机场附近的噪声环境和住宅的隔声改造

对首都机场的飞机机型和机场附近住宅的噪声现状进行监测，采用计权等效连续感觉噪声级和昼夜等效声级对室外的飞机噪声进行综合评估，提出关于机场周围建筑物隔声标准和方法的建议。以首都机场周边某住宅为例进行隔声治理，飞机起飞经过13 s时室内外开关窗的噪声值和室内现场隔声量的测量结果表明，居民对房屋隔声效果反应良好，隔声后改善了居民住宅内的声环境质量。

Noise Environment and Sound Insulation of Residential Building in the Vicinity of Capital International Airport

In recent years, complaints about aircraft noise have been increasing. In this paper, the measures for noise insulation and reduction of residential buildings in the vicinity of airport is reviewed and discussed. Aircraft noise of the Capital Airport and the characteristic of noise around the residential buildings near the airports are monitored. The weighted equivalent continuous perceive noise level and the day-and-night equivalent sound level are applied together to assess the effect of aircraft noise. Some standards and measures for sound insulation of the buildings around airports are also suggested. Taking a residential building near the capital airport as an example for sound insulation and reduction, the noise level outside and inside the building is measured in 13 seconds after airplane taking off, and the sound insulation volume inside the building is also tested. The results show that sound insulation measures for residential buildings can provide a comfortable, quiet, intimate acoustic environment.
