abstract:
In view of the disadvantage of poor weather resistance of current sound barrier, this paper used polyurethane filling as alternative filling. It not only improved the weather resistance, but also ensured the sound absorption coefficient and sound insulation of the barrier. At the same time, TUP dust-proof membrane was used to improve the sound absorption coefficient. This work is a breakthrough in acoustic performance research of high-speed railway sound barrier, has great reference value for studying the use of membrane to improve the sound absorption coefficient.
