Vehicle Noise Control Engineering Academy
ACAD15
- Content
The Vehicle Noise Control Engineering Academy covers comprehensive vehicle noise control engineering principles and practices. There are a total of seven topics covering powertrain noise and interior noise associated with internal combustion, hybrid and electric powered vehicles. The vehicle in this case includes passenger cars, SUVs, light trucks, off-highway vehicles, heavy trucks, and many other ground vehicles.
The Powertrain Noise focuses on noise and vibration control issues. Sources and controls addressed include those related to gasoline, diesel, and electromagnetic engines, transmissions/transfer cases, accessories, exhaust, mounts, dampers, gears, axles, joints, and couplings. Considerable attention, with in-class demonstrations, is given to current measurement and instrumentation technologies that are available to identify and analyze vehicle noise sources.
Interior Noise focuses on understanding the characteristics of noise produced by different propulsion systems, the uniqueness of these noises, and how these noises affect the sound quality of a vehicle’s interior. Three different types of sound package materials that are widely used to optimize the vehicle interior acoustic characteristics are discussed here. Considerable attention is given to how acoustical materials work, including their similarities and differences and to current measurement methodologies to evaluate their performances.
The academy builds the bridge, using subjective response, simulation, and instrumentation technologies, between the source and the receiver in the vehicle. It presents relevant discussions on sound quality, numerical analysis techniques, and signal processing methods and techniques.
As part of this academy, you will receive the book, Acoustical Materials: Solving the Challenge of Vehicle Noise, by Pranab Saha.
Practical Component
This academy includes workshops on sound quality and on numerical methods. In addition, specific instrumentation suppliers have been selected for an instrumentation workshop on one evening. There is also a field trip to one of the OEM or supplier noise and vibration facilities in the metro Detroit area. Through these activities, you become acquainted with relevant instrumentation, measurement protocols, and problem-solving strategies.Note: the actual OEM or supplier location may vary.
Day 5 ends at 5:00 p.m.
