摘要： A vibration-damping section with sound absorbing material includes a sound proof panel, sound absorbing material fixed on one surface thereof and vibration damping material stuck on the top surface or the bottom surface of the sound proof panel one surface of the sound absorbing material which is the opposite side of the sound proof panel can be covered with a porous panel, if necessary, and moreover a joint is provided for hanging and connecting sections for closely connecting themselves one another in a width direction. Since the vibration-damping section with sound absorbing material according to the present invention has above described structure, in particular, it can be fixed on the bottom surface of an elevated bridge and has a sound insulating effect of the radiated noise which are caused by the elevated bridge structure and a sound absorbing effect of the reflected noise and moreover has a vibration damping effect of decreasing occurrence of the secondary noise by reducing the vibration of the sound absorbing panel.
