Ning Xiang

Ning Xiang is a Full Professor and Director of the Architectural Acoustics Program at Rensselaer Polytechnic Institute's School of Architecture. His research advances measurement techniques and computational models for room acoustics, signal processing, and acoustic material characterization.

Education:

• PhD, Ruhr-University Bochum
• BS, Tianjin University

His research integrates Bayesian inference, wave propagation theory, and experimental methods to solve problems in architectural acoustics. Recent work focuses on uncertainty quantification in acoustic measurements, diffusion-equation modeling for reverberation prediction, and spherical array processing for sound source localization.

Publication analysis reveals three primary themes: (1) Bayesian methods for acoustic parameter estimation; (2) novel measurement systems like high-resolution goniometers; and (3) physics-based modeling of complex acoustic phenomena. His articles combine fundamental theory with practical applications across concert hall design, noise control, and acoustic materials development.

Scientific Awards:

• Wallace Clement Sabine Medal (Acoustical Society of America)
• Albert Nelson Marquis Lifetime Achievement Award

As Architectural Acoustics Program Director, he mentors graduate students and leads research on acoustic sensing systems. He serves as Associate Editor for the Journal of the Acoustical Society of America and has chaired multiple technical committees for international acoustics societies.

His laboratory develops advanced instrumentation including laser Doppler vibrometry systems for material characterization and portable goniometers for diffuser evaluation. Current projects include NSF-funded research on Bayesian uncertainty quantification in acoustic measurements.
