Device designed to obtain a reduction of the sound wave diffraction effect, to be installed at the top of anti-noise barriers or other structures. An inherent property of waves, and of sound waves in particular, is their ability to travel around obstacles, scientifically known as diffraction. The noise reducer is installed at the top of anti-noise barriers or other structures to limit this phenomenon. Thanks to its special sound-absorbing properties, it allows the user to raise the virtual height of the anti-noise barrier. Obvious advantages in terms of environmental impact and costs. The device features the following construction characteristics: Outer element Consists of folded (aluminium or steel) sheeting, painted or pre-painted and drilled to form a polygonal section. Inner element Consists of a helical galvanized steel pipe. Sound-absorbing material Sandwiched between the inner and outer elements; it consists of mineral wool with a doughnut-like cross-section. Joint covers Polygon-shaped, these are used to join and couple the various elements of the noise reducer and the end "plugs (also polygonal). Support structure Suitable for attachment to the underlying structure.
