Development of methodology for the industrial noise control in the case of the dedusting system of a foundry

Abstract

The article presents the methodology for industrial noise control in the case of the dedusting system of a foundry. The developed methodology starts from the fact that noise protection is possible at the source of noise itself, on the paths of sound waves, and at the place of reception. The model for noise prediction is the basis of the methodology for solving specific examples, which consists of two parts, the source model and the noise propagation model. The result of the model is a noise field, based on noise map creation time. The activities in the procedure of noise protection are defined on a concrete example, and their interdependence is determined. Designing a noise protection system involves taking into account several functional, technological, and other limitations. Based on the required noise reduction of 15 dB in the nearest residential unit, variant noise protection solutions have been formed. The selection of the final noise protection solution was based on the techno-economic analysis.
