Final report of QUIESST WP 2 – Extrapolation of near field Reflection Index data to far field reflection performance indicators
report
Sound reflectivity is one of the intrinsic acoustical characteristics of noise barriers. It describes which percentage of an incident sound field is reflected back towards the opposite side of the road. The reflectivity is determined by the absorption properties of the material of the barrier as well as by the geometrical shape of the barrier, which may enhance or diminish sound reflections in certain directions. The reflectivity effect in the far field is thus not only related to the barrier and its design, but also to the receiving position in the far field.
