Abstract:
Conventional methods for generating high-quality audio are not easily integrated with the thin, lightweight displays used in televisions, smartphones and tablets. As a result, audio quality is often sacrificed to meet the size and form-factor constraints of modern displays. Flat-panel loudspeakers, which radiate sound via the bending motion of a panel, offer a promising means of improving audio quality and satisfying form-factor requirements by employing the display screen itself as a loudspeaker. Though the concept has existed for nearly a century, a number of acoustical challenges have prevented widespread integration into consumer products. New approaches that combine signal-processing with structural control techniques have given flat-panel speakers acoustic properties that are comparable with conventional speakers. These approaches also allow for a number of intriguing applications in spatial audio such as wave field synthesis and audio/visual source pairing, as well as smart speaker technology.

Bio:
Michael Heilemann received his M.S. and Ph.D. in Electrical Engineering from the University of Rochester in 2015 and 2018 respectively. In 2017, he was named the Harman Scholar by the Audio Engineering Society Educational Foundation. After completing his doctoral studies, he joined the faculty at the UR in the Department of Electrical and Computer Engineering. His research interests are in the areas of electro-acoustics and spatial audio. Professor Heilemann advises the capstone projects for students majoring in Audio and Music Engineering, and teaches courses on signal processing and acoustics.
