Lance Willis, PhD, Principal Acoustical Engineer

Dr. Willis holds a Bachelor of Mechanical Engineering (1993), Master of Science in Mechanical Engineering (1995), and a Ph.D. with a Multi-disciplinary Certificate in Acoustics (1999) from the Georgia Institute of Technology. Graduate work, done under Dr. Yves Berthelot, involved using laser vibrometry to measure the complex dynamic material properties of viscoelastic materials under varying temperature and pressure. During this time he also worked closely with Dr. Eugene Patronis in the School of Physics on various loudspeaker and acoustical projects.

In 2000, Dr. Willis began work in Motorola's Advanced Product Technology Center. Projects at Motorola included the acoustical design of portable radio products with respect to speaker and microphone performance, sound quality, and operation in wet and noisy environments, studies of rub and buzz detection methods, managing the development of a high efficiency family of speakers, and modal analysis of microspeaker cones to reduce audible distortion.

Dr. Willis is a member of the Acoustical Society of America (ASA), the Audio Engineering Society (AES), and American Loudspeaker Manufacturers Association (ALMA). He has been awarded two patents for adaptive equalization in behind the ear telephony devices.
