On this screen, enter a Name and an optional Description to explain the purpose of the Custom Dimension to other Decibel users. As mentioned above, decibels are logarithmic units with a base of 10. Truly cannot believe I’ve just seen Grosjean walk away alive from that, an utterly horrendous moment. RME Audio Technology explained. A +1dB difference in level is equivalent to the power of the original signal being multiplied by 10^1/10 (≈ 1.259). Services Details about the services we provide. You could simply put “blog” into the text box having selected Contains and all users who viewed a URL containing “blog” will match this criteria. This is where the decibel comes along to make things easier: we tack a letter onto the end of dB—dBu, dB SPL, etc.—and suddenly we have a shorthand that carries the calculation we’d make given the variables we know. A decibel (dB) is defined as 20 times the base-10 logarithm of a ratio between two voltage levels V out /V in (voltage gain, in other words). See Cookie Policy for more details. For example, starting with 27 dB: \(27 \div 10 = 2.7\) Now take the inverse base 10 logarithm of 2.7: Dans les schémas ci-dessous, calculer le gain ou la puissance, 2) -6 dB correspond à un rapport de 1/4 ; P = 20 / 4 = 5 W. Le triangle représente un circuit dont le gain est donné en dB. Dans ce cas, la mesure de la puissance se fera sur les pointes d’amplitude ce qui amène à définir la puissance crête appelée aussi puissance de pointe de l’enveloppe (ou PEP, Peak Envelope Power en anglais). Si le gain exprime un rapport de tensions, le gain est doublé par rapport aux mêmes valeurs exprimées en watts.
