Abstract

Scale models can be used for the prediction of traffic noise levels in built-up areas if we use a model where every size, including the wave length of the sound is scaled down by a factor N, or the frequency is scaled up by that same factor. The scale factor used is 1:100, which is mainly set by the dimensions of the anechoic test room. The equipment used allows as to measure up to 180 kHz. The agreement between theory, outdoor measurement and the model was quite good, as can be seen in four given examples.
