Assessment and Modeling of Environmental Noise From Open-Air Concerts in a Student Residential Area

Abstract

This paper presents the results of a comprehensive study on the assessment of environmental noise levels at selected locations used for public events in the city of Banja Luka. The research was conducted with the aim of evaluating the impact of noise on the environment and public health, as well as determining compliance of the measured noise levels with applicable legal regulations and the recommendations of the European Union and the World Health Organization. The study includes a theoretical analysis of the physical and physiological characteristics of sound and noise, their propagation in space, perception, and effects on the human organism, as well as a review of the relevant legislative framework. Field measurements were carried out at several representative locations using standardized measuring equipment and prescribed methodologies, and the obtained results were analyzed and graphically presented through noise propagation models. Based on the results, conflict areas with elevated noise levels were identified, and specific urban planning, technical, and organizational measures for noise reduction were proposed. The noise modelling results enabled the definition of a noise protection zone and a maximum permissible sound emission level of 78.5 dB(A) for open-air concert organization in the studied student residential area. The conclusions of the study provide a professional basis for the development of decisions and action plans aimed at sustainable noise management during public events and the improvement of quality of life in the urban environment.
