民用机场航空器噪声影响评价关键问题及对策

为了更好地指导民用机场航空器噪声环境影响评价实践，对机场航空器噪声影响评价案例进行分析与总结，发现航空器噪声环境影响评价工作中存在评价范围确定合理性不足、噪声标准适用性不强、噪声预测模式相对落后及噪声防治措施不全面等问题。针对以上问题，推荐了合理的评价范围划定方法、噪声评价标准，提出了噪声预测模式发展方向，汇总了较全面、较先进的噪声防治措施，并针对未来航空器噪声影响评价提出了建立我国航空器噪声源数据库、开发航空器噪声预测软件及加快制定适应性强的技术导则和标准等建议。

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.
