Seminar - Bayesian Inference in Acoustical Applications by Dr. Ning Xiang

Date:   11 January 2013 (Friday)

Time:   11:00 am – 12:00 pm

Venue:  EF305, The Hong Kong Polytechnic University


Bayesian probability theory has been interpreted as logic of science. It has increasingly found applications in acoustics science and engineering. Bayesian analysis encompasses tow levels of inference within one unified framework; model selection and parameter estimation. After a brief introduction of Bayesian probability theory, this talk will present some recent applications in architectural acoustics, and physical acoustics, such as advanced room-acoustic energy decay analysis, modal analysis, and the model-based porous material inversion.


Dr. Ning Xiang received a Ph.D. in Electrical Engineering at the Ruhr-Universitat Bochum (RUB), Germany, current chair of the Graduate Program in Architectural Acoustics in the School of Architecture at Rensselaer Polytechnic Institute. He has published over 220 papers in peer-reviewed journals and proceedings in research fields including: ultrasonic measurement technology, acoustic detection techniques, automatic target recognition, architectural acoustics, and model-based data analysis. Dr. Xiang is a Fellow of the Acoustical Society of America, the Institute of Acoustics (United Kingdom), and the German Acoustical Society since 1991. Dr. Xiang has been active in the Acoustical Society of America, he is the current Chair of the Technical Committee on Signal Processing in Acoustics. He is also the Associate Editor of the Journal of the Acoustical Society of America (JASA) and Associate Editor of the JASA Express Letters (JASA-EL) for the section Architectural Acoustics.
