WebUsing voltage we get: Level in dB: L = 20 × log (voltage ratio) 6 dB = twice the voltage 12 dB = four times the voltage 20 dB = ten times the voltage 40 dB = hundred times the voltage If we consider audio engineering, we are usually not interested in power. Do not ask what power amplification means. WebIs dBu the same as dB wrt 1 micro Volt (dBµV)? In expressing sensitivity of radio receivers, signal levels are often expressed in dB relative to 1 micro Volt (µV). There is a common practice to write this as dBuV rather than dBµV due to shortcomings of the character set in some contexts. dBµV may be qualified as 'emf' meaning it is the ...
