Description
The lab for acoustic scale model technology allows to investigate and measure the noise propagation using models of the traffic structures and the residential structures surrounding them which are as little as a twentieth of the original size. At a scale of, for example, 1:20, areas of 200 x 200 metres can be simulated on a 10 x 10 metres model table. The wave lengths of the noise emitted by the vehicles on the roads are also shortened in accordance with the model scale. The model sound sources must emit the sound in wideband and evenly in all directions. This results in frequencies in the region of 2,000 to 100,000 Hertz.
