Vehicle Noise Control Engineering Academy - Powertrain Noise Track



The Vehicle Noise Control Engineering Academy covers a variety of vehicle noise control engineering principles and practices. There are two concurrent, specialty tracks (with some common sessions): Powertrain Noise and Vehicle Interior Noise. Participants should choose and register for the appropriate Academy they wish to attend.

The Powertrain Noise track focuses on noise and vibration control issues associated with internal combustion, hybrid and electric powered vehicles. The vehicle in this case includes passenger cars, SUVs, light trucks, off-highway vehicles, and heavy trucks. 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.

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 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 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 depending on current COVID-19 limitations.

Learning Objectives
By attending this Academy, you will be able to:
  • Define vehicle acoustics engineering terminology and principles
  • Identify different noise elements in electric vehicles from IC engine vehicles and the uniqueness of the EV propulsion system
  • Discuss the importance of sound quality issues for EV and ICE propulsion units in developing a quality vehicle
  • Articulate powertrain noise terminology and principles
  • Formulate a systematic approach to problem solving and measurement
  • Conduct appropriate performance verification tests
  • Analyze the contributing vehicle noise sources when devising noise solutions
  • Produce valid measurements with noise instrumentation and accurately interpret results
Who Should Attend
This academy will be especially valuable for engineers and technical staff who address powertrain noise in the following types of vehicles: passenger cars and autonomous vehicles, light trucks, heavy trucks, off-highway vehicles, farm machinery, small planes, personal watercraft, and rail transit vehicles.
