摘要： 随民航事业的蓬勃发展，机场周围的飞机噪声问题已变得不可小觑。基于噪声源研究已相当成熟，本文从飞机减噪程序入手，研究国内外常见的几种进近减噪程序，重点探索研究大角度（6度角）飞机进近减噪程序,结合国际民航组织的相关研究项目，用飞机着陆噪声区域面积的减少来阐述大角度进近的潜在益处。

Abstract:

With the development of civil aviation industry, the aircraft’s noise around the airports has been becoming a serious problem. In this paper, several domestic and international noise reduction procedures are studied. The attention is paid mainly to the steeper (6 degrees) approach noise reduction procedures. The potential benefits of the steeper approach are evaluated by the reduction of the area covered by the noise of aircraft’s landing. This work is a part of the project supported by the International Civil Aviation Organization (ICAO).

Key words: acoustics, steeper, noise reduction, approach
