Level in dBu to dBV, or volts (rms), and dBV to dBu, or volts (rms) volts (rms) to level in dBu and dBV p-p = peak to peak Conversion of sound units SPL (levels) Conversion of factor, ratio, or gain to a level value (gain decibels dB)Level...
So a "power amplifier" which needs an input of 1.5 V from a 1000 ohms source to give an output of 30 V into 8 ohms is spoken of as having a gain of 20 × log (30/1.5) = 20 × log (20) = 20 × 1.3 = 26 dB. So "dB" is simply another way to write "ratio of"....
To use the calculator, simply enter a value. The calculator works in both directions of the ↔ sign. Transfer factor Europe + Intern. mV/Pa (1 mV = 0.001 V) ↔ Sensitivity Europe + Intern. dB re 1V/Pa Transfer factor = 10Sensitivity / 20 Sensitivity in dB re 1 volt per pascal...
To each noise potential the temperatureTand the bandwidthΔf must be indicated, with which it was measured. To use the calculator, simply enter a value. The calculator works in both directions of the↔sign. Noise voltage level (audio)Lu ...
