Printable Description

Duration: 5 Days
Upcoming open enrollment dates being scheduled. Please check back.

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 to furnish equipment and assist with the sessions. Through these activities, you become acquainted with relevant instrumentation, measurement protocols, and problem solving strategies. Also, an in-class case problem is utilized throughout the Academy to tie theory and concepts to practical application.

During the Academy, you will be assigned to a project team and a case problem will be distributed. Each team prepares a response to the case, which requires newly learned concepts to be applied. At the conclusion of the Academy, each team presents their case response to instructors who provide feedback and discussion.

Pre-Academy Activity
Prior to the week-long Academy, there are important pre-work assignments which may include readings and exercises for self study on noise and vibration introductory concepts, sensors, and decibels. In addition, a Webex-telephone conference call is scheduled to review fundamentals and answer questions.

Learning Objectives
By attending this Academy, you will be able to:

• Define vehicle acoustics engineering terminology and principles
• Identify available acoustical materials and determine their optimum application
• 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 who address interior noise in the following types of vehicles:

• Passenger cars
• Light trucks
• Heavy trucks
• Off-highway vehicles
• Farm machinery
• Small planes
• Personal watercraft
• Rail transit vehicles
