[0002] With the continuous development of urban rail transit and municipal roads, sound barrier projects are also being implemented as auxiliary noise reduction measures along with the main projects to reduce the impact of traffic noise on residents along the line. In existing sound barrier technologies, transparent glass sound barriers are often used to improve the landscape effect of sound barrier projects.
