ABOUT
Dr. Mingsian R. Bai received his Ph.D. in engineering mechanics and aerospace engineering from Iowa State University in 1989. As a Tsing Hua distinguished professor, he has published 115 archive journal articles, 60 conference papers and 6 books in the areas of acoustics, audio signal processing, and electroacoustic transducers. He has more than 40 granted or pending patents. Before he joined the PME of HTHU in August 2010, he has been with the ME of NCTU during 1989-2010. He was also a visiting scholar to Center of Vibration and Acoustics, Penn State University, University of Adelaide, Australia, and Institute of Sound and Vibration Research (ISVR), UK in 1997, 2000, 2002, respectively.
His current interests encompass acoustics, audio signal processing, telecom acoustics, microphone arrays, electroacoustic transducers, vibroacoustic diagnostics, active noise and vibration control, and so forth. He is in charge of the Telecom, Electroacoustics, Audio (TEA) laboratory of NTHU. He currently serves as an active consultant and project leader in these areas in industry. He has received numerous academic awards including the Outstanding Research Award from National Science Council in 2006 and 2010. Professor Bai is a member of the Institute of Electrical and Electronics Engineers (IEEE), the Audio Engineering Society (AES), the Acoustical Society of America (ASA), the Acoustical Society of Taiwan, and the Vibration and Noise Control Engineering Society in Taiwan. He currently serves as an associate editor in Journal of the Acoustical Society of America (JASA).
