Noise Barriers for Railway Tracks

NOISE SCREEN ELEMENT

highly absorbent on one or both sides
aluminium, polyester powder-coated

Airborne sound insulation
DLR = 30 – 35 dB (EN 16272)
DLR = 25 – 31 dB (EN 1793)
Sound absorption
DLα = 12 – 15 dB (EN 16272)
DLαNRD = 11 dB (EN 1793)

Optional earthing sheet to ground the noise screen
elements against the track

TRANSPARENT RAILWAY ELEMENT

reflecting
