Chat with the Experts

Tuesday

Networking Area
Exhibition Hall C
1:30 - 2:30 p.m.

This activity is designed to create an informal and intimate environment between audience and expert for discussion on a topic relevant to the noise and vibration community. Each "expert" should provide a 2 to 3 minute introspective on what they feel is critical items on the subject to be addressed and then facilitate dialogue within a small group environment. The goal is to enhance understanding of items critical to those participating via interactivity. Each attendee is encouraged to pose questions, share ideas and explore practical solutions.

Topic: Structural Acoustics
Abstract: Structural Acoustics, also known as vibroacoustics, is the study of sound radiated by the motion of structures due to air-borne and/or structure-borne forcing functions.

A fascination with the world structural acoustics of light-weight structures from aerospace systems to the musical instruments has defined a 30+ year research career. Evan Davis joined the Catgut Acoustical Society in 1976, and graduated with a B.S. in Mechanical Engineering from Rutgers University in 1977. Developed loudspeakers and amplifiers suitable for in-flight use for an active noise control system flown on a DeHavilland Dash-8 trubo-prop airplane in 1987, earned a Ph.D. in mechanical engineering from the University of Washington with his work on the structural acoustics design of guitar soundboards in 1990. Introduced Statistical Energy Analysis (SEA) as a prediction method to Boeing Commercial Airplanes and trained engineers in its use to support the design of the 787 noise control package. Dr. Davis has been facility member of the Violin Society of America's Oberlin Violin acoustics workshop since 2006 and is currently employed as a Technical Fellow of the Boeing Company directing research in structural acoustics, noise control and sound quality engineering.

Bridging the Gap between Prediction and Measurement (The Great Divide)
Abstract: In many organizations where both Test and CAE co-exist, there is often a technological and cultural "Great Divide" which separates these two communities. This "Chat with the expert" session will explore this issue in a dynamic discussion where all in attendance will have an opportunity to share their perspectives. The discussion will be framed by the author's own viewpoint from several decades of working in both disciplines and will cover the following topics:

• What is the Great Divide? Does it really exist and why?
• Who cares? Does it even really matter?
• Building Bridges: Spanning the Great Divide
• Test-CAE Correlation: Seven Immutable Laws

The chat is likely to be lively and spirited. It will hopefully spawn vigorous debate and, if nothing else, open the eyes of those from both sides of the issue.

Greg worked in the NVH field at Chrysler for 15 years, focusing his efforts on advanced NVH testing methodologies, target setting and NVH CAE. In 1996, he became Supervisor of the NVH Advanced Engineering team where he led the NVH efforts for all new vehicle programs and advanced methods. Special efforts were made into the integration of NVH methods in the product development process. Earlier in his career, he worked for The Defiance Group as an NVH Senior Test Engineer.

He worked at Material Sciences Corporation (MSC) for 7 years as the Global Director of Research & Development, where he led the Application Engineering and Product Development teams in supporting the commercialization of MSC's various acoustical and coated products. Currently, he is Senior Technical Specialist in Vehicle Engineering at Tesla Motors, working to bring the Tesla Model S to market.

Greg has been an SAE member since 1999 and has been involved in organizing the bi-annual Noise and Vibration Conference since 2001, serving as the General Chair for the 2009 conference. He remains active in SAE leadership and is currently serving as the Automotive Chassis Activity Chair.

Noise Control on a Limited Budget
Identifing and solving noise control problems requires as much creativity as it does specialized equipment. Your lab may not have the specialized equipment traditionally used for every problem you must address, but that does not mean it is incapable. What are your current challenges and equipment limitations? Let us discuss creative ways to solve your current problems; it may be less expensive or as complicated as you think. Recognize that "YOU" are the key instrument at your disposal.

Robert Hand has more than 40 years of experience in the measurement and control of noise and vibration. A former research engineer with the Acoustics and Seismics Laboratory at the University of Michigan, Willow Run Laboratories, he has served as the noise and vibration control specialist for the Corporate Laboratories of Clark Equipment Company, and later the general manager of Clark Engineering Services. Mr. Hand founded Redbud Technology Group, a noise and vibration consulting business. He has served as chairman of the SAE Con. Ag. Sound Level Technical Committee and the CIMA Acoustics Committee, and has produced the SAE technical video tutorial, Basic Noise Control, and regularly teaches the SAE noise control seminar. Mr. Hand has lectured at the University of Michigan, University of Wisconsin and Western Michigan University, as well as participated in numerous SAE technical sessions, and has taken graduate studies at the University of Notre Dame and is an active member of the SAE, INCE and ASA. He has a B.S. in electrical engineering from the University of Michigan and an M.A. in management from Nazareth College.

Brake Noise
Dr. Thompson is the author of the new book from SAE, Brake NVH: Testing and Measurement and will be available to talk on this topic. He has 10 years of experience in brake noise and vibration testing and problem resolution.

Brake noise testing is all about replicating operating conditions. This includes vehicle dynamics, temperatures, humidity, speeds, pressures, etc. There are existing standards such as SAE J2521 and SAE J2625 for brake noise measurement as well as other standards to the measurement of parameters related to brake noise.

Whether you are having difficulty applying one of the existing standards or are having difficulties measuring an unusual noise, Dr. Thompson will be pleased to try to provide assistance. He will be available to discuss test protocols, dynamometers, measurement systems, environmental control, simulation of unique operating conditions, or measurement problems. He will be happy to discuss judder noise, moan/groan, or squeal issues.

Dr. Thompson is currently the Chief of the Hearing Loss Prevention Branch of the National Institute for Occupational Safety and Health (NIOSH). He leads a team of scientists and engineers working to eliminate hearing in the nation's mine workers. Before joining NIOSH, Dr. Thompson worked for Bruel & Kjaer North America as the Great Lakes Regional Manager. He has worked in the field of noise and vibration for over 35 years with positions in industry and academia.

Dr. Thompson received his BS and MS in mechanical engineering from Virginia Tech and his Ph D in mechanical engineering from Purdue University. He has over 30 publications in national and international journals. He is a registered professional engineer in Ohio and Michigan. He is an Institute of Noise Control Engineering (INCE) Board Certified Noise Control Engineer. Dr. Thompson has served as the Chairman of the SAE Tire Noise Standards Committee.
