Creates continuous enclosed noise reduction along high-traffic road sections.
Fully enclosed sound barriers form a continuous cover around high-noise transport corridors to control noise more completely than side panels alone. The enclosure layout helps protect nearby residential, school, hospital, and commercial areas.
They are used on urban expressways, rail transit, viaducts, bridges, and sections where noise control targets are strict. Panel type, enclosure span, support structure, ventilation, lighting, drainage, and maintenance access are considered during design.

Fully Enclosed Sound Barrier consists of steel supports, side acoustic panels, roof enclosure components, connectors, and foundation systems, forming a covered noise-control corridor. The panels and roof work together to block noise transmission along high-noise roads, railways, and sensitive areas.
Fully Enclosed Sound Barrier cuts noise transmission paths with side walls and a roof enclosure. Absorptive panels reduce reflected sound, barrier panels block direct sound, and the roof limits diffraction. The steel frame transfers wind load and self-weight to the foundation for stable long-span performance.
