Light efficient sound absorption type metal sound barrier body
The invention relates to the technical field of urban traffic noise control, and discloses a light efficient sound absorption type metal sound barrier body which comprises an outer frame and an aluminum fiberboard sound absorption structural body arranged at the end, away from a screen body back plate, of the outer frame. The cavity is formed between the aluminum fiberboard sound absorption structural body and the screen body back plate. According to the light efficient sound absorption type metal sound barrier body, the screen body frame is made of a high-strength aluminum alloy material, the dead weight of the screen body can be greatly reduced, the bearing pressure of the screen body on a bridge is reduced, the principle of a cavity resonance structure sound absorber is utilized, a 30 mm aluminum fiber board sound absorption structure is designed and embedded in the front portion of the screen body, and the sound absorption effect is good. Noise sound waves enter the sound absorber to cause vibration of the aluminum fiber board, so that sound wave energy is converted into heat energy, the sound waves enter the rear cavity of the screen body for further energy attenuation after traffic noise is reduced, and the effect of absorbing the traffic noise is achieved.
本发明涉及城市交通噪声控制技术领域，公开了一种轻质高效吸声型金属声屏障屏体，其中轻质高效吸声型金属声屏障屏体，包括外部框架，设置于所述外部框架远离屏体背板一端的铝纤维板吸声结构体，以及设置于所述铝纤维板吸声结构体和屏体背板之间形成的空腔。该轻质高效吸声型金属声屏障屏体，通过采用高强铝合金材料作为屏体框架，可大幅降低屏体的自重，减轻其对桥梁的承载压力，利用空腔共振结构吸声体的原理，在屏体前部设计嵌入30mm铝纤维板吸声结构，噪声声波进入吸声体后引起铝纤维板的振动，使其声波能量转化为热能，降低交通噪声后进入屏体后部空腔进行进一步的能量衰减，达到吸收交通噪声的效果。
