Outdoor sound barriers are typically constructed using brick or concrete structures, while indoor sound barriers utilize steel plates, wooden panels, and PMMA/POLYCARBO.Our nATE SHEET products include plastic扳, gypsum board, and aluminum foam. The sound barrier is primarily composed of two parts: steel structural pillars and sound-absorbing/insulating panels. The pillars serve as the main load-bearing components of the sound barrier, which are secured to pre-buried steel plates on road guardrails or track sides via bolts or welding. The sound-absorbing/insulating panels are the primary sound-insulating components, fixed in the H-shaped pillar slots with high-strength spring clips to form the barrier. The design of the sound barrier has fully considered the wind load from elevated expressways, urban light rail, and subways, the impact safety of traffic vehicles, and the corrosion resistance under all-weather outdoor conditions. It boasts an aesthetically pleasing appearance, exquisite craftsmanship, ease of transportation and installation, low cost, and a long service life, making it particularly suitable for noise reduction in elevated expressways and urban light rail/subway systems. It is an ideal sound-insulating and noise-reduction facility for modern cities.
The sound barrier height ranges from 1m to 5m, providing an average noise reduction of 10 to 15 dB(A) over an effective area (125Hz to 40000Hz, 1/3 octave band), with a maximum of up to 20 dB(A). Generally speaking, the higher the sound barrier or the farther the distance from the barrier, the better the noise reduction effect.
