Summary:

An investigation of the disturbing sound elements of automotive exhaust noise will be discussed (e.g. whistle, raspy, boom). The investigation is performed in three steps. First a sound catalogue is established with a definition for each disturbing element. Subsequently, for each of these disturbing elements a metric is determined. This paper is focused on the final step, which consists in determining the link between each metric and the construction of the exhaust system. The case of a whistle generated by a perforated tube will be discussed. Another element that will be discussed is putter, which occurs and the end of the coast-down, before the transition to idle rpm
