In audio technique the following 'power or energy amplification ' is rather unusual. The calculator works in both directions of the ↔ sign. If you search for the amplification ratio, given the dB value,Īmplification (Gain) and Damping (Loss) To use the calculator, simply enter a value. Using power we get: Level in dB: L = 10 × log (power ratio) 3 dB = twice the power Power gain is really not used in audio engineering.ĭo we really need power (energy) amplification? Leave that to the telephone companies or the transmitting aerials (antennas). If we consider audio engineering, we are usually not interested in power.ĭo not ask what power amplification means. Using voltage we get: Level in dB: L = 20 × log (voltage ratio) This naturally leads to sign errors when entering numbers. In physics, attenuation is regarded as a positive value. L = 20 × log (voltage ratio V 2 / V 1) in dB. The amplification or the damping in dB is: V 2 / V 1 or V out / V in means the ratio. V 2 > V 1 or V out > V in means amplification. In analog audio engineering we deal only with 'voltage' amplification (gain) and damping (loss). The program is indicated, but the actual function is missing. The damping factor, also called loss, is the extent to which a device reduces the strength of a signal.Įnter two values and press the right calculate bar in the line of the missing answer The used Browser supports no Javascript. The amplification factor, also called gain, is the extent to which a device boosts the strength of a signal. Resistors) or volume controls, that allow you to adjust the incoming signal to the Gain controls on an amplifier are basically just small potentiometers (variable Gain is the ratio between the magnitude of output and input signals. Calculation : Amplification ( gain ) and damping ( loss )Īs factor ( ratio ) to the level in decibels ( dB ).DupeZap is the easy way to search and remove duplicates that slow your Mac down.
