Outdoor sound barriers are generally made of bricks or concrete structures, while indoor sound barriers use steel plates, wooden boards, etc, PMMA/POLYCARBONATE SHEET, gypsum board, foam aluminum and other structures. The sound barrier is mainly composed of two parts: steel structure columns and soundproof screen panels. The columns are the main load-bearing components of the sound barrier, which are fixed to the embedded steel plates on the road crash wall or track edge by bolts or welding; The sound absorbing board is the main sound absorbing component, which is fixed in the H-shaped column groove through high-strength spring clips to form a sound barrier. The design of sound barriers has taken into account the wind load of elevated highways, urban light rail, and subways, as well as the impact safety of transportation vehicles and all-weather outdoor anti-corrosion issues. It has a beautiful and elegant appearance, exquisite production, convenient transportation and installation, low cost, and long service life. It is particularly suitable for noise prevention on elevated highways, urban light rails, and subways, and is the most ideal sound insulation and noise reduction facility in modern cities.

The height of the sound barrier is between 1m and 5m, covering an effective area with an average noise reduction of 10-15dB (125Hz-4000Hz, 1/3 octave band), up to 20dB. Generally speaking, the higher or farther away the sound barrier, the better the noise reduction effect.
