Research into Possibilities of Reducing Noise Emissions in the Sandy Gravel Production Process—Case Study

The continuous process industry is an important area of the economy. In addition to its undeniable societal benefits, its operation is associated with several factors that are often perceived negatively and have an adverse impact on the environment, noise emissions being one of them. Accordingly, noise emissions have been the subject of numerous studies and always have to be approached in the context of a specific industrial area. In this paper, a case study is presented to illustrate the results of research aimed at reducing noise emissions in the sandy gravel production process. The research identified causes and effects of noise emissions arising from the gravel treatment process. Based on these, practical solutions were subsequently investigated and proposed, and their implementation brought noise emissions below 50 dB. The results obtained during the research can be generalized for further study of the issue and can be used to make general valid recommendations applicable in the continuous process industry.
