The slope  descriptor aims to describe effects of noise that are not dealt with by classical energy descriptors currently used in normative and legislation. This descriptor is in  state of development and currently there is important empirical support that relates it to the  subjective parameters such as quietness and noisiness. In this article a model for the  controlled combination of sound events is used to search the relation between the  traffic parameters such as flow and percentage of heavy vehicles with the  above descriptor. The results may be important for city planning tasks and the  method could be applied to research the response of diverse descriptors related to diverse kind of sounds and parameters
