DYNAMICS OF AIRCRAFT NOISE IN THE MALINKI WILDLIFE PROTECTION AREA INSPRING AND SUMMER

The noise level at the Malinki Biological Station (Russian Academy of Sciences) near Moscow was studied in spring and summer by the method o f point estimates and ecological and acoustic analyses. Up to 200 airp lanes cross its airspace every day; sometimes they fly as often as 30 airplanes per hour. Flights at low altitudes accounted for a noise lev el of 75-90 dB during 6 h per day. The noise level was unstable due to meteorological, ecological, and social conditions. To further clarify this issue, ecological studies, as well as the additional analysis of noise level and sources, are required.
