✦ Synopsis

Traffic noise recordings have been analysed and presented in the form of graphs of the percentage of time during which the noise remains between certain levels against the levels involved. It has been established experimentally that observations presented in this form approach a Gaussian distribution. To account for this Gaussian distribution a statistical model of traffic noise has been evolved and used with reasonable success as a prediction mechanism to evaluate another random noise situation similar to that of traffic noise. The model also enables experimental data relating to noise surveys to be characterized by a limited number of parameters capable of describing a particular random noise situation in a physically meaningful manner. The article includes an account of the various practical techniques used in the statistical analysis of traffic noise and a discussion of the extent to which the theoretical model is verified experimentally.
