The Research On The Unified Model Of Aircraft Noise Contours

In recent years, China's air transport has been greatly developed, the aircraft noise problem will become increasingly prominent. China's environmental protection department has been expressly provided that when the new airports are applying for airport construction projects, noise prediction and environmental impact assessment must be taken around the airport, to make the original airport noise exposure map( noise impact area range) and draw the contour. This thesis will combine the experience of home and abroad according to international law, and give the drawing of the airport noise contours.Firstly, this thesis studies the ECAC, ICAO and SAE about the calculation of the single-event aircraft noise, by comparing the advantages and drawback to find out the exact method to draw contour; then describes in detail how to use the INM(Integrated Noise Model) to draw the noise contours. According to the above content, C # development platform is used to design and comply the drawing of the aircraft noise contours, including the tracking of the contour, smooth and fill the contour. The system makes the error correction on the predictive value of airport noise, so that the drawn contour is more accurate. The result of this paper is important to promote the development of the domestic airport noise calculation.
