Acoustics for Engineers

Ning Xiang, PhD, is professor of Acoustics and Signal Processing at the Rensselaer Polytechnic Institute (RPI) in Troy, New York. He is the director of RPI’s Program in Architectural Acoustics. Jens Blauert, Dr.-Ing., Dr.-Tech. h.c., is emeritus professor of Acoustics and Electrical Engineering at the Ruhr-University Bochum (RUB) in Bochum, Germany. He is the founder and former director of RUB’s Institute of Communication Acoustics.

“The book is systematic but concise, covering the acoustic basics required for engineering applications, as well as electroacoustic transducers, room acoustics, noise control, and more aspects of the fundamentals. … it is also beneficial to engineers and technicians engaged in the development of related technologies, so it is hereby recommended.” (ACTA ACUSTICA, Vol. 48 (4), 2023)“As its title suggests, the book takes a structured, engineering approach. … It also serves as a reference book to delve deeper into individual topics or to revisit buried knowledge. … Acoustics for Engineers is convincing in its brevity and structure and is consequently recommended to all readers who, in addition to a well-illustrated presentation of the fundamentals of acoustics and electro-acoustics, are interested in their derivations, correlations, and analogies, as well as in the calculation of typical problems.” (Martin Schneider, vdt Magazin, Issue (2), 2022)
