# Study of Noise Effect of Slag Storage Technology on Surrounding Environment
## 4 Conclusions  
The authors proposed a methodology for solving the problem of slag storage technology noise. With this methodology, the problem of the acoustic quality of the territory was solved, calibration measurements were made at the source and in the assessed territory, hygiene values were recalculated, and a mathematical model was created that was calibrated according to the results of real measurements. The measures were then proposed, and these were subsequently simulated in the software. A new way of limiting the spread of noise in the environment was created, where, instead of standard mechanical elements (antinoise walls), the slag created in the production process and stored was used.  
In order to address the issue of noise from the slag pots deskulling at the metallurgical plant landfill, three solution options were proposed and compared with the baseline scenario (current state). Each of the proposed options had several sub-options proposed, differing mainly in the geometry of the proposed solutions.  
Based on the noise measurements carried out, the prediction made for the solution of the acoustic situation in the village (measurement point M3) for option 3 was recommended for implementation in the form of a gradual construction of the planned landfill in such a way that the stored slag would form a noise barrier.  
Since the result of the proposed option will only influence the acoustic situation in the villages at a height of 10 m, it is recommended that organizational measures be applied in the meantime so that the permissible noise levels are not exceeded. We recommend that the organizational measures should be developed into a directive that recommends the operating conditions of the landfill based on measurements and calculations.  
We also propose to implement an optimization of the landfill site construction in terms of sound propagation, which would result in improving the acoustic situation in the village as quickly as possible and in achieving non-exceedance of the permissible values of the noise determinants.  
The scientific contribution of this manuscript lies in the fact that the authors used the slag material itself, which was only stored, for antinoise measures and used its acoustic properties. It was measured and simulated in many variants and proved to be a successful methodology. Clearly, the true performance of any barrier depends heavily on the influence of the ground, the atmosphere, and reflective surfaces in built-up areas. Therefore, further work on the on-site performance of barriers will be carried out to validate their performance under carefully monitored outdoor conditions over a wide range of distances [31; 32; 33].  
The results achieved by this work indicate that the barriers obtained with the help of slag can be used to mitigate the noise caused by the operation of the metallurgical plant and thus prevent the spread of noise to outside spaces, so they can be a valid substitute for traditional barriers. It shows that industrial waste material can be effectively utilized as sound absorption material and can assist in mitigating noise pollution. Further developments could be the comparison of traditional barriers with such alternative metamaterial barriers.
