Hotel & Travel Information

This Engineering Academy covers a variety of vehicle noise control engineering principles and practice. Two specialty tracks are available: Vehicle Interior Noise and Powertrain Noise. While the Powertrain Noise track focuses on NVH issues generated by powertrain noise sources and the design strategies to minimize them, the Vehicle Interior Noise track focuses on the understanding and application of acoustical materials to optimize NVH in the passenger or operator compartment of a vehicle. Considerable attention is given to current measurement and instrumentation technologies and their effective use.

Practical Component
This Academy includes several equipment demonstrations and hands-on lab sessions. Specific instrumentation suppliers have been selected for an instrumentation workshop on one evening. There is also a field trip to one of the OEM’s noise and vibration facility in the metro Detroit area. Through these activities, you become acquainted with relevant instrumentation, measurement protocols, and problem solving strategies.
