Abstract:
Source-Path-Contribution (also known as transfer path analysis or noise path analysis) comprise a well-known set of techniques that have traditionally been performed in the frequency domain. With advancements and modern techniques, these same principles can be applied accurately in the time-domain. Foremost among the benefits of this are an ability to analyze transient events, and the ability to listen to the contributions from various sources instead of merely viewing them. This paper demonstrates the analysis of a diesel engine vehicle utilizing time-domain source-path-contribution techniques.
