title: [Aircraft noise: changes in biochemical parameters].
abstract: The effect of stress caused by aircraft noise was studied on 14 female and 11 male volunteers, who were of a age ranging from 21 to 42 years and of a mean age of 25 years. The volunteers were exposed to an aircraft simulator that stimulated the low level flight of an air force plane and produced a maximum noise level of 105 dB(A) for 3 sec. in a short time. Before and immediately after the exposure, the concentration of ACTH was measured by means of a radioimmunoassay. The ACTH is a hormone, responsible for initiating a chain reaction that is characteristic for a stress reaction. In 100% of the cases the concentration of this hormone increased. It reached a pathological level in 28% of the cases. The effect on the lipid metabolism was expressed by an increase of total cholesterol and a decrease of the triglycerides in the serum. A slight increase in blood sugar which, together with the free fatty acids, is relatively quickly reduced to energy, could be determined. The aircraft noise did not influence the activity of the liver transaminases in any way. A short-term exposure to aircraft noise is able to stimulate a stress reaction, whereby, the determination of the ACTH offers valuable informations.
