"Quasi-Peak Measurements and their Objective Correlation to Acoustical Annoyance of Corona Radio Noise",
Power Apparatus and Systems, IEEE Transactions on, no. 4: IEEE, pp. 1830–1837, 1971.
AbstractThe levels of annoyance to radio reception caused by ac and dc coronas are calculated using the AF power spectra measured at the AF output of a radio-noise meter. The radio annoyance levels. (RAL) and the AF powers are compared with the corresponding quasi-peak readings. The lack of direct correspondence is ascribed to the fact that the QP readings are not sensitive to the randomness in the corona pulse repetition rate which strongly affects both the AF power spectrum and the RAL of corona.
