The invention discloses an underground traffic track noise reduction device, and belongs to the technical field of underground track traffic. The underground traffic track noise reduction device comprises a noise reduction chamber arranged between two tracks, a damping pool arranged at the bottom of the noise reduction chamber and a plurality of groups of vibration conduction components arranged between the noise reduction chamber and the damping pool, a first through hole is formed in the top of the noise reduction chamber, the damping pool is filled with damping liquid, a second through hole is formed in the top of the damping pool, the vibration conduction components comprise a plurality of vibration conduction pieces arranged at intervals, the upper ends of the vibration conduction pieces extend into the first through hole, the lower ends of the vibration conduction pieces extend into the damping liquid of the damping pool through a second through hole, air vibration is transmitted to the vibration conduction pieces through the first through hole, and energy dissipation and shock absorption are achieved through the damping liquid after the vibration conduction pieces vibrate. The device can absorb noise in the running process of a subway, so that noise pollution is reduced, and a more comfortable riding environment is brought to passengers.
本发明公开了一种地下交通轨道降噪装置，属于地下轨道交通技术领域，包括设置在两轨道之间的降噪室、设置在所述降噪室底部的阻尼池、设置在所述降噪室和阻尼池之间的若干组振动传导部件，所述降噪室的顶部设置有第一通孔，所述阻尼池内填充有阻尼液，所述阻尼池的顶部设置有第二通孔，所述振动传导部件包括若干并且间隔设置的振动传导片，所述振动传导片的上端延伸至所述第一通孔内，所述振动传导片的下端通过第二通孔延伸至所述阻尼池的阻尼液内，空气振动通过第一通孔传递至振动传导片，振动传导片振动后通过阻尼液消能减震。本发明装置可以将地铁在运行过程中的噪音进行吸收，从而减少噪音污染，给乘客带来更舒适的乘车环境。
