The Audio Spotlight: Beams of Sound from Ultrasound

F. Joseph Pompei, Holosonics

Friday, March 2, 2012, 3:30pm

Spanos Auditorium

This seminar is part of the Jones Seminars on Science, Technology, and Society series.

Audio Spotlight technology allows extremely narrow beams of sound to be generated via the nonlinear interaction of ultrasound in air. Invented at MIT by Dr. Joseph Pompei, the technology has been commercialized and is now widely adapted for display applications, private listening in shared spaces, artistic use, and special effects. The physics and mathematics behind the technology will be presented, along with a live demonstration, and various real-world applications will be discussed.

About the Speaker

Dr. Joseph Pompei began his career in acoustics at 16 as the youngest engineer at Bose Corporation, continuing at Bose while earning a degree in Electrical Engineering with an Electronic Arts minor from Rensselaer Polytechnic Institute. Recognizing the importance and underutilization of spatialized sound, he decided to pursue research in psychoacoustics at Northwestern University, earning a Master's degree. Acutely aware of the limitations of traditional loudspeakers, he had the idea of using ultrasound as an acoustic projector, calling it the "Audio Spotlight," and developed the fundamental technology at the MIT Media Lab while earning his Ph.D. Without external investors, he founded Holosonics.
