Description
Summary:The article presents process of modeling and generating noise contours and focuses on how to calculate aerodynamic noise levels around ports and airports. In order to have information about the magnitude and magnitude of the impact caused by aircraft noise around airports / ports, maps that have marked outline contours are needed. A noise contour is generated by the mathematical calculation of the areas where there are noise indices and is marked by a line along which the index value is constant. Calculation of the value of the noise index is made by summing up all the acoustic events caused by the aircraft (individual) occurring over a period of time, normally expressed in days or months.
