Noise reduction and sound absorption device beside subway rail
The invention discloses a subway rail-side noise reduction and sound absorption device, and relates to the technical field of noise control, the subway rail-side noise reduction and sound absorption device comprises a noise reduction unit and two connecting covers, the two connecting covers are detachably connected to the upper end and the lower end of the noise reduction unit respectively, the noise reduction unit is used for being vertically arranged on the outer side of a subway wheel rail, and the noise reduction unit comprises multiple noise reduction layers arranged side by side; the adjacent noise reduction layers are attached to each other, the adjacent noise reduction layers are connected by detachably connecting the ends of the noise reduction layers into the connecting cover, and the noise reduction unit can suppress full-band noise. According to the invention, low-cost, high-efficiency and high-pertinence noise reduction and sound absorption of wheel track noise can be realized.
本发明公开了一种地铁轨旁降噪吸声装置，涉及噪声控制技术领域，包括降噪单元和两个连接盖，两个连接盖分别能够拆卸地连接于降噪单元的上下两端，且降噪单元用于垂直布设于地铁轮轨的外侧，降噪单元包括并排设置的多层降噪层，相邻的降噪层之间相互贴合，通过将各降噪层的端部能够拆卸地连接于连接盖内，实现相邻的降噪层的连接，降噪单元能够对全频段噪声进行抑制。本发明能够实现实现对轮轨噪声的低成本、高效率、高针对性的降噪吸声。
