NOISE LOAD MODELLING
Abstract
The noise propagation an alysis is critical in noise lo aded areas for a remedy search. Very useful tool for these analyses is mathematical modeling. Any modeling of a real world scenario has to consider a number of input data, noise sources, the landscape over which the noise is propagating and the location of the receivers. All these input data has a spatial character and that’s why it was decided to perform the noise propagation modeling in the GIS environment. A noise pollution modeling takes the geometry from the Geo-database together with the source definition and calculate s the spatial noise distribution over the observed area. The geom etry needs to be in stalled in the Geo- Database as a 3 dimensional model of the worl d with all objects in place that influence the propagation of the noise. The results of th e calculations are written into spatial data files. Results then can be visualized, analyzed and presented effectively using GIS. Most of the model algorithmization and verification was performed in works of environmental engineering students of VSB-TU Ostrava.
