Definitions

  • the invention relates to an acoustic display module; comprising a first perforated sheet, suitable for forming a side exposed to a noise source; and a second plate suitable for forming a side protected from said noise; said plates define two main surfaces, freckled or smooth, and comprise at two opposite ends mutual coupling means; delimiting both plates an inner cavity suitable for the placement of a noise absorbing material.

  • Anti-noise screens are also called acoustic screens or barriers, and their function is to prevent the transmission of noise from one side of their physical space to the other. These screens are installed close to the communication routes that have high levels of noise, such as roads, railways, airports, and are an effective means to reduce or eliminate this noise from this source emitting the area to be preserved. , effectively reducing in this protected area the harmful and annoying effects of noise.
  • the screen behaves like an enclosure that acts as an obstacle to the transmission of noise between the emitting bulb and the area to be protected, which is an area with population; the acoustic insulating screen is used in front of fixed noise or traffic sources when sound waves are absorbed by the screen.

  • a first objective of this acoustic screen module is that it presents constructive characteristics oriented to allow a compact stacking of the forming sheets of the modules, where the pressure suffered by the sheets in the stack is uniform throughout its surface, reducing the space and the costs derived from its storage and transport, without risks of the sheets becoming deformed in this position. In turn, these characteristics allow to reduce the manufacturing costs of the sheets.
  • Another objective of the invention is to provide the plates with a configuration that facilitates the assembly and, not least, the disassembly of the module for subsequent recycling, in a quick, simple, safe and without the intervention of external elements of fixing or subsequent additional folding work once the plates are assembled.

  • the screen created with the modules object of the invention is also characterized by the mechanical resistance to bending that it offers against the pressure of the wind, which prevents plastifications of the sheets from being produced by presenting a form of continuous connection between them, without joining areas by means of fasteners that can be deformed by this pressure.
