Dr. Thompson received his BS and MS in mechanical engineering from Virginia Tech and his PhD 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. He also served as the Chairman of the Experimental Methods Technical Subcommittee of the Institute of Noise Control Engineering, from 1991 to 2004. He has served on two ISO working groups ISO/TC 31/WG 3 Tyres - Test Methods of Measuring Tyre/Road Noise Emissions and ISO/TC 43/SC 1/WG 27 - Vehicle Noise Testing: Tyre Selection and Temperature Effects. He won the Superior Paper Award 1994 Tire Society Conference for paper entitled "Plane Wave Resonance in the Tire Air Cavity as a Vehicle Interior Noise Source". In 1998 he received the SAE Forest R. McFarland Award for contributions to session and organizational efforts for the SAE Noise and Vibration Conference. In 2006 he was elected to SAE Fellow grade. He received the SAE Lloyd L. Withrow Distinguished Speaker Award in 2009.

Dr. Thompson currently serves as President of the Institute of Noise Control Engineering. He also is the General Chair of the SAE 2011 Noise & Vibration Conference.

Automotive Noise Control: Thirty Years of Changing Perspectives

This presentation will discuss the changes in the perceptions of noise control and how it is applied in the automotive industry over the past 30 years. The author's point of view is that noise control is a lifetime profession with constant opportunities to learn, grow, and stretch beyond one's comfort zone. Many of the examples cited in this discussion will be from the presenter's in depth experience with tire -pavement and brake noise control. The objective of the presentation will be to illustrate the changes in perspective, and how these changes have led to different directions in the practice of noise control. The evolution from making each component as quiet as possible to considering the entire vehicle system to considering the character, rather than just the magnitude, of noise will be described with examples. To illustrate these historical changes the author will cite examples from his experience and provide some interesting stories of the impact of shifts in approach. One example cited will describe how one tire company improved interior vehicle passenger comfort by making their tires noisier. Another example will describe how changes in product design can create unexpected noise issues and the difficulties encountered in accommodating such nontraditional issues. This will be demonstrated by the story of how bubble wrap saved one OEM engineer's job. To illustrate the need to understand that noise may come about in unusual ways, an example of brake noise which occurred when the brake was not applied will be discussed. Finally, some conclusions will be drawn as to the meaning of the changes that have occurred, and what they may indicate for the future.

Evan B. Davis, Ph.D. Evan B. Davis, Ph.D.
Boeing Technical Fellow

A fascination with the world structural acoustics of light-weigh 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.

Wednesday Luncheon Keynote
Ballroom A
12:00 -1:30 p.m

Beth A. Cooper, PE INCE.Bd.Cert. Fellow INCE/USA Beth A. Cooper, PE INCE.Bd.Cert. Fellow INCE/USA
Acoustical Engineer
John Glenn Research Center, NASA

Beth Cooper is an acoustical engineer and Director of the NASA Auditory Demonstration Laboratory at Glenn Research Center. As an internal hearing conservation consultant to the Office of the Chief Health and Medical Officer, Ms. Cooper provides specialized support for the agency's occupational health and engineering communities to help them meet NASA's hearing conservation program requirements. She also manages the development, promotion, and public distribution of unique multimedia training resources for hearing conservationists and noise control professionals.

From 1999 to 2007, Ms. Cooper managed the conceptual design, construction, accreditation, and ongoing operations of the Glenn Acoustical Testing Laboratory and provided noise control design, testing, and training support to help NASA's science experiment payloads meet International Space Station hearing conservation requirements. Previously, she managed the development and implementation of Glenn Research Center's hearing conservation and community noise programs. Ms. Cooper has managed the design and construction of numerous NASA noise control projects, including three significant NASA acoustical facilities.

Ms. Cooper has served as the Director of Communication of the National Hearing Conservation Association and is a member of the ANSI S12 Accredited Standards Committee on Noise and Working Group #11 on Hearing Protector Attenuation. She is a Fellow of the Institute of Noise Control Engineering (INCE), has served on the INCE Board of Directors, as INCE Vice President for Board Certification, and as General Chair of NoiseCon 2003. She has represented INCE on the Council for Accreditation in Occupational Hearing Conservation (CAOHC), served as Council Chair, and is CAOHC-certified as a Course Director.

Ms. Cooper holds a B.S. in mechanical engineering from the University of Hartford and a M.S. in acoustics from the Pennsylvania State University and has 30 years of professional experience in the field of acoustics, noise control, and hearing conservation.

Multimedia demonstrations of acoustical concepts for more effective presentations

Noise control professionals who wish to educate decision-makers about acoustical and noise control concepts can most effectively advocate for the desired outcome by employing multimedia demonstrations that allow the listener to experience the intended message, whether it be hearing loss prevention strategies, architectural design specifications, or low-noise product recommendations. Presentations that include animated, interactive, and audio demonstrations are more effective because they capture the attention of the audience and promote interaction between the presenter and the audience, whether it be in an employee training environment or as part of a marketing presentation. This program will feature examples of multimedia demonstrations of various acoustical concepts, including noise-induced-hearing loss, acoustical phenomena, noise control properties of materials and speech interference. The process for creating customized auditory demonstrations will be illustrated to show the relationship between concept, filter specification, software implementation, and final product. These popular demonstrations, developed by NASA's Auditory Demonstration Laboratory, are publicly available as free web-based multimedia files and are widely used by educators and acoustical professionals worldwide.
