The invention discloses a noise reduction device placed on a trapezoidal sleeper ballast bed in the field of rail transit. The device comprises a trapezoidal sleeper arranged on the ballast bed, and the trapezoidal sleeper is fixedly connected with a steel rail arranged on the trapezoidal sleeper through a fastener; noise reduction units are arranged on the trapezoidal sleeper, and gaps exist at the joints of the steel rails; the noise reduction unit is located at a gap between two connected steel rails; and the noise reduction unit comprises a sound insulation plate fixedly arranged on the trapezoidal sleeper. The influence of noise generated by a train on the surrounding environment can be reduced, and low pressure generated when the train passes can be used for blowing air to the gaps, so that the situation that sundries are embedded into the gaps, the connecting positions of steel rails are uneven, noise generated when the train passes is increased, and the environment is influenced is avoided.
本发明公开了轨道交通领域的一种放置于梯形轨枕道床上的降噪装置，包括设置在道床上的梯形枕轨，所述梯形枕轨通过扣件与设置在梯形枕轨上的钢轨固定连接；所述梯形枕轨上设置有降噪单元，所述钢轨与钢轨的连接处存有缝隙；所述降噪单元位于两相连接钢轨的缝隙处；所述降噪单元包括固定设置在梯形枕轨上的隔音板。本发明不仅能够降低列车发出的噪音对周围环境的影响，还能够利用列车经过时产生的低压，对缝隙处进行吹风，避免缝隙内嵌入杂物，使得钢轨与钢轨的连接处不平整，使得列车经过时产生的噪音增大，影响环境。
