Frequently asked questions
Which NoiseBloc system performs best for rail noise?
Premium TGV, with a rail DLR of 28dB to BS EN 16272-2:2023. Board & Batten achieves 24dB.
Why is rail DLR different from road DLR?
Railway noise has a different frequency spectrum from road traffic. BS EN 16272 weights the barrier's measured performance against a rail spectrum, so the same barrier can score differently for rail and road.
