Vehicle Noise Control Engineering Academy - Vehicle Interior Noise
|I.D.# ACAD01||Printable Description|
|October 5-9, 2015 (8:00 a.m. - 8:00 p.m. ) - Troy, Michigan|
This Engineering Academy covers a variety of vehicle noise control engineering principles and practices. 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.
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.
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
- The SAE Pre-Academy is a totally optional offering that in no way affects your participation in the SAE Vehicle Noise Control Engineering Academy. Access to the Pre-Academy web site will be available to all registrants on September 21.
- The SAE Pre-Academy consists of 2-1/2 hours of web-based lessons that can be accessed at your convenience. These lessons provide an overview of basic sound and vibration concepts that are the foundation of noise control engineering. It is intended mainly for those new to the field of noise control, while providing a refresher for those more experienced in the field. In addition to the video lessons, a series of self-assessment questions are provided with solutions furnished upon request.

Gabriella Cerrato is President of Sound Answers Inc., an engineering consulting firm in noise and vibration. Gabriella has more than 25 years of experience in measuring, troubleshooting and predicting noise and/or vibration in a variety of different systems and products. At the beginning of her career, she was involved with environmental noise impact measurement and prediction (from air and ground vehicular traffic and from infrastructures). She then joined the Active Noise and Vibration Control group at FIAT, where she was responsible for the design of the acoustic systems for active control in the cabin and in the exhaust of passenger vehicles. This led her to a position in the Consulting group of Structural Dynamics Research Corporation (SDRC, later acquired by MTS Systems Corp) in Detroit, MI, where she worked on the sound quality of various vehicles and automotive subsystems and where she developed sound quality target procedures. At Sound Answers, she has led the engineering team since 2005 through several consulting projects for industry customers and for DoD customers through SBIR (Small Business Innovation Research) projects. Gabriella has authored over 40 papers for conferences and magazines, has chaired sessions at SAE, Inter-Noise and Noise-Con conferences and is a member of several professional organizations (SAE, AIAA, AES, IEEE). Gabriella has a Doctorate in Theoretical Physics from the University of Torino, Italy.
Alan D. Stuart, is an Associate professor emeritus of acoustics at Penn State. For over 25 years, he taught fundamentals of acoustics courses on both the graduate and undergraduate levels, as well as graduate courses on structural acoustics and applied acoustics. He has conducted numerous professional short courses on acoustics and vibrations and noise control engineering. At Penn State, he was the coordinator of the Summer Program in Acoustics and the Distance Education Program in Acoustics and received numerous awards for his contributions to Continuing and Distance Education. He is an active member of SAE, ASA, INCE and ASEE. Dr. Stuart received a BSME from Pratt Institute, an MSEE from New York University, and a Ph.D. in Engineering Acoustics from Penn State.
