Noise Modelling
CadnaA is a computer noise modelling programme which we use to predict the noise impact that a development such as industrial facilities, transport networks, windfarms and items of noise generating plant and machinery may have on the ambient noise climate of a given area or at a particular receptor. The modelling software predicts noise levels in accordance with International Standards such as ISO 9613-2, 1996 Acoustics-Attenuation of sound propagation outdoors.
