Fully Enclosed Noise Barrier

Product Introduction

The Fully Enclosed Noise Barrier System is an advanced acoustic solution designed for high-intensity traffic environments where effective and reliable noise control is essential. Featuring a complete enclosure structure, it integrates high-performance sound-absorbing and sound-insulating panels into a unified system, significantly reducing noise leakage and providing stable, long-term acoustic performance.

Compared with conventional open noise barriers, the fully enclosed configuration provides enhanced sound insulation and effectively contains traffic noise, creating a quieter, safer, and more comfortable environment for nearby communities. Its robust structural design ensures reliable performance under complex highway, urban, and transportation conditions, with excellent durability, weather resistance, and structural stability.

LuoFu offers a comprehensive range of noise barrier systems and acoustic accessories, including Metal Perforated Noise Barriers, PMMA Acrylic Noise Barriers, Photovoltaic Noise Barriers, other specialized acoustic systems, and supporting Acoustic Core Systems.

For complete highway infrastructure projects, noise barrier systems can be integrated with Highway Guardrail Systems and other traffic safety products, providing coordinated solutions for noise control, road safety, and traffic management.

Acoustic Performance

The fully‑enclosed noise barrier integrates sound absorption and sound insulation to limit noise leakage within the traffic corridor. The enclosed tunnel‑style structure delivers superior noise reduction compared with conventional upright noise barriers.
Acoustic indicators including sound‑insulation rating and sound‑absorption coefficient can be customized to satisfy specific project requirements.

Structure & Materials

The system features a robust modular structure with acoustic panels and durable connection components, adaptable to different road conditions and project requirements. Panel and structural materials, including perforated metal, PMMA, and composite panels, can be customized with protective finishes for long-term outdoor durability.

Electromagnetic Shielding Noise Barrier

Customized Electromagnetic Shielding

The Fully Enclosed Noise Barrier can be upgraded by integrating electromagnetic‑shielding structures, or alternatively fitted with extra shielding components, to reduce electromagnetic radiation while maintaining effective noise reduction. This optional configuration is available for projects with specific electromagnetic protection requirements.

Advantages of Electromagnetic Shielding Acoustic Barriers

Material Selection
Materials are selected based on magnetic permeability, magnetic saturation, and shielding requirements, with high-permeability nickel alloys and ultra-low carbon steel (ULCS) available for low-frequency magnetic field shielding.

Integrated Acoustic & Electromagnetic Shielding
The system combines sound absorption with electromagnetic shielding for integrated noise control and electromagnetic field protection.

Low-Reluctance Structure
An optimized magnetic flux path creates a low-reluctance magnetic circuit, improving low-frequency magnetic field shielding performance for rail transit and other electromagnetically sensitive areas.

Performance Specifications of Electromagnetic Shielding Noise Barrier

Production Process

Stage 1: Precision Fabricating

We utilize advanced shearing and CNC bending for the production of panel blanks and specialized auxiliary hardware.

Stage 2: Acoustic Perforation

The front facing panels undergo high-speed CNC punching to ensure optimal sound absorption performance.

Stage 3: Panel Structure Forming

Heavy-duty roll forming is applied to the acoustic panel backplates to achieve precise geometry and structural integrity.

Stage 4:
Reinforced Welding

Industrial-grade structural welding integrates the internal skeleton and keel reinforcement for maximum stability.

Stage 5:
Final Assembly

A systematic multi-layer integration process combines the acoustic core materials, facing panels, and backplates.

Stage 6:
Protective Finishing

The entire unit receives an electrostatic powder coating for superior weather resistance and a professional finish.

Stage 7:
Structural Anchoring

Heavy-duty welding is used to secure base plates, hanging brackets, and reinforcement ribs for onsite installation.
