本指导材料的目的是为各州提供关于实施平衡的噪声管理方法的建议和实用信息。国际民航组织大会于2001年采用的平衡方法包括四个主要要素:减少源头噪音、土地使用规划和管理、减少噪音的操作程序和对飞机的操作限制。本指导材料描述了每个要素下可用的一些措施、它们之间的相互关系，以及可用于评估和比较其成本和效益的工具。

The aim of this guidance material is to provide States with advice and practical information on implementing a Balanced Approach to noise management. The Balanced Approach, which was adopted by the ICAO Assembly in 2001, encompasses four principal elements:reduction of noise at source,land-use planning and management,noise abatement operational procedures andoperating restrictions on aircraft.This guidance material describes some of the measures available under each element, their interrelationship, and the tools that might be used to assess and compare their costs and benefits.
