Abstract
Laboratory experiments and field measurements were carried out to determine relevant acute and long term effects of noise from low-flying military aircraft. Acute effects on the cardiovascular system were established under simulation conditions. Blood pressure, heart rate, and biochemical stress parameters (cortisol and catecholamines, renin and free fatty acids in blood) were measured as a function of time. Long-term effects of noise from low-flying aircraft were analyzed in 10 to 13-year-old children by comparative studies including a 75 m low-altitude flight area and a neighbouring area with flight altitudes of 150–450 m. Significantly higher blood pressure values were found in girls in the 75 m area. The hearing thresholds were significantly increased in boys and girls in the 75 m area. Altogether, acute effects of noise from low-flying aircraft on cardiovascular functions and hearing ability could be proved, and potential risks of long-term exposure to low-altitude flight noise are discussed.
