Description

technical field

[0001] The invention relates to the fields of noise control and vibration control, and belongs to a sound absorption, sound insulation and vibration reduction device, in particular to a barrier for absorbing and isolating noise on both sides of a road and a railway. Background technique

[0002] Various vehicles will generate strong noise when running on roads or railways. In order to reduce the impact of noise on production facilities, buildings and people's lives, suction absorbers are usually installed next to roads or railways that pass through bridges, residential areas or industrial areas. Sound insulation barrier to achieve sound insulation and noise reduction. With the acceleration of people's life rhythm, the speed of motor vehicles is getting higher and higher. Many passenger rail vehicles have been speeded up to 200-250 km / h, and will even be speeded up to 300-350 km / h in the future. However, the suction partition currently used Due to the functio...
