Ning Xiang, Ph.D.
Chair, Graduate Program in Architectural Acoustics
Professor, School of Architecture and School of Engineering (Dept. of Electrical, Computer, and Systems Engineering)

Dr. Xiang advises graduate-student research and teaches in the courses Sonics Research Lab, Research Methods in Acoustics, and the Graduate Research seminars.

Education:
Ph.D. (EE), Ruhr-University Bochum, Germany, 1990
M.S. (EE), Ruhr-University Bochum, Germany, 1986

Background:
Dr. Ning Xiang earned his Ph. D. in 1990 from the Department of Electrical Engineering at the Ruhr-Universitat Bochum (RUB) in Bochum, Germany (with advisor Prof. Dr. Jens Blauert). Dr. Xiang was then employed as a project manager and R&D engineer for Head Acoustics Inc., Germany, from 1991 to 1996 and subsequently joined the Fraunhofer-Institute for Building Physics, Stuttgart, Germany, as a Research Scientist in 1997. Starting in 1998, he was with the National Center for Physical Acoustics (NCPA) at the University of Mississippi. He was a Research Scientist at the NCPA and a Research Associate Professor in the Department of Electrical Engineering at the University of Mississippi. Dr. Xiang has pursued research in architectural acoustics, auralization, and binaural signal processing with the Institute of Communication Acoustics, Ruhr-University Bochum, Germany. Dr. Xiang has been frequently invited by the International Congress on Acoustics (ICA), the Acoustical Society of America (ASA), the British Institute of Acoustics (IoA), the Audio Engineering Society, the Acoustical Society of East Germany, and the Acoustical Society of Poland. He has published three books and over 300 publications in proceedings and peer-reviewed journals (including J. of the Acoustical Society of America, IEEE, Applied Acoustics and Acta Acustica) in the following research fields: architectural acoustics, binaural auralization and binaural scale-model measurements, auditory virtual reality and binaural signal processing, ultrasonic measurement technology, Bayesian inference, model-based data analysis, automatic target recognition, acoustic technology for landmine detection.
Dr. Xiang is a Fellow of the Acoustical Society of America, a Fellow of the Institute of Acoustics (United Kingdom), a Member of IEEE Signal Processing Society and IEEE Geoscience and Remote Sensing Society, a Member of the Audio Engineering Society, and a Member of German Acoustical Society. Currently Dr. Xiang serves as an Associate Editor of the Architectural Acoustics Section of the Journal of the Acoustical Society of America, and as an Associate Editor of the Express-Letters of the Journal of the Acoustical Society of America.

Current Acoustics Research Interests:
Architectural acoustics, binaural auralization and binaural scale-model measurements, auditory virtual reality and binaural signal processing, advanced acoustical measurement techniques, medical ultrasonic measurements, model-based data analysis, automatic target recognition, Bayesian inference, acoustic technology for landmine detection.

Jonas Braasch
Associate Professor, School of Architecture

Dr. Braasch advises graduate-student research and teaches in the courses Applied Psychoacoustics, Sonics Research Lab, Advanced Projects in Acoustics, and the Graduate Research seminars.

Education:
Ph.D. (Musicology), Ruhr-University Bochum, 2004
D. Eng. (EE), Ruhr-University Bochum, 2001
Diplom-Physik (M.S., Physics), Dortmund University, 1998

Background:
Before coming to RPI, Dr. Braasch studied physics at the University of Dortmund from 1992 until 1998. Afterwards, he received a three-year doctoral scholarship within the neuroscien tific graduate school "KOGNET" (cognition, neuronal networks) at the Ruhr-University Bochum. Dr. Braasch continued to work at the Institute of Communication Acoustics at the Ruhr-University Bochum in the position of a Research Associate from March 2001 until Dec. 2003, and managed the group "Auditory Signal Processing and Binaural Technology". With the beginning of the year 2004, Dr. Braasch started to work as a Research Associate in the Sound Recording Area of the Faculty of Music at McGill University. In Nov. 2004, he was moved to the rank of Assistant Professor (Special Category).

Dr. Braasch started his research career in the field of binaural hearing as a doctoral student of Dr. Jens Blauert, and has continued to investigate various aspects of spatial hearing in complex scenarios. Currently, he is applying binaural models for the acoustical quality assessment of concert spaces. Jonas Braasch second field of research is related to musical acoustics (History and Technology of Musical Instruments). He has conducted a number of investigations on the free-reed stops of concert-hall and church organs. In 2004, he completed his Ph.D. thesis in this field at the Institute of Musicology of the Ruhr-University Bochum (advisor Dr. Christian Ahrens). Dr. Braasch is very much interested on how musical instruments interact with the concert space during a performance. He has also been active in the design of auditory virtual environments. Currently he continues to develop an environment to simulate classic Tonmeister microphone techniques based on "Virtual Microphone Control" (ViMiC). Currently, he is working with Dr. Blauert on a new edition of Dr. Blauert's classic textbook "Spatial Hearing" (MIT press).

Dr. Braasch is the author/coauthor of two monographs and 40 articles that appeared in peer-reviewed journals and conference proceedings. He is a member of the Committee in Musical Acoustics of the American Acoustical Society. He is also a member of the German Acoustical Society (DEGA), the Audio Engineering Society and the German Pipe-Organ Society (GdO).

Current Acoustics Research Interests:
Auditory signal processing, binaural technology, musical acoustics, multi-channel audio applications, audio engineering, auditory virtual reality, musique concrete
