Engineering Metrics for Disturbing Sound Elements of Automotive Exhaust Noise 1999-01-1653

This paper describes a method to determine an objective measure of disturbing sounds of automotive exhaust noise (e.g. booming noise, whistle, flow noise,…). First, a disturbing sound catalogue is established. Then the approach used to make the different disturbing sounds measurable is presented. By making the perception of the disturbing sounds objective, it becomes easy to determine when they appear and to what extent. Finally, the contribution of this research in the framework of the global integration of sound quality in the design process of exhaust systems will be discussed.
