MODELING OF THE PROPAGATION OF AIRCRAFT NOISE, TAKING INTO ACCOUNT THE DIRECTION OF ITS ACOUSTIC RADIATION

Statement of the problem. The increasing levels of noise pollution caused by infrastructure development and growing traffic flows, particularly aviation traffic, have become a serious environmental and social issue. Excessive noise levels negatively affect human health, leading to physiological and psychological disorders and reducing the quality of life. In this context, the study of noise conditions at sites requiring protection from acoustic impacts is of particular relevance. Methods of research. This paper examines the methodology for predicting and assessing noise pollution using modern computational modeling tools. Specifically, the “AcousticLab” software package is utilized, based on the principles of applied acoustics, enabling the analysis of sound wave propagation processes in various environments. The primary focus is on modeling aviation noise, one of the most prevalent sources of acoustic impact in urban areas and near airports. The research results demonstrate the possibility of creating detailed models of noise propagation that take into account geometric and physical features of the area, types of noise sources, and their characteristics. This approach allows for accurate calculations of acoustic impact levels, prediction of their spatial distribution, and assessment of risks to public health. Scientific novelty. The proposed methodology provides instrumental support for developing noise protection strategies, including designing screens, barriers, and optimizing spatial planning of territories. Thus, the use of the “AcousticLab” software package enhances the effectiveness of noise monitoring and management, minimizing the negative impact of noise pollution on humans and the environment.
