Abstract
Typically pass-by noise evaluation is performed very late in the vehicle development cycle and any changes or modifications are costly, making an exterior modeling procedure compatible with both test and math-based techniques desirable. This paper demonstrates how the Airborne Source Quantification (ASQ) technique can be applied to modeling vehicle exterior noise. The results of this study also show that the source strength of individual sub-systems, i.e. the engine or transmission, can be determined independently from the full vehicle using a sub-system dynamometer. Results are correlated by assessing source strength and overall pass-by sound pressure level.
