What is the structure of the sound barrier?
Sound barrier height between 1m and 5m, covering the effective area of ??the average noise reduction of 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1/3 octave), up to 20dB (A). In general, the higher the sound barrier, or the farther away from the sound barrier, the better the noise reduction effect.
The board is the main sound insulation component, which through the high-strength spring clip to be fixed in the H-shaped column groove, the formation of sound barrier. Sound barrier design has been more fully considered the elevated highways, urban light rail, subway wind load, traffic vehicle impact safety and all-weather open air corrosion problems. It is beautiful, beautiful, easy to install, low cost, long service life, especially for high-speed highway and urban light rail, the use of subway noise, is the ideal modern city noise noise reduction facilities.
The sound barrier is mainly composed of steel structure column and suction sound screen board. The column is the main force component of the sound barrier. It is fixed by bolts or welding on the buried steel wall of the road anti-collision wall or track;
Outdoor sound barrier is generally made of brick or concrete structure, indoor sound barrier reference steel plate, wood board, PMMA / POLYCARBONATE SHEET plastic plate, gypsum board and foam aluminum and other structures.
