Noise Barrier Panels Reduce The Sound Energy, So As To Improve The Sound Insulation Effect

With the transportation, industry production, urban construction of the rapid development of environmental noise pollution is increasingly serious, and Noise Barrier Panels is to ease the noise pollution ー an important facility. At present, most of the Noise Barrier Panelss are composed of panels, back plates, side panels, and sound-absorbing panels arranged in the shells in which they are formed. The improvement of the Noise Barrier Panels for the prior art is mainly carried out from the panel surface and the sound absorbing board material. At present, the Noise Barrier Panels panels are mainly blinds and perforated two kinds of species. Blinds are the most common structure, but the sound insulation is also the most undesirable. While the perforation type although the sound insulation effect has improved. But most of the open are round holes, and the shortcomings of the hole is the unit area within the hollow area is small, thus affecting the sound insulation effect. The improvement of the surface of the Noise Barrier Panels panel is mainly in the panel surface to set the groove or ribs, thereby increasing the surface area of the panel, thereby increasing the sound and the impact of the panel area, making the sound insulation has improved. But the set of grooves or ribs are arranged in parallel, the parallel set of shortcomings in the dry sound waves interfere with each other is limited, thus affecting the sound insulation effect.

The new purpose is to solve the above problems, providing a Noise Barrier Panels panel for improving the Noise Barrier Panels sound effects. The technical proposal for realizing the utility model is a Noise Barrier Panels panel comprising a mounting part and a sound insulation part, and the sound insulation part has a plurality of flower holes. The muffler is also provided with a maze-shaped rib or a maze-shaped groove. The utility model has a positive effect (I) The surface of the Noise Barrier Panels panel of the utility model has a plurality of flower-shaped holes, and the hollow area per unit area of the flower-shaped hole is 23 times that of the circular hole, which greatly increases the penetration of the noise Area, reducing the noise reflection, and thus greatly improve the sound insulation effect, and flower-shaped hole also improved the Noise Barrier Panels of ornamental. (2) The surface of the Noise Barrier Panels panel of the utility model is provided with a maze-shaped rib or groove, which not only increases the impact area of the sound wave and the panel, but also increases the energy loss of the sound wave, Angle changes, and change the rules, so that the sound waves interfere with each other, reduce the acoustic energy, thereby further improving the sound insulation effect.
