THE OBJECTIVE IN THIS PRESENT WORK IS DEVELOP AN ACOUSTICS BARRIES ANALYSIS METHOD BASED IN THE BOUNDARY ELEMENTS METHOD. THIS METHOD IS ENOUGH EFFICIENT, ESPECIALLY IN ACOUSTICS ENVIROMENT WITH SOUND PROPAGATION. THE SOIL INTERFERENCE IS ONE OF THE IMPORTANT EFFECTS TO BE CONSIDERED IN THE ACOUSTICS BARRIES CASE. THE INSERTION LOSS CAN BE CALCULATED WHEN A BARRIER IS INSERTED BETWEEN THE NOISE SOURCE AND THE RECEPTOR USING THIS PROCEEDING. |
