Toolbox from the EC FP7 HOSANNA project for the reduction of road and rail traffic noise in the outdoor environment
Paper in proceeding, 2014
This paper offers a brief overview of innovative methods for road and rail traffic noise reduction between source
and receiver. These include using new barrier designs, planting of trees, treatments of ground and road surfaces
and greening of building façades and roofs using natural materials, like vegetation, soil and other substrates in
combination with recycled materials and artificial elements. The abatements are assessed in terms of numerically
predicted sound level reductions, perceptual effects and cost–benefit analysis. Useful reductions of noise from
urban roads and tramways are predicted for 1-m-high urban noise barriers and these are increased by adding
inter-lane barriers. A 3 m wide 0.3 m high lattice ground treatment, a carefully planted 15-m-wide tree belt and
replacing 50 m of paved areas by grassland are predicted to give similar reductions. Tree belts are shown to be
very cost-effective and combining tall barriers with a row of trees reduces the negative impact of wind. Green
roofs may significantly reduce the noise at the quiet side of buildings.
