Research on Control Effect of Window Glass on Inner Sound Environment of High-speed Train

摘要

As the problem of noise inside high-speed train becomes increasingly serious, the window glass of high-speed train must have better sound insulation performance to block the external noise. In this paper, the sound insulation of different single-layer glass, laminated glass and hollow glass are compared and analyzed basing on a statistical energy model of side window glass for high-speed train, and the sound insulation properties are summarized. The sound insulation performance of windows with different edge sealing materials is analyzed. It is found that the window with combined edge sealing materials have better sound insulation performance, which provides certain reference for the optimization of the window glass structure of high-speed train.
