Vehicle Noise Control Engineering Academy - Vehicle Interior 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): Vehicle Interior Noise and Powertrain Noise. Participants should choose and register for the appropriate track they wish to attend.

The Vehicle Interior Noise track focuses on understanding the characteristics of noise produced by different propulsion systems, including internal combustion, hybrid and electric powered vehicles and how these noises affect the sound quality of a vehicle’s interior.  The vehicle in this case includes passenger cars, SUVs, light trucks, off-highway vehicles, and heavy trucks. The Vehicle Interior track presents relevant numerical analysis techniques and sound package (acoustical) materials that can be used to optimize the vehicle interior acoustics characteristics.  Considerable attention is given to how acoustical materials work and to current measurement and instrumentation technologies and their effective use.  

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 an OEM or supplier noise and vibration facility in the metro Detroit area. Through these activities, you become acquainted with relevant acoustic test facilities, 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
  • Articulate the differences in various numerical techniques that are used for simulation
  • Discuss the importance of sound quality issues for EV and ICE propulsion units in developing a quality vehicle
  • Identify available acoustical materials and determine their optimum application
  • Recognize new materials that are used in sound package applications
  • 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 interior 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.
