Acoustics and Audio Technology, Third Edition

“At last, an easy-to-read volume that has a real bent towards sound reproduction pre¬sented at both the technical and practical levels. Plus, each chapter has problem sets… Overall, a highly recommended book, particularly given its attractive price.”

Mendel Kleiner obtained his Ph.D. in architectural acoustics in 1978 and is currently Professor of Acoustics at Chalmers University of Technology, Gothenburg, Sweden, and in charge of the Chalmers Room Acoustics Group. Dr. Kleiner is responsible for teaching room acoustics, audio, electroacoustics, and ultrasonics in the Chalmers Master Program on Sound and Vibration. He has more than 50 publications, presented keynote lectures and more than 110 papers, has led courses at international conferences on acoustics and noise control, and organized an international conference on acoustics. His main research areas are computer simulation of room acoustics, electroacoustic reverberation enhancement systems, room acoustics of auditoria, sound and vibration measurement technology, product sound quality, and psychoacoustics. Dr. Kleiner is a Fellow of the Acoustical Society of America, the Chair for the Audio Engineering Society’s Technical Committee on Acoustics and Sound Reinforcement and on its Standards committee on Acoustics.
