The Study Of Airport Aviation Noise Active Reduction Method

Along with the expansion of civil airport's number and size and the expectation is improved by nearby residents to living and working environment quality, the issues about the impact of airport aviation noise become increasingly prominent. Research, explore effective airport aviation noise reduction methods are of great importance and have the long-term significance to the sustainable development of civil airports and the improvement to the sound quality of the environment around the airport public, it also play an active role to eliminate and mitigate the social disputes which caused by airport noise.Firstly, introduces the characteristics and hazards of airport aviation noise, reviewed the status of domestic and foreign airports about implementation and research of active noise reduction; secondly, these is a research of basic theory on the active noise reduction, which include evaluation analysis and construction of calculation model of the airport aviation noise.Third, proposes a variety of airport active noise reduction method which is feasible, including aircraft selection, adjust the aircraft mix, adjusting flight schedule, the use of noise abatement flight procedures, runway using alternatively, taking economic measures, such as the establishment of a general model of airport noise charges. Finally, take Guangzhou Baiyun International Airport as an example, with the INM software that will be applied to all kinds of active noise reduction method of the Guangzhou Baiyun International Airport, taking the shape of the noise contour maps, noise area, noise sensitive point value as the measure of the noise, the actual effect of the active noise reduction were quantitatively analyzed. The airport noise charges common model are applied in Guangzhou Baiyun airport, and the airport ' s specific noise charges standard is obtained.
