Abstract: Three-dimensional sound can be found in enclosures such as offices, factory spaces, auditoria and concert halls. The behavior and complexity of the 3D sound field influences factors such as speech intelligibility in rooms, music perception in concert halls, and noise annoyance in factories. Recent developments in spherical microphone arrays have paved the way for improved methods to measure, analyze and process 3D sound fields. Aspects of spherical array signal processing will be presented, including application examples highlighting the advantages of signal processing in the spherical harmonics domain.

Biography: Boaz Rafaely received the B.Sc. degree (cum laude) in electrical engineering from Ben-Gurion University, Beer-Sheva, Israel, in 1986; the M.Sc. degree in biomedical engineering from Tel-Aviv University, Israel, in 1994; and the Ph.D. degree from the Institute of Sound and Vibration Research (ISVR), Southampton University, U.K., in 1997. At the ISVR , he was appointed Lecturer in 1997 and Senior Lecturer in 2001, working on active control of sound and organizing the modular M.Sc. degree in applied digital signal processing. In 2002, he spent six months as a Visiting Scientist at the Sensory Communication Group, Research Laboratory of Electronics, Massachusetts Institute of Technology (MIT), Cambridge, investigating speech enhancement for hearing aids. He then joined the Department of Electrical and Computer Engineering at Ben-Gurion University as a Senior Lecturer in 2003, where he is currently teaching acoustics and signal processing and heading the acoustics laboratory, investigating sound fields by microphone and loudspeaker arrays.
