Key issues and countermeasures of aircraft noise impact assessment in civil airports

In order to guide the environmental impact evaluation practice of aircraft noise in civil airports, by analyzing and summarizing the cases of airport aircraft noise impact assessment, it was figured out that there were some problems in aircraft noise environmental impact assessment, such as insufficient rationality in determining the assessment scope, the weak applicability of noise standard, the relative backwardness of the noise prediction model, and the non-comprehensive of noise prevention and control measures. In view of the above problems, the reasonable evaluation-scope delimiting method and noise evaluation standards were recommended, the development directions of the noise prediction model were proposed, and more comprehensive and advanced noise prevention measures were summarized. The suggestions were given on future aircraft noise impact assessment, such as establishing an aircraft noise source database, developing aircraft noise prediction software and speeding up the formulation of technical guidelines and standards with strong adaptability.
