The invention relates to the technical field of sound barriers, in particular to a suspended closed sound barrier for an urban rail. According to the technical scheme, the sound barrier piece comprises an outer steel plate, sound absorption cotton, a resonance sound absorption steel frame, an elastic piece and a partition plate, the side portion of the sound absorption cotton is fixedly connected with the resonance sound absorption steel frame, the side, away from the sound absorption cotton, of the resonance sound absorption steel frame is slidably connected with the outer steel plate, and a rubber pad is fixedly installed on the side portion of the resonance sound absorption steel frame; the side portion of the sound absorption cotton is fixedly connected with an elastic piece, the other end of the elastic piece is fixedly connected with a partition plate, and the partition plate is fixedly installed in the middle of an external steel plate. The sound-absorbing cotton and the resonance sound-absorbing steel frame move towards the partition plate, the sound-absorbing cotton and the resonance sound-absorbing steel frame are used for squeezing air into the space between the right side of the partition plate and the external steel plate, and therefore the air pressure in the space is increased, the air pressure is used for resisting wind pressure, the wind pressure influence is reduced, and sound insulation of the sound barrier is not affected.
本发明涉及声屏障技术领域，尤其涉及一种悬挂封闭式城轨用声屏障。其技术方案包括：声屏障件，包括外部钢板、吸音棉、共振吸音钢架、弹性件和隔板，所述吸音棉的侧部与共振吸音钢架固定连接，所述共振吸音钢架远离吸音棉的一侧与外部钢板滑动连接，所述共振吸音钢架的侧部固定安装有橡胶垫，所述吸音棉的侧部与弹性件固定连接，所述弹性件的另一端与隔板固定连接，所述隔板固定安装在外部钢板的中部。本发明通过吸音棉和共振吸音钢架向隔板移动，利用吸音棉和共振吸音钢架将气体挤入隔板右侧与外部钢板之间，从而增大该空间内的气压，利用气压抵抗风压，降低风压影响且不影响声屏障的隔音。
