Abstract

The industrial environment of production workshops encompasses a range of harmful and hazardous factors that negatively impact workers’ health and performance. Among these, high levels of noise generated by operating equipment during technological processes are particularly significant. Prolonged exposure of workers to elevated noise levels, exceeding 80 dB, without collective and individual protective equipment, leads to occupational hearing diseases and disruption of other bodily systems. The purpose of this study was to develop protective measures against industrial noise in workshops with operating equipment, thereby improving working conditions. The research employed scientific generalisation and analysis of existing literature on the harmful effects of industrial noise, along with regulatory documents concerning permissible noise parameters in workshops. Permissible noise parameters in the working areas of industrial premises have been substantiated. Based on applicable regulatory acts, scientific recommendations were proposed for the design of a noise-insulating panel to reduce broadband and low-frequency noise using soundproofing and sound-absorbing materials. It has been established that the use of a sound-insulating panel increases the effectiveness of noise reduction in working areas of premises to the level of sanitary standards. The practical significance of the obtained results lies in reducing noise levels in industrial premises through the summary localisation of sound waves and their subsequent absorption within the sound-insulating panel. This allows for the improvement of working conditions in industrial workshops with operating equipment and a reduction in occupational morbidity among industrial workers
