Rail Transit Noise Barrier Metro & Light Rail Acoustic Panel
Rail transit acoustic barrier for metro and light rail systems, engineered for low-frequency train noise attenuation. Withstands aerodynamic pressure pulses from passing trains. Compliant with railway-specific acoustic standards.
Rail transit noise barriers are specialized acoustic structures designed for the unique noise characteristics of rail transportation. Unlike highway barriers, rail barriers must handle wheel-rail interaction noise (especially on curves), braking squeal, engine/motor noise, and the air-pulse effect of high-speed trains in tunnels.
Rail noise differs from road traffic noise:
