construction site noise barrier

Product Specifications

When the sound wave propagating in the air meets the soundproofing noise barrier, it will produce reflection, transmission and diffraction. Some of them diffracted across the top of the soundproofing noise barrier to the sound receiving point, some of them penetrated the soundproofing noise barrier to the sound receiving point, and some of them reflected on the wall of the sound barrier. The insertion loss of the soundproofing noise barrier mainly depends on the sound energy distribution of the sound wave generated by the sound source traveling along the three roads. The function of the soundproofing noise barrier is to block the propagation of direct sound, isolate the transmitted sound, and make the diffracted sound have enough attenuation. When sound waves hit the wall of the sound barrier, diffraction will occur at the edge of the sound barrier, and a "sound shadow area" will be formed behind the sound barrier. The noise reduction effect of the noise barrier we expect is in the "sound shadow area"

The middle of the sound barrier is glass wool. It has many advantages, such as flame retardant, non-toxic, corrosion resistant, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption, good hydrophobicity, etc. It is recognized as the most superior thermal insulation, heat insulation, sound absorption material, and has a very wide range of uses. The boards, felt and pipes made of this material have been widely used in the fields of construction, chemistry, electronics, electricity, metallurgy, energy, transportation and other fields for heat insulation, sound absorption and noise reduction, with remarkable effects. Because of its soft texture, fine fiber and low slag ball content, this material will not irritate the skin during construction, so it is welcomed by the construction unit and becomes the preferred product for thermal insulation
