Module noise-absorbing panels for soundproofing screen

摘要

The invention relates to the field of road construction, in particular the creation of noise protection structures to protect residential areas near highways, trails and tracks of industrial facilities. The technical result is improvement in anti-noise properties. Summary of the utility model is that the sound-absorbing panel module includes a housing with front and rear walls, inside which is placed a filler for absorbing energy of sound waves. The front wall turned towards the roadway and its sound trap formed as recesses: pockets or troughs whose dimensions are selected to be absorbed by the sound wave length. When this pocket is formed by a reflective wall opposite the latter side wall of the shelf and connecting the free edges of the reflective wall to the front wall. The shelf made window cavity pocket connecting with the interior of the housing and the sound trap immersed in a sound absorbing filler completely filling the module housing. The longitudinal side walls of the module are provided with tongue and groove elements. 12 ZP f ly-4-yl.
