Abstract: The operation of airports results in environmental impacts associated with high levels of different noise. These may have severe and negative effects on surrounding residents. Aircraft noise is a significant and critical component of the aviation global economic infrastructure. If there is to be growth in aviation, the environmental impacts of aviation must be mitigated. In this paper, a model for the noise pollution of IKIA has been calibrated with the use of noise forecasting software. The calculated model is based on operations and flight data recorded by the airport. The flight data include the type and number of aircrafts, number of runways, etc. which depend on day-time and night- time operations. The results of this model explain the land use of airport and finally explain some methods for decreasing the effects of noise pollution of airport like enforcement of appropriate environmental regulations on the airliners.
