Environmental Noise From Mineral Extraction Sites - Comparison of Predicted and Measured Levels

“…Detailed sizes, internal absorptions and transmission losses for all walls of these buildings were also input to the program, as were detailed contour maps of each site via a diy'tizer. Four calculation modules are available within ENM;-standard ENM, CONCAWE [7], BBN-EEI [8] and NORDFORSK [9], and predictions were made with all four, although only the ENM and CONCAWE modules cater for the e eets of wind, temperature and humidity in any detailr Figures 3 and 4 show the results of single point calculations using the ENM and CONCAWE modules at the two monitoring positions for the rst site. Figures 5 and 6 show the results of similar calculations for the second site.…”
