Abstract: The subject of this study is the safety of vital activity of the flight and engineering-technical personnel of state aviation. The object of this study is the acoustic safety of professional activities of the flight and engineering-technical personnel of state aviation. The authors meticulously examine such aspects of the topic, as the assessment of working conditions of the flight and engineering-technical personnel of state aviation considering the noise and infrasound; risks of reducing the overall and professional performance due to the impact of the acoustic factor; as well as reliability of the flight and engineering- technical personnel of state aviation. Methodology of the research combines the methods of engineering acoustics, reliability theory, aviation medicine, occupational medicine, ergonomics, and probability theory. The main conclusion consists in substantiation of the need for developing and implementing the special means and methods to ensure the acoustic safety of professional activity of the flight and engineering-technical staff of state aviation as an integral part of the system for providing the safe aircraft operation. It is demonstrated that the system for preventing the negative impact of noise upon the aviation personnel must be comprehensive, as well as include technical and organizational measures, monitoring of the working conditions of flight and engineering-technical personnel, availability and proper application of the individual and collective noise protection, dynamic medical supervision over the flight and engineering-technical personnel of state aviation, with the implementation of a complex of medical-preventive and health-improving measures.

Abstract: The research subject is acoustic safety of aviation specialists’ activities, including the analysis of the peculiarities of use of the audio channel of the aviation ergatic system management, the functional reliability of the operator of the aviation ergatic system, the sources of aviation noise, the ways of modeling of the noise impact on the reliability of the operator, the crews of modern aircrafts and the physiological mechanisms of impact of aviation noise on the operator of the aviation ergatic system. The novelty of the study is determined by its system character and orientation on the detection of the problems of safety of professional activities of aviation specialists, conditioned by the impact of aviation noise. The research methodology combines the methods of the reliability theory, hygienic studies, occupational medicine, evidentiary medicine, mathematical statistics and engineering acoustics. The authors formulate the particular problems of safety of professional activities of aviation specialists, determined by the impact of aviation noise. The study shows that aviation noise is the source of potential danger, causing the higher risk of misactions of aviation specialists and the danger of occupation diseases, causing the early professional disqualification. The research results show the urgent necessity to develop and implement special means and methods of improvement of acoustic safety of aviation specialists’ professional activities as an integral element of the safe operation of air transport.
