机场附近隔音玻璃隔声性能对比测试研究
Comparative Test of Sound Insulation Performance of Soundproof Glass near an Airport

作为外立面建筑围护结构，玻璃外窗在建筑的隔声体系中起到了关键的作用。对于机场附近的建筑而言，普通玻璃通常难以抵挡飞机起降时所带来的噪音影响。本试验针对机场噪声特点，通过在超静音隔音试验箱中搭配不同的隔音玻璃在机场附近进行了隔声量测试研究。机场噪音监测结果表明，机场周围不同机型所造成的噪音变化量基本一致，且最大噪音量均在85~90 dB之间；通过对不同类型的隔声玻璃进行测试分析，得出相同质量下全钢化真空玻璃的隔声性能大于夹胶玻璃大于中空玻璃，是机场附近建筑玻璃的最优选择；对真空玻璃进行配置优化，通过对其复合阻尼层、中空层并优化玻璃板厚度排布方式，优选出钢化真空复合玻璃A-Mute1，且实测其平均隔声量可达50 dB以上，符合建筑标准的要求。
As the exterior facade building envelope, the glass exterior window plays a key role in the sound insulation system of the building. For buildings near the airport, ordinary glass is usually difficult to resist the noise impact caused by aircraft takeoff and landing. According to the characteristics of airport noise, the sound insulation capacity was tested and studied near the airport by matching different sound insulation glasses in the ultra quiet sound insulation test box. The airport noise monitoring results show that the noise changes caused by different aircraft types around the air-port are basically the same, and the maximum noise levels are between 85 and 90 dB; Through testing and analyzing different types of sound insulation glass, it is concluded that under the same quality, the sound insulation performance of fully tempered vacuum glass is greater than that of laminated glass and greater than that of insulating glass, which is the best choice for building glass near the airport; The configuration of vacuum glass is optimized. By optimizing the composite damping layer, hollow layer and glass plate thickness layout, the tempered vacuum composite glass A-Mute1 is optimized. The measured average sound insulation is more than 50 dB, which meets the requirements of building standards.
