“…However, the magnitude of the electric field depends on the voltage, and not the transmission load of the power line, and any effect on animal behaviour should not vary with transmission load. Increased noise from corona at higher transmission load remains a possibility, but overall dry, clear weather during the experimental period made it difficult to test specifically for effects of corona noise, which is related to electrical discharges in moist weather [46,47]. The model selection showed that ambient relative humidity could not explain much of the observed behaviour patterns (Tabels 5-8).…”

“…1) registered data by means of an all-weather microphone [5] In the authors' previous papers [1,4,6,7], several versions of the feature vector parameters were presented, and the proper selection of the feature space was extensively discussed. Finally, the space has been reduced from 19 to 10 elements [4] and contains:…”

“…Measurements of noise from high voltage transmission lines were performed at a 300 kV and a 420 kV line in Nordmarka, north of Oslo, Norway. Measurements were done during rainy weather at temperatures of 0 -4 °C, weather conditions with high levels of corona noise (Engel & Wszolek, 1996). The sound pressure level (dB re.…”

“…Most noises are not stable in intensity over wide frequency bands but vary in amplitude, and the hearing threshold for such noises measured over a continuous spectrum have been reported to be similar to pure tones (Kinsler & Frey, 1962). Since corona noise from power lines does not have a stable intensity over the one-octave frequency bands (Engel & Wszolek, 1996), the hearing threshold for pure tones could be used as an estimate of the hearing threshold for the noise.…”
