Psophometric voltage
Psophometric voltage is a circuit noise voltage measured with a psophometer that includes a CCIF-1951 weighting network[?].
Note 1: "Psophometric voltage" should not be confused with "psophometric emf," i.e. , the emf in a generator or line with 600Ω internal resistance. For practical purposes, the psophometric emf is twice the corresponding psophometric voltage.
Note 2: Psophometric voltage readings, V , in millivolts, are commonly converted to dBm(psoph) by dBm(psoph) = 20 log10V- 57.78.
