Exhaust Acoustic and Vibration Testing

Industry: Automotive

Applications: Standardized Testing

A European Tier 1 supplier of exhaust systems needed to characterize the performance of its exhaust system in a US market vehicle. Sound Answers conducted operating acoustic and vibration measurements of the exhaust with the vehicle on the chassis dynamometer in the hemi-anechoic chamber at the Application Research Center in Canton, MI. Multiple microphone locations (interior/exterior), binaural head, and multiple accelerometers along the exhaust systems were utilized to capture the NVH performance of the exhaust system while following the customer’s standard specifications.
