Acoustic barriers - Import export

Our on-site engineering department at Nole designs industrial soundproofing systemswhich are then manufactured and installed by our specialized staff, according to the needs of the customer who is dealing with the problem of noise pollution. We design and manufacture: Sound-proof booths and sound-absorbing cabins for machinery and production lines. Sound isolation booths for line operators Soundproofed cabins for engine test benches Soundproofed walls Fixed and mobile acoustic screens for industry Acoustic panels and barriers. Air treatment within soundproof booths or cabins For a number of years now, our company has, in addition, been offering the market its experience in the manufacture of protections and repair mechanisms for industrial machines, equipment and production lines.

with expanded clay or with mineral wood fibres The factors that mostly affect the efficiency of acoustic barriers are sound-insulation linked to the masses involved and sound-absorption linked to the porosity and shape of the materials. The noise barrier consists of two layers, one of normal reinforced concrete with a density of 2200-2400 kg/mc, having a supporting function, one of light porous concrete with a density of 900-1100kg/mc. FIP and TECNOACUSTICA offer a noise barrier consisting of a 100mm-thick prefabricated structure of self-stable reinforced concrete and a Greek-fretted facade made of lightweight concrete panels with expanded clay and/or mineral wood fibres for a total thickness of 120mm.
The standard length of panels is 292 cm, which permits a typical centre distance of 3 metres. In terms of height, standard measurements of individual panels are 1.5 metres and 2 metres. Panels are fitted onto metal frames that are dimensioned so as to withstand the stress resulting fro

The noise reducer is a barrier devices that enhances the performances by virtue of sound wave propagation at the point of "diffraction". With the installation of the noise reducer it is possible, the acoustic result being equal, to reduce the barrier height thus obtaining a benefit in terms of visual impact. The elliptical noise reducer, thanks to its special geometrical configuration, can be installed on any type of barrier, reducing the sound pressure field behind the screen. The installation of the elliptical noise reducer guarantees an increase in the Insertion Loss value ranging between 1.7 and 4.4 dB(A) depending on the chosen reception in the barrier acoustic shadow area, and the testing method, the height being equal or adding the reducer, as certified by free field testing, in compliance with standard ISO 10847. The elliptical noise reducer consists of a shell of aluminium sheet, or hot-galvanized painted perforated sheet with circular holes with six different diameters, to o
