dBV(decibel volt)
“dBV” stands for “decibel Volt”, and it is used to express voltage in dB units. dBV represents voltage using a logarithmic scale based on a reference of 1 Volt (V), and it is measured in terms of RMS (Root Mean Square).
A value of 0dBV corresponds to a reference voltage of 1 Volt. Positive dBV values indicate voltages higher than the reference, while negative dBV values denote voltages lower than the reference.
In other words, when the voltage is 1V, it is represented as 0dBV.
dBV is primarily utilized in the field of acoustics, especially to depict consumer-level audio signals. -10dBV has been adopted as the reference level for consumer audio.
