摘 要: 将华南理工大学戴然捷等人在厦深铁路和武广高铁测得的高速铁路交通噪声的频谱经A计权和归一化,计算出多种常用隔墙构造对其的空气声隔声频谱修正量。通过计算验证,得到了针对高铁交通噪声的频谱修正曲线,以期完善相关隔墙隔声性能评价体系。 In this paper,the spectrum of high-speed railway traffic noise measured by Dai of SCUT on the Xiamen-Shenzhen railway and the Wuhan-Guangzhou high-speed railway is A-weighted and normalized to calculate the airborne sound insulation spectrum corrections for various commonly used partition wall structures.Through calculation and verification,a spectrum correction curve for high-speed rail traffic noise is obtained,in order to improve the relevant sound insulation performance evaluation system of the partition wall.
