Composite sound absorption barrier
The invention discloses a composite sound absorption barrier which comprises a sound insulation module and a sound absorption module fixed to one side of the sound insulation module. The sound absorption module is formed by connecting a plurality of sound absorption units in the longitudinal direction, each sound absorption unit comprises a frame and a sound absorption body, each frame comprises an upper frame body, a lower frame body and side frame bodies, frame cavities defined by the upper frame bodies, the lower frame bodies and the side frame bodies are filled with the sound absorption bodies, the upper frame bodies are provided with first splicing structures, the lower frame bodies are provided with second splicing structures, and the second splicing structures and the first splicing structures correspond and carry out locating in cooperation. According to the composite sound absorption barrier, a split structure is adopted in the sound absorption module, the frames can be longitudinally spliced through the splicing structures of the longitudinal adjacent frames, mounting, dismounting and transporting are facilitated, sound absorption height can be adjusted according to needs, and high universality is achieved. Besides, the adjacent frames can be spliced in place at a time through the first splicing structures and the second splicing structures, mounting efficiency is improved, the spliced sound absorption units can be closely attached, and the sound absorption effect is improved.
