AIRCRAFT NOISE AND METHODS OF ITS REDUCTION

Abstract

Aircraft noise and methods of its reduction are considered. Brief information about noise sources and acceptable value are described. Regulatory documents, the noise standard established by ICAO are also considered. Recommendations for reducing aircraft noise are presented.
 The whole body is susceptible to noise. Even at a relatively low, but constant noise level, a person may experience discomfort, irritability, and headaches. Especially dangerous is sudden noise that violates the psychological comfort of a person (takeoff and landing, areas of the route of supersonic aircraft).
 The result of the specific effects of noise on the hearing organs are diseases such as sensorineural hearing loss, manifested by persistent hearing loss. The development of sensorineural hearing loss is associated with prolonged and regular levels of aircraft noise.
 Pilots are exposed to this noise level, the noise level fluctuates in the range of 90-109 dB, and in the cockpits of helicopters - in the range of 100-118 dB.
 Aircraft noise around airports and airways covers the entire area of ​​the territory, including the residential area. When the airport is close to the city, there are problems associated with a high level of aircraft noise, which creates discomfort for the human body.
