Study on the noise prediction in mining and industrial plants

الملخص EN

Noise Levels (NL) in mining and industrial plants were investigated.

Three mining and industrial projects, namely: Assiut Cement plant, Assiut Cement Quarry and El-Gedida mine were selected SL-130 and Bruel & Kjaer, Type 1625 sound level meters at the selected points away from the sources were used to measure the noise level.

Numerical prediction models for noise level; ISO and VDI were applied.

The differences between the measured values and the predicted ones using these models were compared in order to evaluate the accuracy of these models.

The results of the field measurements at the three areas showed good agreement with the results of the noise prediction models.

The results obtained indicated that; (a) the sound pressure levels were higher than the acceptable level at El-Gedida mine and lower than that at the other two areas, and (b) the measured noise levels at the management building and the workshop area in El-Gedida mine were higher than the acceptable level for the administration areas.

Therefore, control measures are required in these projects to keep the environment safe.
