High-speed railway noise barrier is a special vibration-resistant acoustic facility designed exclusively for high-speed trains running over 200km/h. Different from ordinary highway barriers, it targets composite noise including wheel-track impact noise, aerodynamic noise and engine roar generated by high-speed rolling stock.
It adopts modular combined structure: micro-perforated metal sound-absorbing panels at lower section + transparent PC/PMMA panels at upper section, matched with heavy-duty anti-vibration H steel posts. It meets TB/T 3122 railway industry standards, featuring strong vibration fatigue resistance, wind pressure resistance and long-term anti-corrosion. Widely applied on ground railway lines, elevated viaducts, intercity railways and suburban high-speed rails adjacent to residential blocks, schools and hospitals.

Product Structure & Composition
The complete set consists of anti-vibration H-beam main posts, metal sound absorption panels, transparent sound insulation panels, elastic damping rubber gaskets, waterproof sealing strips and full sets of anti-loose fixing hardware.
Lower Metal Sound Absorbing Panel
Front micro-perforated galvanized steel / aluminum plate, back solid backing plate; inner filled with hydrophobic fireproof glass wool (hydrophobic rate ≥98% per TB/T 3122 standard). Optimized perforation layout absorbs medium & high frequency train noise efficiently, NRC≥0.85.
Upper Transparent Sound Insulation Panel
High-impact polycarbonate / acrylic sheet, light transmittance ≥90%, anti-UV, anti-yellowing, excellent bending strength. Avoids dark tunnel effect, guarantees driver sightline and urban landscape permeability.
Anti-Vibration Support System
Heavy hot-dip galvanized H steel columns with thickened wall, added vibration damping base pads to offset long-period vibration from passing high-speed trains; all bolts use anti-loose locking design to prevent loosening under frequent train vibration.
Core Product Advantages
✅ Professional Anti-Vibration & Fatigue Resistance
Specially optimized for frequent vibration impact of high-speed rail; passed long-term vibration fatigue test, no panel loosening, no weld cracking after years of train operation, fully compliant with TB 10505 engineering design specification.
✅ Targeted Efficient Noise Reduction
Aims at multi-frequency noise of HSR; overall sound insulation RW≥30dB, maximum insertion loss up to 38dB, effectively cut aerodynamic and wheel-track noise by 25–40dB, protecting nearby sensitive areas.
✅ High Weather & Corrosion Resistance
Whole system hot-dip galvanized + polyester powder coating; fluorocarbon coating optional for coastal salt fog zones, anti-rust, anti-UV, frost-proof and rainproof, service life up to 20–30 years.
✅ High Structural Stability for Rail Load
Wind load, snow load and vibration load calculated per railway standard; thickened steel frame resists strong crosswind along open rail corridors, no tilt or deformation.
✅ Modular Fast On-Site Installation
Standard prefabricated panels, lightweight easy lifting; compatible with short railway construction window periods, reduce occupation time of rail tracks and lower labor cost.
✅ Low Maintenance & Long Service Life
Internal sound-absorbing cotton fully hydrophobic, no water accumulation inside panels; smooth surface easy to clean, anti-graffiti coating optional, few replacement parts needed in whole lifecycle.
✅ Fully Customized Matching Rail Projects
Adjustable panel height ratio, total barrier height, span, RAL color and curved top design; support drawing customization for ground track, viaduct and fully enclosed HSR tunnel schemes.

FAQ
Q1: What makes HSR noise barriers different from highway sound barriers?
A: High-speed trains generate continuous strong vibration and composite aerodynamic noise. Our HSR barriers adopt thickened anti-vibration steel frame, elastic damping pads and anti-loose fasteners to avoid loosening under long-term vibration, fully complying with special railway vibration fatigue standards, while highway barriers do not meet such vibration resistance requirements.
Q2: Can it be used for fully enclosed high-speed rail tunnel noise reduction?
A: Yes. We supply matched full-enclosure arched top panels, integral rigid steel frame and drainage lightning protection system, customized full closed noise barrier tunnel for urban core HSR viaducts with severe noise pollution.
Q3: How long can transparent panels serve on high-speed rail lines?
A: Imported high weather-resistant PC/PMMA sheets pass 1000h UV aging test, anti-yellowing and anti-impact, service life 15–20 years; fluorocarbon metal panels can reach 30 years service life in coastal areas.
Q4: Does the product pass railway standard inspection for bidding projects?
A: All products are produced strictly per TB/T 3122 railway standard, with complete factory test reports, salt spray test reports and CE certificates, fully meeting international and domestic railway tender document requirements.
