Hollow combined sound absorption unit and sound barrier thereof
The invention relates to a hollow combined sound absorption unit and a sound barrier thereof. According to the hollow combined type sound absorption unit, the sound absorption unit comprises a unit block body, a tenon bell and spigot is formed in the upper face of the unit block body, a concave mortise bell and spigot is formed in the lower face of the unit block body, the tenon bell and spigot and the concave mortise bell and spigot can be matched and inserted together, and a cavity is formed in the unit block body. The cavity resonance sound absorption structure has the advantages that after the sound absorption units are assembled, one or more cavities are formed, the cavity resonance sound absorption structure is formed, high-frequency noise and low-frequency noise can be reduced at the same time, and the sound absorption performance is remarkably improved. Through the assembling mode that the tenon bell and spigot and the concave mortise bell and spigot which can be matched with each other are spliced with the shell, assembling is convenient, and the unit bell and spigot can be assembled into any height according to needs. By changing the structures of the sound absorption units, the sound absorption performance is improved, the self weight is reduced, and meanwhile the good mechanical property of the absorption (separation) plate is guaranteed.
本发明涉及一种空心组合式吸声单元及其声屏障。本发明的空心组合式吸声单元，吸声单元包括单元块体，单元块体的上面设置凸榫承插口，单元块体的下面设置凹卯承插口，凸榫承插口和凹卯承插口能够相互配合承插在一起，单元块体内具有空腔。其有益效果是：吸声单元拼装完成后具有单个或多个空腔，形成空腔共振吸声结构，能够对高低频噪音同时降噪，吸声性能显著提高。通过能够相互配合的凸榫承插口和凹卯承插口与壳体拼接的组装方式，便于组装，根据需要，通过单元体承插口组装成任意高度。通过改变吸声单元结构，提高了吸声性能，减轻了自重，同时保证了吸(隔)板良好的力学性能。
