Open Information and Computer Integrated Technologies

Currently, the topic of research of the aircraft noise influence on the environment is relevant. Aircraft and engine developers are constantly exploring ways to reduce noise following the new standards of the ICAO Committee (CAEP), whose main task is to protect the environment from the effects of aviation, to provide a comfortable environment for people exposed to aircraft noise and harmful substances. By limiting the permissible noise level of aircraft, CAEP initiates aircraft manufacturers to introduce the latest noise reduction technologies in their design. Measurement of aircraft noise is obviously an important type of research not only in the aircraft industry. The existing airports in the course of reconstruction, and new ones at the project development stage, should be mandatory tested on indicators of aircraft noise, which will penetrate into the surrounding area, including settlements of various sizes. Currently, scientists from different countries are making significant efforts to reduce the turbine noise of existing and prospective civil aircraft. Of course, nowadays, external jamming methods are commonly used. At the same time, an important way to reduce engine noise was the widespread use of so-called sound-absorbing structures. This article describes the direction of reducing the level of aircraft noise at the source and on the ground, near airports. To reduce the noise in the source of noise, the ways to reduce the turbulence of the streamlined aerodynamic bearing surfaces are considered by reducing their inductive resistance and matching the flow of gas in power plants. It is shown that the implementation of such approaches in modifications of domestic passenger and transport aircraft gives a positive result. When solving the problem of reducing noise on the ground, the study analyzed the effect of aviation noise on the population living near the airport as an example. The necessity of using soundproofing means in residential areas to reduce noise exposure is shown. An analysis of the effects of noise exposure is given. In conclusion, the preliminary results obtained in the course of research are presented.
