NOISE MAPPING FOR SABIHA GOKCEN AIRPORT USING IMPACT TOOL

With the increasing demand for air transportation, the volume of air traffic continues to rise, significantly affecting individuals living near airports and airport employees due to noise generated by aircraft. Airport noise varies depending on factors such as the intensity of flight traffic, the types of aircraft landing and taking off, and the engine technologies employed in these aircraft. Exposure to airport noise can lead to adverse outcomes for those affected, including reduced quality of life, headaches, anxiety, depression, and elevated stress levels. This study aims to generate noise maps for Sabiha Gökçen Airport, one of Turkey’s busiest airports in terms of traffic volume, which is currently situated within residential areas. A dataset comprising real traffic data from a specific day, incorporating a mix of different aircraft types, was utilized. Noise maps were produced using the IMPACT noise model, developed by Eurocontrol, as a reference based on this dataset. The results quantify significant noise exposure, with a major hospital subjected to 65 dB during arrivals and industrial areas experiencing levels up to 70 dB during take-offs. Furthermore, schools and residential facilities were identified within the 65 dB contour, highlighting the widespread impact on noise-sensitive communities.
