AbstractThe influence of noise from night flying on electro-biological reactions and on the secretion of catecholamines (adrenaline and noradrenaline) was studied in eight healthy adults whose place of residence exposes them to day-time aircraft noise. The interrelationships were then analysed, with daytime noise exposure, personality traits and general day-to-day condition reflected in control variables. The subjects were each observed during five nights without noise exposure (Leq < 32 dB(A)) and five nights with noise exposure (Leq = 36 to 56 dB(A)), when the following factors were varied: number of flights (16, 32, 64 overflights with a constant maximum indoor sound level of 75 dB(A)); and sound level (64 overflights at a maximum indoor sound level of 55, 65 and 75 dB(A)). All these flights were transmitted electro-acoustically between the third and sixth hours of the night. When the various daytime exposures are taken into account, significant mean value differences between noisy and peaceful nights are demonstrated in 8-hour urine for both catecholamines. In the case of adrenaline, the original data already showed a significant increase with noise exposure. Furthermore, catecholamine concentration increases with sound level. The analysis confirms a close link between the volume of adrenaline in the urine collected and electro-biological reactions, with consideration given to personality traits and day-time alcohol consumption.
