Absorptive noise barrier
- Noise barriers systems manufactured and supplied by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are in compliance with standards: TCCS 45:2022/TCĐBVN, TCVN 11823:2017, BS EN 1794:2003, TB/T 3122-2019, TB 10505-2019,… meeting stringent requirements for technical specifications, manufacturing processes, and production equipment.
- Noise barrier systems are designed to reduce the propagation of noise from the source to surrounding environment, particularly residential communities, schools, hospitals, and other noise-sensitive facilities, while also enhancing the visual appearance of the infrastructure. In addition, noise barrier systems can provide wind shielding, improve driver concentration, and contribute to greater safety for road users and vehicles.
- The products are manufactured under internationally certified management systems, including ISO 9001:2015 Quality Management System, ISO 14001:2015 Environmental Management System, and ISO 3834-2 Welding Quality Management System.
Product Features
- The absorptive noise barrier system consists of steel posts, safety cables, absorptive noise panels, and installation accessories.
- The posts are fabricated from H-shaped steel sections.The post bases are welded to base plates and reinforced with stiffeners to ensure adequate structural strength and load-carrying capacity.
- Absorptive noise panels are constructed using high-performance acoustic materials such as Rockwool, Polyester… enclosed within aluminum alloy or galvanized steel frames. The front plate is designed with perforated sheets or louvered openings to absorb airborne noise and prevent sound waves from being reflected back toward the noise source
- The products are designed to meet acoustic performance criteria in accordance with TCCS 45:2022/TCĐBVN, EN ISO 11654, KS F4770, TB/T 3122-2019…. The absorptive noise barrier achieves a sound absorption coefficient (αw) of 0.9 or higher, corresponding to Class A sound absorption performance in accordance with EN ISO 11654.
