compared. The equation for obtaining voltage ratio V/V 0 from the level L V in dB is: V/V 0 = 10 (LV/20) The defining equation for the level in decibels for energy sizes (here power) is: L P = 10 × log 10 (P/P 0) (dB)

128 w = 107 dB. 256 w = 110 dB. As you can see, even relatively modest amplifiers can drive these speakers to healthy loudness levels in a normal room. The need for power escalates very quickly as you approach “lifelike” or “theater” levels of around 100-104 dB.

• dB value of 0.2 = dB value of (0.1 x 2) = dB value of 0.1 + dB value of 2 = -10 + 3 = -7 dB • dB value of 0.005 = dB value of (0.01 x 0.5) = dB value of 0.01 + dB value of 0.5 = -20 + (-3) = -23 dB. Special Decibel Abbreviations

The dB value is positive. (+) V 2 < V 1 or V out < V in means damping. The dB value is negative. (−) V 2 / V 1 or V out / V in means the ratio. The amplification or the damping in dB is: L = 20 × log (voltage ratio V 2 / V 1) in dB. V 1 = V in is the reference.
