累积事件飞机噪声评价指标改进研究
Research on Improving Aircraft Noise Metric of Cumulative Event
摘要
Abstract
Reasonable selection of noise evaluation index is an important prerequisite for airport noise assessment and control. The typical noise evaluation indexes of some countries and regions were analyzed, and their com-monalities and differences were summarized in this paper. To solve the problem that the weighted equivalent continuous perceived noise level in China was in disunity with the acoustic environment noise metric, a new noise metric of cumulative event was proposed. Aiming at the fact that the existing metrics, to a certain degree, neglect the influence of night noise event, a new night assessment metric was put forward. Finally, a case study based on the data of Guangzhou Baiyun International Airport was carried out to verify the effectiveness of the e-valuation metrics. It maintains the results are of reference value.关键词
