Abstract
Modeling of interferometric noise barriers for railway transport in China
Incoming article date: 08.11.2025To evaluate the noise suppression efficiency of railway transport screens, the COMSOL Multiphysics software package (module "Pressure Acoustics, Frequency Domain") was used in this article. Using the finite element method, calculations were carried out and the sound insulation characteristics of noise protection screens were assessed, and a comparative analysis of the characteristics of various screen models was also carried out. Based on the effects of acoustic interference, an interference-type noise suppression device is proposed, in which filling the upper part with a porous material improves the diffraction sound absorption of the noise protection screen, thereby enhancing its acoustic characteristics.
