现有的机场噪声评价指标主要是针对固定翼飞机设计的，并不能很好地反映军用直升机噪声对机场周围目标的影响。首先分析了军用直升机机场噪声的特殊性，然后研究了现有机场噪声评价指标的内涵和联系，最后采用最大噪声级L Am ax和加权等效连续感觉噪声级L WCEPN联合评价的方法对军用直升机机场噪声进行评价。该联合评价方法可以同时反映总噪声级与单次突发噪声的影响，能较为完备地对军用直升机场噪声进行评价。实测案例表明，此方法能更准确有效反映附近居民对噪声影响的感受。

The existing methods to evaluate the airport noise are mainly designed for fixed wing aircraft.In view of the different characters of military helicopter noise,these methods have some shortages and the noise evaluation index can not reflect the whole influence of military helicopter noise on the environment. In order to solve this problem,the characteristics of the military helicopter noise are discussed and the ex-isting index is analyzed.And then a method of multi-index evaluation to evaluate the military helicopter airport noise is proposed by using LAmax and LWCEPN at the same time.This multi-index evaluation method can reflect both total noise level and single burst noise at the same time.The test result shows that this method can reflect the real feeling of the neighbor residents about the noise,which verifies that this multi-index evaluation method is more effective.
