Augmenting Vehicle Production Audit with Objective Data and Sound Quality Metrics to Improve Customer Satisfaction 2019-01-1531

Vehicle manufacturers are facing increasing challenges in auditing the build quality of their vehicles while considering increasing consumer demands. This effect is compounded with the rise in electric and hybrid vehicles. The ability to audit vehicles at the end of line for a variety of noise types is becoming increasingly important; these include engine noise, road noise, wind noise, BSR and electric vehicle specific noises. An automated measurement system was developed with specific algorithms and sound quality metrics to not only audit vehicle production but to add objective data, pass-fail criteria and trend analysis.
