Vehicle accidents are complicated events and the resulting sound sequence created by that event is equally complex. Understanding how accident sounds are created is important for two main reasons. One reason is to better understand the events in an accident sequence that have not left visible physical evidence. There are often witnesses to vehicle accidents, and their observations include what they saw as well as what they heard. This information is useful when reconstructing the accident. Another reason is to be able to create more accurate simulated sound composites of an accident for use in forensic visualization, a visual/auditory tool that helps one understand a dynamic accident sequence that they were not able to see in person. While the composite accident sound is complicated when analyzed as an entire sound sequence it is still derived from discreet parts, and by analyzing the discreet parts individually one is able to better understand the contribution each individual sound makes to the entire accident sound sequence. This paper looks at some of the discreet sounds in a vehicle accident, and evaluates how changes in the parameters of the accident sequence affect the resulting sounds.
