Motor racing tracks sound emission model: a comparison between prediction software and experimental data in Umbria Motordrome (Italy)

摘要

Most recent commercial acoustic prediction softwares offer a full set of standard models for several kinds of noise sources, such as roads, railways, aircrafts and industries, but no motor racing track models are implemented. The aim of the present paper is to create a motor racing tracks-dedicated model, which could be applied to both cars and motorcycles without any restriction in number or categories, by using one of the commercial sound prediction software. The model is realized by means of experimental data measured at the Umbria Motordrome (Italy).
