Abstract:
A comparatively simple six-parameter model has been developed which fits quite well the underlying power spectra of most vehicular traffic noise samples which we have examined. The six free parameters of the model define a system which can easily be represented in either electronic or digital form. In such a form the system can then be used to generate a time series which has the same underlying, or average, power spectrum as the traffic noise which it represents. It does not however incorporate the characteristics noises of motorcycles, trucks, buses, etc. The model can be used as a laboratory tool for identifying the annoying characteristics of traffic noise or for evaluating proposed automobile and truck noise standards. As such it is much more flexible than current methods which use actual traffic noise recordings. It may also be possible to extract from the parameters of the model a more sensitive measure of traffic noise annoyance than is now available. The techniques used in fitting the model to the power spectrum are applicable not only to traffic noise but may be applied in many other areas as well.
