Prediction of noise maps for rail and road traffic

In collaboration with ACOUSTIC CONTROL we can offer computerized calculations of noise maps for rail and road traffic. ACOUSTIC CONTROL uses CadnaA software program for the prediction and assessment of noise levels in the vicinity of traffic-systems like roads, railways etc. The program features easy input and configuration of 3D terrain including all objects that influence sound emission and propagation, the calculation and documentation of noise levels in accordance with national regulations, and the presentation of the results with noise contour plots and coloured noise maps. It is possible to calculate the noise from intended railways or roads or subject to substantial modifications, and dimension suitable noise control measures

It is also possible to calculate the noise level at the facade of a building (existing or planned) in order to design proper noise protection for indoor environment.
