Reduction of vibroacoustic effect of high-speed trains

摘要

Increase of train speeds induces increased levels of vibration and structural noise in residential areas. The experimental plots were laid with different types of vibration isolation at the ballast base. It is shown that the polyurethane ballast mats are 1.9 times more effective than two layers of geocomposite and 1.5 times more effective than the porous rubber mats. Application of ballast mats significantly reduces vibration and noise in buildings near the railways.
